Steamworks, anapplication programming interface(API) released in 2008, is used by developers to integrate Steam's functions, includingdigital rights management(DRM), into their products. Severalgame publishersbegan distributing their products on Steam that year. Initially developed forWindows,Steam was ported tomacOSandLinuxin 2010 and 2013 respectively, while a mobile version of Steam for interacting with the service's online features was released oniOSandAndroidin 2012.

The service is the largest digital distribution platform forPC games,with an estimated 75% of the market share in 2013 according toIHS Screen Digest.By 2017, game purchases through Steam totaled aboutUS$4.3 billion, or at least 18% of global PC game sales according toSteam Spy.By 2021, the service had over 34,000 games with over 132 million monthly active users.Steam's success has led to the development of theSteam Machinegaming PCs in 2015, including theSteamOSLinux distribution andSteam Controller;Steam Linkdevices for local game streaming; and in 2022, the handheldSteam Decktailored for running Steam games.

In the early 2000s, Valve was looking for a better way to update its published games,as providing downloadablepatchesfor multiplayer games resulted in most users disconnecting for several days until they had installed the patch. They decided to create a platform that would update games automatically, and implement strongeranti-piracyandanti-cheatmeasures. They approached several companies, includingMicrosoft,Yahoo!,andRealNetworks,to build a client with these features, but were rejected.

Valve began its own platform development in 2002, using the working names "Grid" and "Gazelle".The Steam platform was announced at theGame Developers Conferenceevent on March 22, 2002, and released forbeta testingthat day.Prior to the implementation of Steam, Valve had a publishing contract withSierra Studios;the 2001 version of the contract gave Valve rights to digital distribution of its games.Valve took Sierra and its owners,Vivendi Games,to court in 2002 over a claimed breach of contract. Sierra counter-sued, asserting that Valve had undermined the contract by offering a digital storefront for their games, to compete directly with Sierra.

Steam was released out of beta on September 12, 2003.In November 2004,Half-Life 2was the first high-profile game to be offered digitally on Steam, requiring installation of the Steam client for retail copies. During this time users faced problems attempting to play; part of legal issues that Valve had with Vivendi, who claimed that physical copies they published could not be activated as to them the game had not been released.The Steam requirement was met with concerns about software ownership and requirements, as well as problems with overloaded servers - demonstrated previously by theCounter-Strikerollout.

In 2005, third-party developers were contracted to release games on Steam, such asRag Doll Kung FuandDarwinia.In May 2007, ATI included Steam in theATI CatalystGPU driver as well as offering a free Steam copy ofHalf-Life 2: Lost CoastandHalf-Life 2: Deathmatchto ATI Radeon owners.In January 2008,Nvidiapromoted Steam in theGeForceGPU driver, as well as offering a free Steam copy ofPortal: The First Sliceto Nvidia hardware owners.

In 2011, someElectronic Artsgames, such asCrysis 2,Dragon Age II,andAlice: Madness Returns,were removed from sale because of terms of service that prevented them having their own in-game storefront for downloadable content. These were later launched on theOriginservice.

In 2019, Ubisoft announced that it would stop selling future games on Steam, starting withTom Clancy's The Division 2because Valve would not modify its revenue sharing model.In May 2019, Microsoft distributed its games on Steam in addition to theMicrosoft Store.

In 2020, Electronic Arts started to publish selected games on Steam, and offered its rebranded subscription serviceEA Playon the platform.In 2022, Ubisoft announced that it would return to selling its recent games on Steam, starting withAssassin's Creed Valhalla,stating that it was "constantly evaluating how to bring our games to different audiences wherever they are".

By 2014, total annual game sales on Steam were estimated at $1.5 billion.By 2018, the service had over 90 million monthly active users.In 2018, its network delivered 15 billion gigabytes of data, compared to less than 4 billion in 2014.

Features and functionality

Software delivery and maintenance

Steam's primary service is to allow its users topurchase games and other software,adding them to a virtual library from which they may be downloaded and installed an unlimited number of times. Initially, Valve was required to be the publisher for these games since they had sole access to Steam's database and engine, but with the introduction of the Steamworkssoftware development kit(SDK) in May 2008, anyone could integrate Steam into their game without Valve's direct involvement.

Valve intended to "make DRM obsolete" as games released on Steam had traditionalanti-piracymeasures, including the assignment and distribution ofproduct keysand support fordigital rights managementsoftware tools such asSecuROMor non-maliciousrootkits.With an update to the Steamworks SDK in March 2009, Valve added "Custom Executable Generation" (CEG), which creates a unique, encrypted copy of the game's executable files for the given user, which allows them to install it multiple times and on multiple devices, and make backup copies of their software.Once the software is downloaded and installed, the user must then authenticate through Steam to de-encrypt the executable files to play the game. Normally this is done while connected to the Internet following the user's credential validation, but once they have logged into Steam once, a user can instruct Steam to launch in a special offline mode to be able to play their games without a network connection.Developers are not limited to Steam's CEG and may include other forms of DRM (or none at all) and other authentication services than Steam; for example, some games from publisherUbisoftrequire the use of theirUplaygaming service.

In September 2008, Valve added support for Steam Cloud, a service that can automatically store saved game and related custom files on Valve's servers; users can access this data from any machine running the Steam client.Users can disable this feature on a per-game and per-account basis.Cloud saving was expanded in January 2022 for Dynamic Cloud Sync, allowing games developed with this feature to store saved states to Steam Cloud while a game is running rather than waiting until the user quit; this was added ahead of the portable Steam Deck unit so that users can save from the Deck and then put the unit into a suspended state.In May 2012, the service added the ability for users to manage their game libraries from remote clients, including computers and mobile devices.Product keyssold through third-party retailers can also be redeemed on Steam.For games that incorporate Steamworks, users can buy redemption codes from other vendors and redeem these in the Steam client to add the title to their libraries. Steam also offers a framework for selling and distributingdownloadable content(DLC) for games.

In September 2013, Steam introduced the ability to share most games with family members and close friends by authorizing machines to access one's library. Authorized players can install the game locally and play it separately from the owning account. Users can access their saved games and achievements provided the main owner is not playing. When the main player initiates a game while a shared account is using it, the shared account user is allowed a few minutes to either save their progress and close the game or purchase the game for their own account.Within Family View, introduced in January 2014, parents can adjust settings for their children's tied accounts, limiting the functionality and accessibility to the Steam client and purchased games.A more robust implementation of Family Sharing, titled "Steam Families", was released in September 2024, allowing up to five members of a household to share games from a single account, including the ability to play different games on those accounts along with different game saves and profiles, and enhanced parental control tools for those accounts.

By itsacceptable use policy,Valve retains the right to block customers' access to their games and Steam services when Valve's Anti-Cheat (VAC) software determines that the user is cheating in multiplayer games, selling accounts to others, or trading games to exploit regional price differences.Blocking such users initially removed access to their other games, leading to some users with high-value accounts losing access because of minor infractions.Valve later changed its policy to be similar to that of Electronic Arts'Originplatform, in which blocked users can still access their games but are heavily restricted, limited to playing in offline mode and unable to participate in Steam Community features.Customers also lose access to their games and Steam account if they refuse to accept changes to Steam'send user license agreements;this last occurred in August 2012.In April 2015, Valve began allowing developers to set bans on players for their games, but enacted and enforced at the Steam level, which allowed them to police their own gaming communities in a customizable manner.

Storefront features

The Steam client includes a digital storefront called the Steam Store through which users can purchase games. Once the game is bought, a software license is permanently attached to the user's Steam account, allowing them to download the software on any compatible device. Game licenses can be given to other accounts under certain conditions. Content is delivered from an international network of servers using a proprietary file transferprotocol.Products sold on Steam are available for sale in different currencies, which changes depending on the user's location.In December 2010, the storefront began supportingWebMoneyfor payments,and from April 2016 until December 2017 supportedBitcoinpayments before dropping support due to high value fluctuations and costly service fees.The Steam storefront validates the user's region; the purchase of games may be restricted to specific regions because of release dates, game classification, or agreements with publishers. Since 2010, theSteam Translation Serverproject allows Steam users to assist with the translation of the Steam client, storefront, and a selected library of Steam games for twenty-eight languages.In October 2018, official support for Vietnamese and Latin American Spanish was added, in addition to Steam's then 26 languages.Steam also allows users to purchasedownloadable contentfor games, and for some specific games such asTeam Fortress 2,the ability to purchase in-game inventory items. In February 2015, Steam began to open similar options for in-game item purchases for third-party games.In November 2007, achievements were added, similar toXbox 360 Achievements.

In conjunction with developers and publishers, Valve frequently provides discounted sales on games on a daily and weekly basis, sometimes oriented around a publisher, genre, or holiday theme, and sometimes allows games to be tried for free during the days of these sales. The site normally offers a large selection of games at a discount during its annual Summer and Holiday sales, includinggamificationof these sales.

Users of Steam's storefront can also purchase games and other software as gifts for another Steam user. Before May 2017, users could purchase these gifts to be held in their profile's inventory until they opted to gift them. However, this feature enabled agray marketaround some games, where a user in a country where the price of a game was substantially lower than elsewhere could stockpile giftable copies to sell to others in regions with much higher prices.In August 2016, Valve changed its gifting policy to require that games with VAC and Game Ban-enabled games be gifted immediately to another Steam user, which also served to combat players that worked around VAC and Game Bans;in May 2017, Valve expanded this policy to all games.The changes also placed limitations on gifts between users of different countries if there is a large difference in pricing.Due to runaway inflation in Argentina and Turkey, Valve eliminated the use of local currency pricing for users in those storefronts in November 2023, instead moving them to a special regional pricing model based on U.S. dollars as a means to provide fair payments to publisher and developers, though these local users saw effective price hikes as high as 2900%.

The Steam store also enables users to redeem storeproduct keysto add software from their library. The keys are sold by third-party providers such asHumble Bundle,distributed as part of a physical release, or given to a user as part of promotions, often used to deliverKickstarterand other crowdfunding rewards. Agrey marketexists around Steam keys, where less reputable buyers purchase a large number of Steam keys for a game when it is offered for a low cost, and then resell these keys to users or other third-party sites at a higher price.This caused some of these third-party sites, such asG2A,to be embroiled in this grey market.It is possible for publishers to have Valve track down where specific keys have been used and cancel them, removing the product from the user's libraries.Other legitimate storefronts, like Humble Bundle, have set a minimum price that must be spent to obtain Steam keys as to discourage mass purchases.In June 2021, Valve began limiting how frequently Steam users could change their default region to prevent them from purchasing games from outside their home region for cheaper.

In 2013, Steam began to accept player reviews of games. Other users can subsequently rate these reviews as helpful, humorous, or otherwise unhelpful, which are then used to highlight the most useful reviews on the game's Steam store page. Steam also aggregates these reviews and enables users to sort products based on this feedback while browsing the store.In May 2016, Steam further broke out these aggregations between all reviews overall and those made more recently in the last 30 days, a change Valve acknowledges to how game updates, particularly those in Early Access, can alter the impression of a game to users.To prevent observed abuse of the review system by developers or other third-party agents, Valve modified the review system in September 2016 to discount review scores for a game from users that activated the product through a product key rather than directly purchased by the Steam Store, though their reviews remain visible.Alongside this, Valve announced that it would end business relations with any developer or publisher that they found to be abusing the review system.Separately, Valve has taken actions to minimize the effects ofreview bombson Steam. In particular, Valve announced in March 2019 that they mark reviews they believe are "off-topic" as a result of a review bomb, and eliminate their contribution to summary review scores; the first such games they took action on with this were theBorderlandsgames after it was announcedBorderlands 3would be a timed-exclusive to theEpic Games Store.

Valve added support forfree-to-playgames on Steam as well as support for in-gamemicrotransactionsthrough the use of Steamworks in June 2011,while support was added in September 2011 for trading in-game items and "unopened" gifts between users.Steam Coupons, which was introduced in December 2011, provides single-use coupons that provide a discount to the cost of items. Steam Coupons can be provided to users by developers and publishers; users can trade these coupons between friends in a similar fashion to gifts and in-game items.In May 2015,GameStopbegan selling Steam Wallet cards.Steam Market, a feature introduced in beta in December 2012 that would allow users to sell virtual items to others via Steam Wallet funds, further extended the idea. Valve levies a transaction fee of 15% on such sales and game publishers that use Steam Market pay a transaction fee. For example,Team Fortress 2—the first game supported at the beta phase—incurred both fees. Full support for other games was expected to be available in early 2013.In April 2013, Valve added subscription-based game support to Steam; the first game to use this service wasDarkfall Unholy Wars.

In October 2012, Steam introduced non-gaming applications, which are sold through the service in the same manner as games.Creativity and productivity applications can access the core functions of the Steamworks API, allowing them to use Steam's simplified installation and updating process, and incorporate features including cloud saving and Steam Workshop.Steam also allowsgame soundtracksto be purchased to be played via Steam Music or integrated with the user's othermedia players.Valve adjusted its approach to soundtracks in 2020, no longer requiring them to be offered as DLC, meaning that users can buy soundtracks to games they do not own, and publishers can offer soundtracks to games not on Steam.

Valve has also added the ability for publishers to rent and sell digital movies via the service, with initially most being video game documentaries.FollowingWarner Bros. Entertainmentoffering theMad Maxfilms alongside the September 2015 release of thegame based on the series,Lionsgateentered into agreement with Valve to rent over one hundred feature films from its catalog through Steam starting in April 2016, with more films following later.In March 2017,Crunchyrollstarted offering variousanimefor purchase or rent through Steam.However, by February 2019, Valve shuttered video from its storefront save for videos directly related to gaming content.While available, users could also purchaseSteam Machinerelated hardware.

Valve took a flat 30%shareof all revenue generated from direct Steam sales and microtransactionsuntil October 2018 when they changed their policy to reduce the cut to 25% once revenue for a game surpassesUS$10 million,and further to 20% atUS$50 million.The policy change was seen by journalists as trying to entice larger developers to stay with Steam,while the decision was also met with backlash from indie and other small game developers, as their revenue split remained unchanged.

While Steam allows developers to offer demo versions of their games at any time, Valve worked withGeoff Keighleyin 2019 in conjunction withThe Game Awardsto hold a week-long Steam Game Festival to feature a large selection of game demos of current and upcoming games, alongside sales for games already released.This event has since been repeated two or three times a year, typically in conjunction with game expositions or award events, and since has been renamed as the Steam Next Fest.Valve expanded support for demo versions of games in July 2024, allowing demos to have their own store page with user reviews and made it easier for user to manage demos within their game library.

A Steam Points system and storefront was added in June 2020, which mirrored similar temporary points systems that had been used in prior sales on the storefront. Users earn points through purchases on Steam or by receiving community recognition for helpful reviews or discussion comments. These points can be redeemed in the separate storefront for cosmetics that apply to the user's profile and chat interface.

Privacy, security and abuse

The popularity of Steam has led to the services being attacked byhackers.An attempt occurred in November 2011, when Valve temporarily closed the community forums, citing potential hacking threats to the service. Days later, Valve reported that the hack had compromised one of its customer databases, potentially allowing the perpetrators to access customer information, including encrypted passwords and credit card details. At that time, Valve was not aware whether the intruders actually accessed this information or discovered the encryption method, but nevertheless warned users to be alert for fraudulent activity.

Valve launched Steam Guard in March 2011 with the goal of protecting Steam users against account hijacking viaphishingschemes, one of the largest security problems Valve had at the time.Steam Guard was advertised to take advantage of the identity protection provided by Intel's second-generationCoreprocessors and compatible motherboard hardware, which allows users to lock their account to a specific computer. Once locked, activity by that account on other computers must first be approved by the user on the locked computer. Support APIs for Steam Guard are available to third-party developers through Steamworks.Steam Guard also offerstwo-factor,risk-based authenticationthat uses a one-time verification code sent to a verified email address associated with the Steam account; this was later expanded to include two-factor authentication through the Steam mobile application, known as Steam Guard Mobile Authenticator.

In 2015, Valve stated that the potential monetary value of virtual goods attached to user accounts had drawn hackers to try to access accounts for financial benefit.Valve reported that in December 2015, around 77,000 accounts per month were hijacked, enabling the hijackers to empty the user's inventory of items through the trading features. To improve security, the company announced that new restrictions would be added in March 2016, under which 15-day holds are placed on traded items unless they activate, and authenticate with Steam Guard Mobile Authenticator.After aCounter-Strike: Global Offensivegambling controversy, Valve stated it was cracking down on third-party websites using Steam inventory trading forskin gamblingin July 2016.

ReVuln, a commercial vulnerability research firm, published a paper in October 2012 that said the Steam browser protocol was posing a security risk by enabling malicious exploits through a simple user click on a maliciously craftedsteam://URL in a browser.This was the second serious vulnerability of gaming-related software following a problem with Ubisoft'sUplay.German IT platformHeise onlinerecommended strict separation of gaming and sensitive data, for example using a PC dedicated to gaming, gaming from a second Windows installation, or using a computer account with limited rights dedicated to gaming.

In July 2015, a bug in the software allowed anyone to reset the password to any account by using the "forgot password" function of the client. High-profile professional gamers andstreamerslost access to their accounts.In December 2015, Steam'scontent delivery networkwas misconfigured in response to aDDoS attack,causing cached store pages containing personal information to be temporarily exposed for 34,000 users.

Valve added new privacy settings to Steam in April 2018, allowing users to hide their activity status, game lists, inventory, and other profile elements. While these changes brought Steam's privacy settings in line with services such asPlayStation Networkand theXbox network,third-party services such asSteam Spywere impacted, due to their reliance on public data to estimate Steam product sales.

Valve established aHackerOnebug bounty program in May 2018, a crowdsourced method to test and improve the security features of the Steam client.In August 2019, a security researcher exposed azero-day vulnerabilityin the Windows client of Steam, which allowed for any user to run arbitrary code with LocalSystem privileges using just a few simple commands. The vulnerability was then reported to Valve via the program, but it was initially rejected for being "out-of-scope". Following a second vulnerability found by the same user, Valve apologized and patched them both, and expanded the program's rules to accept any other similar problems.

TheAnti-Defamation Leaguepublished a report that stated theSteam Communityplatform harbors hateful content in April 2020.In January 2021, a trading card glitch let players generate Steam Wallet funds from free Steam trading cards withbotsusingCapcom Arcade Stadiumand other games, resulting in the game becoming one of the statistically most played titles.

User interface and functionality

Since November 2013, Steam has allowed for users to review their purchased games and organize them into categories set by the user and add to favorite lists for quick access. Players can add non-Steam games to their libraries, allowing the game to be easily accessed from the Steam client and providing support where possible for Steam Overlay features. The Steam interface allows for user-defined shortcuts to be added. In this way, third-party modifications and games not purchased through the Steam Store can use Steam features. Valve sponsors and distributes some modifications free of charge;and modifications that useSteamworkscan also use any Steam features supported by their parent game. For most games launched from Steam, the client provides an in-game overlay from which the user can access Steam Community lists and participate in chat, manage selected Steam settings, and access a built-inweb browserwithout having to exit the game.Since the beginning of February 2011 as a beta version, the overlay also allows players to takescreenshotsof the games in process.As a full version on February 24, 2011, this feature was reimplemented so that users could share screenshots on websites ofFacebook,Twitter,andRedditdirectly from a user's screenshot manager.Store game pages display a score fromMetacriticsince 2007.

Steam's "Big Picture" mode is more optimized for a larger screen with a larger, simpler interface that mimics the Steam Deck interface and is easily navigable with either a controller or mouse.

Steam's "Big Picture" mode was announced in 2011;public betas started in September 2012 and were integrated into the software in December 2012.Big Picture mode is a10-foot user interface,which optimizes the Steam display to work on high-definition televisions, allowing the user to control Steam with a gamepad or with a keyboard and mouse.Gabe Newellstated that Big Picture mode was a step towards a dedicated Steam entertainment hardware unit.With the introduction of the Steam Deck, Valve began pushing the new Big Picture mode based on the Steam Deck UI in beta testing in October 2022, and full release in February 2023.The new UI was also adopted by SteamVR in October 2023.

In 2012, Valve announcedSteam for Schools,a free function-limited version of the Steam client for schools.It was part of Valve's initiative to supportgamification of learning.It was released alongside free versions ofPortal 2and a standalone program called "Puzzle Maker" that allowed teachers and students to create and manipulate levels. It featured additional authentication security that allowed teachers to share and distribute content via a Steam Workshop-type interface but blocks access from students.

In-Home Streaming was introduced in May 2014; it allows users to stream games installed on one computer to another on the same home network with low latency.By June 2019, Valve renamed this feature to Remote Play, allowing users to stream games across devices that may be outside of their home network.Steam's "Remote Play Together", added in November 2019 after a month of beta testing, gives the ability for local multiplayer games to be played by people in disparate locations, though will not necessary resolve latency problems typical of these types of games.Remote Play Together was expanded in February 2021 to give the ability to invite non-Steam players to play through a Steam Link app approach.

The Steam client, as part of asocial network service,allows users to identify friends and join groups using the Steam Community feature.Through the Steam Chat feature, users can use text chat andpeer-to-peerVoIPwith other users, identify which games their friends and other group members are playing, and join and invite friends to Steamworks-based multiplayer games that support this feature. Users can participate in forums hosted by Valve to discuss Steam games. Each user has a unique page that shows his or her groups and friends, game library including earned achievements, game wishlists, and other social features; users can choose to keep this information private.In January 2010, Valve reported that 10 million of the 25 million active Steam accounts had signed up to Steam Community.In conjunction with the 2012 Steam Summer Sale, user profiles were updated with Badges reflecting the user's participation in the Steam community and past events.Steam Trading Cards,a system where players earn virtual trading cards based on games they own, were introduced in May 2013. Using them, players can trade with other Steam users on the Steam Community Marketplace and use them to craft "Badges", which grant rewards such as discount coupons, and user profile page customization options.In 2010, the Steam client became anOpenIDprovider, allowing third-party websites to use a Steam user's identity without requiring the user to expose his or her Steam credentials.In order to prevent abuse, access to most community features is restricted until a one-time payment of at leastUS$5 is made to Valve. This requirement can be fulfilled by making any purchase of five dollars or more on Steam, or by adding at the same amount to their wallet.

Through Steamworks, Steam provides a means of server browsing for multiplayer games that use the Steam Community features, allowing users to create lobbies with friends or members of common groups. Steamworks also providesValve Anti-Cheat(VAC), Valve's anti-cheat system; game servers automatically detect and report users who are usingcheatsin online, multiplayer games.In August 2012, Valve added new features—including dedicated hub pages for games that highlight the best user-created content, top forum posts, and screenshots—to the Community area.In December 2012, a feature where users can upload walkthroughs and guides detailing game strategy was added.Starting in January 2015, the Steam client allowed players tolivestreamto Steam friends or the public while playing games on the platform.For the main event ofThe International 2018Dota 2tournament, Valve launched Steam.tv as a major update to Steam Broadcasting, adding Steam Chat and Steamworks integration for spectating matches played at the event.It has also been used for other events, such as a pre-release tournament for the digital card gameArtifactand forThe Game Awards 2018andSteam Awardsaward shows.Game Recording was added in beta in June 2024 and released in full by November 2024, allowing for recording of gameplay sessions both on demand or as a background recording. Users can then edit and clip footage to share via Steam with other users.

In September 2014, Steam Music was added to the Steam client, allowing users to play through music stored on their computer or to stream from a locally networked computer directly in Steam.An update to the friends and chat system was released in July 2018, allowing for non-peer-to-peer chats integrated with voice chat and other features that were compared toDiscord.A standalone mobile app based on this forAndroidandiOSwas released in May 2019.

A major visual overhaul of the Library was released in October 2019,with the goal of aiding users in organizing their games, help showcase what shared games a user's friends are playing, games that are being live-streamed, and new content that may be available, along with more customization options for sorting games. Along with the redesign, Valve launched Steam Events, allowing game developers to communicate when new in-game events are approaching, which appear to players in the Library and game listings.

In June 2023, a visual and architectural overhaul was released, unifying the backend functions of the Steam and Steam Deck clients and redesigning the desktop client. As part of this, the in-game overlay received a new customizable design where users can pin windows such as chat or game guides on top of the current game window. It also received several new features, including the ability to create pinnable personal notes stored in the cloud.

Developer features

Valve provides developers the ability to create storefront pages to help generate interest in their game ahead of release.This is also necessary to fix a release date that functions into Valve's "build review", a free service performed by Valve about a week before this release date to make sure the game's launch is trouble-free.Updates in 2020 to Discovery queues have given developers more options for customizing their storefront page and how these pages integrate with users' experiences with the Steam client.

Valve offers Steamworks, anapplication programming interface(API) that provides development and publishing tools free of charge to game and software developers.Steamworks provides networking and player authentication tools for both server and peer-to-peer multiplayer games,matchmakingservices, support for Steam community friends and groups, Steam statistics and achievements, integrated voice communications, and Steam Cloud support, allowing games to integrate with the Steam client. The API also provides anti-cheating devices and digital copy management.In 2016, after introducing theSteam Controllerand improvements to the Steam interface to support numerous customization options, the Steamworks API was also updated to provide a generic controller library for developers and these customization features for other third-party controllers, starting with theDualShock 4.Steam's Input API has since been updated to include official support for other console controllers such as theNintendo Switch Pro Controllerin 2018,theXbox Wireless Controllerfor theXbox Series X and Series Sconsoles, and thePlayStation 5'sDualSense,as well as compatible controllers from third-party manufacturers in 2020.In November 2020, Valve said the controller usage had more than doubled over the past 2 years.In March 2019, Steam's game server network was opened to third-party developers.

Developers of software available on Steam can track sales of their games through the Steam store. In February 2014, Valve announced that it would begin to allow developers to set up their own sales for their games independent of any sales that Valve may set.Valve may also work with developers to suggest their participation in sales on themed days.

Steam has conducted and partially published a monthly opt-in hardware and software survey between 2007 and 2010.

Valve added the ability for developers to sell games under anearly accessmodel with a special section of the Steam store, starting in March 2013. This program allows developers to release functional, but not finished, products such as beta versions to the service to allow users to buy the games and help provide testing and feedback towards the final production. Early access also helps to provide funding to the developers to help complete their games.The early access approach allowed more developers to publish games onto the Steam service without the need for Valve's direct curation of games, significantly increasing the number of available games on the service.Valve added Steam Playtest for developers in 2020, allowing them to run closed beta testing for their games prior to a public release.

Developers can request Steam keys of their products to use as they see fit, such as to give away in promotions, to provide to selected users for review, or to give to key resellers for different prioritization. Valve generally honors all such requests, but clarified that they would evaluate some requests to avoid giving keys to games or other offerings that are designed to manipulate the Steam storefront and other features.

Valve enabled the ability for multiple developers to create bundles of games from their offerings in June 2021.

Steam Workshop

The Steam Workshop is a service that allows users to share user-made content andmodificationsfor video games available on Steam. New levels, art assets, gameplay modifications, or other content may be published to or installed from the Workshop depending on the title. The Workshop was originally used for distribution of new in-game items forTeam Fortress 2;it was redesigned to extend support for any game in early 2012, including modifications forThe Elder Scrolls V: Skyrim.A May 2012 patch forPortal 2,enabled by a new map-making tool through the Workshop, introduced the ability to share user-created levels.Independently developed games, includingDungeons of Dredmor,are able to provide Workshop support for user-made content.Dota 2became Valve's third published title available for the Workshop in June 2012; its features include customizable accessories, characterskins,and announcer packs.Workshop content may be monetized; Newell said that the Workshop was inspired bygold farmingfromWorld of Warcraftto find a way to incentive both players and content creators in video games, and which had informed them of their approach toTeam Fortress 2and their later multiplayer games.

By January 2015, Valve themselves had provided some user-developed Workshop content as paid-for features in Valve-developed games, includingTeam Fortress 2andDota 2;with over $57 million being paid to content creators using the Workshop.Valve began allowing developers to use these advanced features in January 2015; both the developer and content generator share the profits of the sale of these items; the feature went live in April 2015, starting with various mods forSkyrim.This feature was pulled a few days afterward followingnegative user feedback and reports of pricing and copyright misuse.Six months later, Valve stated they were still interested in offering this type of functionality in the future.In November 2015, the Steam client was updated with the ability for game developers to offer in-game items for direct sale via the store interface, withRustbeing the first game to use the feature.

SteamVR

SteamVR is avirtual realityhardware and software platform developed by Valve, with a focus on allowing "room-scale" experiences usingpositional trackingbase stations, as opposed to those requiring the player to stay in a singular location.SteamVR was first introduced for theOculus Riftheadset in 2014,and later expanded to support othervirtual reality headsets.Initially released for support on Windows, macOS, and Linux, Valve dropped macOS support for SteamVR in May 2020.SteamVR 2.0 was released in October 2023, introducing a new overlay interface that is unified with the updated SteamOS and Big Picture mode interfaces.

Storefront curation

Until 2012, Valve handpicked games to be included onto the Steam service, limiting these to games that either had a major developer supporting them, or smaller studios with proven track records. Since then, Valve have sought ways to enable more games to be offered through Steam, while pulling away from manually approving games, short of validating that a game runs on the platforms the publisher had indicated.In 2017, Steam development team member Alden Kroll said that Valve knows Steam is in a near-monopoly for game sales on personal computers, and the company does not want to be in a position to determine what gets sold, and thus had tried to find ways to make the process of adding games to Steam outside of their control.At the same time, Valve recognized that unfettered control of games in the service can lead to discovery problems as well as low-quality games.

Steam Greenlight

Valve announced Steam Greenlight to streamline game addition to the service in July 2012 and released the following month.Through Greenlight, Steam users would choose which games were added to the service. Developers were able to submit information about their games, as well as early builds or beta versions, for consideration by users. Users would pledge support for these games, and Valve would make top-pledged games available on Steam.In response to complaints during its first week that finding games to support was made difficult by a flood of inappropriate or false submissions,Valve required developers to payUS$100to list a game on the service. Those fees were donated to the charityChild's Play.This fee was met with some concern from smaller developers, who often are already working in a deficit and may not have the money to cover such fees.A later modification allowed developers to put conceptual ideas on the Greenlight service to garner interest in potential projects free-of-charge; votes from such projects are visible only to the developer.Valve also allowed non-gaming software to be voted onto the service through Greenlight.

The initial process offered by Greenlight was panned by developers because while they favored the concept, the rate of games that were eventually approved were small.In January 2013, Newell stated that Valve recognized that its role in Greenlight was perceived as a bottleneck, something the company was planning to eliminate in the future through an open marketplace infrastructure.On the eve of Greenlight's first anniversary, Valve simultaneously approved 100 games to demonstrate this change of direction.

Steam Direct

Valve launched Steam Direct on June 13, 2017, following Greenlight's shutdown the week before.With Steam Direct, a developer or publisher wishing to distribute their game on Steam needs only to complete appropriate identification and tax forms for Valve and then pay a recoupable application fee for each game they intend to publish. Once they apply, a developer must wait thirty days before publishing the game to allow Valve to review the game to ensure it is "configured correctly, matches the description provided on the store page, and doesn't contain malicious content".

On announcing its plans for Steam Direct, Valve suggested the fee would be in the range of $100–5,000, meant to encourage earnest software submissions to the service and weed out poor quality games that are treated asshovelware,improving the discovery pipeline to Steam's customers.Smaller developers raised concerns about the Direct fee harming them, and excluding potentially good indie games from reaching the Steam store.Valve opted to set the Direct fee at $100 after reviewing concerns from the community and outlined plans to improve their discovery algorithms and inject more human involvement to help these.Valve refunds the fee should the game exceed $1,000 in sales.In the process of transitioning from Greenlight to Direct, Valve mass-approved most of the 3,400 remaining games that were still in Greenlight, though the company noted that not all of these were at a state to be published. Valve anticipated that the volume of new games added to the service would further increase with Direct in place.Some groups, such as publisherRaw Furyand crowdfunding/investment siteFig,have offered to pay the Direct fee for indie developers who cannot afford it.VentureBeatcompared the system to theGoogle Play Store.

Games discovery changes

Without more direct interaction in the curation process, Valve had looked to find methods to allow players to find games they would be more likely to buy based on previous purchase patterns.Valve has rejected the use of paid advertising or placement on the storefront, which would have created a "pay to win" scenario. Instead, the company had relied on algorithms and other automatic features for game discovery, which has allowed for unexpected hits to gain more visibility.

The September 2014 "Discovery Update" added tools that would allow existing Steam users to be curators for game recommendations, and sorting functions that presented more popular games and recommended games specific to the user.This Discovery update was considered successful by Valve, as they reported in March 2015 in seeing increased use of the Steam Storefront and an increase in 18% of sales by revenue from just prior to the update.A second Discovery update was released November 2016, giving users more control over what games they want to see or ignore within the Steam Store, alongside tools for developers and publishers to better customize and present their game.

By February 2017, Valve reported that with the second Discovery update, the number of games shown to users via the store's front page increased by 42%, with more conversions into sales from that viewership. In 2016, more games are meeting a rough metric of success defined by Valve as selling more than $200,000 in revenues in its first 90 days of release.Valve added a "Curator Connect" program in December 2017. Curators can set up descriptors for the type of games they are interested in, preferred languages, and other tags along with social media profiles, while developers can find and reach out to specific curators from this information, and, after review, provide them directly with access to their game. This step, which eliminates the use of a Steam redemption key, is aimed at reducing the reselling of keys, as well as dissuading users who may be trying to game the curator system to obtain free game keys.

Valve has attempted to deal with "fake games", those that are built around reused assets and little other innovation, by adding Steam Explorers atop its existing Steam Curator program. Any Steam user can sign up to be an Explorer and be asked to look at under-performing games on the service to either vouch that the game is truly original or if it is an example of a "fake game", at which point Valve can take action to remove the game.

In July 2019, the Steam Labs feature was introduced as a means to showcase experimental discovery features Valve considered for including into Steam, to seek public feedback. For example, an initial experiment released at launch was the Interactive Recommender, which usesartificial intelligencealgorithms pulling data from the user's past gameplay history to suggest new games that may be of interest to them.As these experiments mature through end-user testing, they have then been brought into the storefront as direct features.

The September 2019 Discovery update, which Valve claimed would improve the visibility of niche and lesser-known games, was met with criticism from some indie game developers, who recorded a significant drop in the exposure of their games, including new wishlist additions and appearances in the "More Like This" and "Discovery queue" sections of the store.

Steam Charts were introduced in September 2022 and publicly track the storefront's best-selling and most-played games, including historically by week and month. Charts replaced a previous statistics page to be more comprehensive, and features content that had previously been part of third-party websites includingSteamSpy,SteamDB, and SteamCharts.

Games and account policies

In June 2015, Valve created a formal process to allow purchasers to request refunds, with refunds guaranteed within the first two weeks as long as the player had not spent more than two hours in a game.Prior to June 2015, Valve had a no-refunds policy, but allowed them in certain circumstances, such as digital rights management issues or false advertising.

Games that are no longer available for sale for various reasons can still be downloaded and played by those who have already purchased these.

Quality control

With the launch of Steam Direct, effectively removing any curation of games by Valve prior to being published on Steam, there have been several incidents of published games that have attempted to mislead Steam users. Starting in June 2018, Valve has taken actions against games and developers that are "trolling"the system; in September 2018, Valve explicitly defined that trolls on Steam" aren't actually interested ingood faithefforts to make and sell games to you or anyone ".As an example, Valve's Lombardi stated that the gameActive Shooter,which would have allowed the player to play as either a SWAT team member tasked to take down the shooter at a school shooting incident or as the shooter themselves, was an example of trolling, as he described it was "designed to do nothing but generate outrage and cause conflict through its existence".Within a month of clarifying its definition of trolling, Valve removed approximately 170 games from Steam.

In addition to removing bad actors, Valve has also taken steps to reduce the impact of "fake games" which could be used to manipulate the trading card marketplace or artificially boost a user's Steam level, in addition to changes in Steam to prevent such abuse.Some of these changes have resulted in selectfalse positivesfor legitimate games with unusual end-user usage patterns, such asWandersongwhich was flagged in January 2019 for what the developer believed was related to near-unanimous positive user reviews from the game.

Other actions taken by developers against the terms of service or other policies have prompted Valve to remove games,which has includedasset flips,review manipulation,misuse of Steamworks tools,and hostile activities towards Steam users.

Valve has banned games that incorporateblockchain-type technologies, such asnon-fungible tokens(NFTs) since 2022 due to the questionable nature of their markets. With the rise ofgenerative artificial intelligencein 2023, Valve originally established that games with content generated in this manner could be distributed through Steam, though cautioned developers about assuring that they had the rights for this type of content.As greater concerns about the copyright and ethical nature of generational AI in the latter half of 2023, Valve clarified its stance in January 2024, requiring games that did use content from generational AI to disclose this on the game's store page, including methods that the developers used to assure the AI engines did not generate illegal content.Valve updated policies in February to ban games that encorporated paid advertising as part of the gameplay cycle, such as viewing an ad for virtual rewards.

Mature content and moderation

Valve has also removed or threatened to remove games due to inappropriate or mature content, though there was often confusion as to what material qualified for this. For example, Eek Games'House Partyincluded scenes of nudity and sexual encounters in its original release, which drew criticism from conservative religious organizationNational Center on Sexual Exploitation,leading Valve to remove the title. Eek Games later included censor bars within the game, allowing the game to be added back to Steam, though they offered a patch on their website to remove the bars.In May 2018, several developers of anime-stylized games that contained some light nudity, such asHuniePop,were told by Valve they had to address sexual content within their games or face removal from Steam, leading to questions of inconsistent application of Valve's policies. The National Center on Sexual Exploitation took credit for convincing Valve to target these games. However, Valve later rescinded its orders, allowing these games to remain.

In June 2018, Valve clarified its policy on content, taking a more hands-off approach outside of illegal material. Rather than trying to make decisions themselves on what content is appropriate, Valve enhanced its filtering system to allow developers and publishers to indicate and justify the types of mature content (violence, nudity, and sexual content) in their games. Users can block games that are marked with this type of content from appearing in the store, and if they have not blocked it, they are presented with the description before they can continue to the store page. Developers and publishers with existing games on Steam have been strongly encouraged to complete these forms for these games, while Valve will use moderators to make sure new games are appropriately marked.Valve also committed to developing anti-harassment tools to support developers who may find their game amid controversy.

"So we ended up going back to one of the principles in the forefront of our minds when we started Steam, and more recently as we worked on Steam Direct to open up the Store to many more developers: Valve shouldn't be the ones deciding this. If you're a player, we shouldn't be choosing for you what content you can or can't buy. If you're a developer, we shouldn't be choosing what content you're allowed to create. Those choices should be yours to make. Our role should be to provide systems and tools to support your efforts to make these choices for yourself, and to help you do it in a way that makes you feel comfortable."

— Erik Johnson of Valve

Until these tools were in place, some adult-themed games were delayed for release.Negligee: Love Storiesdeveloped by Dharker Studios was one of the first sexually explicit games to be offered after the introduction of the tools in September 2018. Dharker noted in discussions with Valve that they would be liable for any content-related fines or penalties that countries may place on Valve, a clause of their publishing contract for Steam, and took steps to restrict sale of the game in over 20 regions.Games that feature mature themes with primary characters that visually appear to be underaged, even if the game's narrative establishes them as adults, have been banned by Valve.

In March 2019, Valve faced pressure overRape Day,a planned game described as being adark comedyand power fantasy where the player would control a serial rapist amid a zombie apocalypse. Valve ultimately decided against offering the game on Steam, arguing that while it "[respects] developers' desire to express themselves", there were "costs and risks" associated with the game, and the developers had "chosen content matter and a way of representing it that makes it very difficult for us to help them [find an audience]".

TheAnti-defamation Leaguepublished a report in November 2024 accusing Valve of allowing the proliferation of hate and anti-semitic content generated by users and user groups, with over 40,000 groups identified to have names referring to such extreme views. SenatorMark Warnerfollowed with a letter to Valve, asking the company if they were following their published online content policies and to review the cases identified by the ADL.

Platforms, devices and regions

Valve introduced the Steam Hardware Survey in 2003 ahead of the release ofHalf-Life 2.At that time, no information was available as to the distribution of CPU and GPU units among gamers, so Valve used the survey, which automatically collected hardware information with the user's permission through the Steam client, to collect this information and refine the hardware targets forHalf-Life 2to meet the widest possible specifications. Since then, Valve continues to use the Steam Hardware Survey to collect hardware distribution information, sharing the net results with other developers to understand the current market, as well as to make choices on when to discontinue support for older hardware and software.

Windows

Steam was originally released exclusively forMicrosoft Windowsin 2003, but has since been ported to other platforms.More recent Steam client versions use theChromium Embedded Framework.To take advantage of some of its features for newer interface elements, Steam uses64-bit versionsof Chromium, which makes it unsupported on older operating systems such asWindows XPandWindows Vista.Steam on Windows also relies on some security features built into later versions of Windows. Support for XP and Vista was dropped in 2019. While users still on those operating systems can use the client, they do not have access to newer features. Around 0.2% of Steam users were affected by this when it began.In March 2023, Valve announced that Steam would drop support forWindows 7and8on January 1, 2024.

macOS

Valve announced a client formacOSin March 2010.The announcement was preceded by a change in the Steam beta client to support the cross-platformWebKitweb browser rendering engine instead of theTrident engineofInternet Explorer.Valve teased the release by emailing several images to Mac community and gaming websites; the images featured characters from Valve games withApplelogos and parodies of vintageMacintoshadvertisements.Valve developed a full video homage to Apple's1984Macintosh commercial to announce the availability ofHalf-Life 2on the service; some concept images for the video had previously been used to tease the Mac Steam client.

Steam for macOS was originally planned for release in April 2010 before being pushed back to May 12, 2010. In addition to the Steam client, several features were made available to developers, allowing them to take advantage of the cross-platform Source engine and Steamworks' platform and network capabilities.Through the Steam Play functionality, the macOS client allows players who have purchased compatible products in the Windows version to download the Mac versions at no cost.The Steam Cloud, along with many multiplayer PC games, also supportscross-platform play.

Linux

In July 2012, Valve announced that it was developing a client for Linux based on theUbuntudistribution.This announcement followed months of speculation, primarily from the websitePhoronixthat had discovered evidence of Linux developing in recent builds of Steam and other Valve games.Newell stated that getting Steam and games to work on Linux is a key strategy for Valve; Newell called the closed nature ofMicrosoft Windows 8"a catastrophe for everyone in the PC space", and that Linux would maintain "the openness of the platform".Valve is extending support to any developers that want to bring their games to Linux, by "making it as easy as possible for anybody who's engaged with us—putting their games on Steam and getting those running on Linux", according to Newell.

The team developing the Linux client had been working for a year before the announcement to validate that such a port would be possible.As of the official announcement, a near-feature-complete Steam client for Linux had been developed and successfully run on Ubuntu.Internalbeta testingof the Linux client started in October 2012; external beta testing occurred in early November the same year.Open beta clients for Linux were made available in late December 2012,and the client was officially released in mid-February 2013.At the time of announcement, Valve's Linux division assured that its first game on the OS,Left 4 Dead 2,would run at an acceptable frame rate and with a degree of connectivity with the Windows and Mac OS X versions. From there, it began working on porting other games to Ubuntu and expanding to other Linux distributions.Versions of Steam working underFedoraandRed Hat Enterprise Linuxwere released by October 2013.There were over 500 Linux-compatible games on Steam in June 2014,and in February 2019, Steam for Linux had 5,800 native games and was described as having "the power to keep Linux [gaming] alive" byEngadget.

In August 2018, Valve released a beta version ofProton(namedSteam Play), an open-source Windows compatibility layer for Linux, so that Linux users could run Windows games directly through Steam for Linux. Proton comprises a set of open-source tools includingWineandDXVK.The software allows the use of Steam-supported controllers, even those not compatible with Windows.Released in February 2022, Valve's handheld computer, theSteam Deck,runs SteamOS 3.0 which is based on theArch Linuxdistribution and uses Proton to support Windows-based games without native Linux ports.Valve worked with various middleware developers to make sure their tools were compatible with Proton on Linux and maximize the number of games that the Steam Deck would support. This included working with various anti-cheat developers such as Easy Anti-Cheat andBattlEyeto make sure their solutions worked with Proton.To help with compatibility, Valve developed a classification system that they will populate to rank any game as to how well it works as a Linux native solution or through Proton.

Support forNvidia's proprietarydeep learning super sampling(DLSS) on supported video cards and games was added to Proton in June 2021, though this is not available on the Steam Deck which is based on AMD hardware.

In March 2022, Google offered a prerelease version of Steam onChromebooks,and entered public beta in November 2022.

Steamworks on consoles

AtE3 2010,Newell announced that Steamworks would arrive on thePlayStation 3withPortal 2.Steamworks made its debut onconsoleswithPortal 2'sPlayStation 3 release. Several features—including cross-platform play andinstant messaging,Steam Cloud for saved games, and the ability for PS3 owners to downloadPortal 2from Steam (Windows and Mac)—were offered.Valve'sCounter-Strike: Global Offensivealso supports Steamworks and cross-platform features on the PlayStation 3, including using keyboard and mouse controls as an alternative to the gamepad.Valve said it "hope[s] to expand upon this foundation with more Steam features and functionality in DLC and future content releases".

The Xbox 360 does not have support for Steamworks. Newell said that they would have liked to bring the service to the console through the gameCounter-Strike: Global Offensive,but later said that cross-platform play would not be present in the final version of the game.Valve attributes the inability to use Steamworks on the Xbox 360 to limitations in the Xbox Live regulations of the ability to deliver patches and new content. Valve's Erik Johnson stated that Microsoft required new content on the console to be certified and validated before distribution, which would limit the usefulness of Steamworks' delivery approach.

Mobile apps

Valve released an official Steam client foriOSandAndroiddevices in late January 2012, following a short beta period.The application allows players to log into their accounts to browse the storefront, manage their games, and communicate with friends in the Steam community. The application also incorporates atwo-factor authenticationsystem that works with Steam Guard. Newell stated that the application was a strong request from Steam users and sees it as a means "to make [Steam] richer and more accessible for everyone".A mobile Steam client forWindows Phonedevices was released in June 2016.In May 2019, a mobile chat-only client for Steam was released under the name Steam Chat.

On May 14, 2018, a "Steam Link" app with remote play features was released in beta to allow users to stream games to Android phones, named after discontinued set-top boxSteam Link.It was also submitted to theiOSApp Store,but was denied byApple Inc.,who cited "business conflicts with app guidelines".Apple later clarified its rule at the followingApple Worldwide Developers Conferencein early June, in that iOS apps may not offer an app-like purchasing store, but does not restrict apps that provideremote desktop support.In response, Valve removed the ability to purchase games or other content through the app and resubmitted it for approval in June 2018, where it was accepted by Apple and allowed on their store in May 2019.

Steam-branded devices

Before 2013, industry analysts believed that Valve was developing hardware and tuning features of Steam with apparent use on its own hardware. These computers were pre-emptively dubbed as "Steam Boxes" by the gaming community and expected to be a dedicated machine focused on Steam functionality and maintaining the core functionality of a traditional video game console.In September 2013, Valve unveiledSteamOS,a customLinux-based operating system they had developed specifically aimed for running Steam and games, and the final concept of theSteam Machinehardware.Unlike other consoles, the Steam Machine does not have set hardware; its technology is implemented at the discretion of the manufacturer and is fully customizable, much like a personal computer.In 2018 the Steam Machines were removed from the storefront due to low sales and small user traffic.

In November 2015, Valve released theset-top boxSteam LinkandSteam Controller(which was discontinued in 2019).The Steam Link removed the need for HDMI cables for displaying a PC's screen and allowed for wireless connection when connecting to aTV.That was discontinued in 2018, but now "Steam Link" refers to the Remote Play mobile app that allows users to stream content, such as games, from a PC to a mobile device over a network.

Steam Deck

Valve released theSteam Deck,a handheld gaming computer running an updated version ofSteamOS,with initial shipments starting on February 25, 2022.The Deck is designed for the play of Steam games, but it can be placed into a separate dock that allows the Deck to output to an externaldisplay.The Deck was released on February 25, 2022.Among updates to Steam and SteamOS included better Proton layer support for Windows-based games, improved user interface features in the Steam client for the Steam Deck display, and adding Dynamic Cloud Saves to Steam to allow synchronizing saved games while a game is being played.Valve began marking all games on the service through a Steam Deck Validated program to indicate how compatible they were with the Steam Deck software.

Steam Cloud Play

Valve included beta support for Steam Cloud Play in May 2020 for developers to allow users to play games in their library which developers and publishers have opted to allow in acloud gamingservice. At launch, Steam Cloud Play only worked through Nvidia'sGeForce Nowservice and would link up to other cloud services in the future though whether Valve would run its own cloud gaming service was unclear.

Steam China

The Steam China launch event in August 2019 in Shanghai

Steam China Release Event (featuringWallpaper Engine)

China hasstrict regulations on video games and Internet use;however, access to Steam is allowed through China's governmental firewalls. Currently, a large portion of Steam users are from China. By November 2017, more than half of the Steam userbase was fluent in Chinese, an effect created by the large popularity ofDota 2andPlayerUnknown's Battlegroundsin the country,and several developers have reported that Chinese players make up close to 30% of the total players for their games.

Following a Chinese government-ordered temporary block of many of Steam's functions in December 2017,Valve andPerfect Worldannounced they would help to provide an officially sanctioned version of Steam that meets Chinese Internet requirements. Perfect World has worked with Valve before to help bringDota 2andCounter-Strike: Global Offensiveto the country through approved government processes.All games to be released on Steam China are expected to pass through the government approval process and meet other governmental requirements, such as requiring a Chinese company to run any game with an online presence.

The platform is known locally as "Steam Platform" (Chinese:Chưng khí bình đài;pinyin:Zhēngqì píngtái) and runs independently from the rest of Steam. It was made to comply withChina's strict regulations on video games.Valve does not plan to prevent Chinese users from accessing the global Steam platform and will try to assure that a player's cloud data remains usable between the two.The client launched as an open beta on February 9, 2021, with about 40 games available at launch.As of December 2021, only around 100 games that have been reviewed and licensed by the government are available through Steam China.

On December 25, 2021, reports emerged that Steam's global service was the target of a domain name system attack that prevented users in China from accessing its site. The Chinese governmentMinistry of Industry and Information Technology(MIIT) later confirmed that Chinese gamers would no longer be able to use Steam's global service as its international domain name has been designated as "illegal". The block has effectively locked all Chinese users out of games they had purchased through Steam's international service.In 2023, reports emerged that the Steam Store could be used as normal in China, while the Steam Community was still blocked.

Reception and impact

Steam's success has led to some criticism because it supported DRM and for being an effective monopoly.In 2012,Free Software FoundationfounderRichard Stallmancalled DRM using Steam on Linux "unethical", but still better than Windows.

Steam's customer service has been highly criticized, with users citing poor response times or lack of response. In March 2015, Valve was given a failing "F" grade from theBetter Business Bureaudue to a large number of complaints about Valve's handling of Steam, leading Valve's Erik Johnson to state that "we don't feel like our customer service support is where it needs to be right now".Johnson stated the company plans to better integrate customer support features into the Steam client and be more responsive.In May 2017, in addition to hiring more staff for customer service, Valve publicized pages that show the number and type of customer service requests it was handling over the last 90 days, with an average of 75,000 entered each day. Of those, requests for refunds were the largest segment, and which Valve could resolve within hours, followed by account security and recovery requests. Valve stated at this time that 98% of all service requests were processed within 24 hours of filing.

Users and revenue

In August 2011, Valve said Steam's revenue, estimated to be $1 billion in 2010, was comparable to that of its published games and that this makes the company "tremendously profitable."Valve reported that there were 125 million active accounts on Steam by the end of 2015.By August 2017, the company reported that there were 27 million new active accounts since January 2016, bringing the total number of active users to at least 150 million.Most accounts were from North America and Western Europe, with there being a significant growth in accounts from Asia around 2017, spurred by their work to help localize the client and make additional currency options available to purchasers.In September 2014, 1.4 million accounts belonged to Australian users; this grew to 2.2 million by October 2015.

Valve also considersconcurrent users– how many accounts were logged in at the same time – a key indicator of the success of the platform. By August 2017, Valve reported that they saw a peak of 14 million concurrent players, up from 8.4 million in 2015, with 33 million concurrent players each day and 67 million each month.By January 2018, the peak online count had reached 18.5 million, with over 47 milliondaily active users.During theCOVID-19 pandemicin 2020, in which a large proportion of the world's population wereat home,Steam saw a concurrent player count of over 23 million in March, along with several games seeing similar record-breaking concurrent counts.The highest concurrent player count reached 39.2 million by December 2024, in part from the combined releases ofMarvel RivalsandPath of Exile 2.

Sales and distribution

Steam has grown from seven games in 2004 to over 30,000 by 2019, with additional non-gaming products, such as creation software, DLC, and videos, numbering over 20,000.More than 50,000 games were on the service as of February 2021.The growth of games on Steam is attributed to changes in Valve's curation approach, which allows publishers to add games without Valve's direct involvement, and games supporting virtual reality technology.The addition of Greenlight and Direct has accelerated the number of games present on the service, with almost 40% of the 19,000 games on Steam by the end of 2017 having been released in 2017.Before Greenlight, Valve saw about five new games published each week. Greenlight expanded this to about seventy, and which doubled to one hundred and eighty week following the introduction of Direct.

Although Steam provides direct sales data to developers and publishers, it does not provide public sales data. In 2011, Valve's Jason Holtman stated that the company felt that such data was outdated for a digital market.Data that Valve does provide cannot be released without permission because of anon-disclosure agreement.

Developers and publishers have asked for some metrics of sales for games, to allow them to judge the potential success of a title by reviewing how similar games have performed. Algorithms that worked on publicly available data through user profiles to estimate sales data with some accuracy led to the creation of the websiteSteam Spyin 2015.Steam Spy was credited with being reasonably accurate, but in April 2018, Valve added new privacy settings that defaulted to hiding user game profiles, stating this was part of compliance with theGeneral Data Protection Regulation(GDPR) of theEuropean Union.The change broke the method by which Steam Spy had collected data, rendering it unusable.A few months later, another method had been developed using game achievements to estimate sales with similar accuracy, but Valve shortly changed the Steam API that reduced its functionality. Some have asserted that Valve used the GDPR change as a means to block methods of estimating sales,although Valve subsequently promised to provide tools to developers to help gain such insights that they say will be more accurate.In 2020,Simon Carlessrevised an approach originally proposed byMike Boxleiteras early as 2013, with Carless's method used to estimate sales based on the number of reviews it has on Steam based on a modified "Boxleiter number" used as a multiplication factor.

Competition and curation impact

The accessibility of publishing games on digital storefronts like Steam has been described as key to the popularity ofindie games.As these processes allow developers to publish games on Steam with minimal oversight from Valve, journalists have criticized Valve for lacking curation policies that make it difficult to find quality games among poorly produced games, sometimes called "shovelware".

Following the launch of Steam Direct, the video game industry was split on Valve's hands-off approach. Some praised Valve for favoring avoiding trying to be a moral adjudicator of content and letting consumers decide what content they want to see, while others felt that this would encourage developers to publish games that are purposely hateful, and that Valve's reliance on user-filters and algorithms may not succeed in blocking undesirable content. Some further criticized the decision based on the financial gain from avoiding blocking any game content, as Valve collects a cut from sales through Steam.TheNational Center on Sexual Exploitationdenounced the policy for avoiding corporate and social responsibility "in light of the rise of sexual violence and exploitation games being hosted on Steam".

Steam was estimated to have the largest share of the PCdigital distributionmarket in the 2010s.In 2013, sales via the Steam catalog are estimated to be between 50 and 75 percent of the total PC gaming market.In 2010 and 2013, with an increase in retail copies of majorgame publishersintegrating or requiring Steam, retailers and journalists referred to the service as amonopoly,which they claimed can be detrimental to the industry and that sector competition would yield positive results for consumers.Several developers also noted that Steam's influence on the PC gaming market is powerful and one that smaller developers cannot afford to ignore or not work with, but believe that Valve's corporate practices make it a type of "benevolent dictator".

Because of Valve's oversight of sales data, estimates of the market share that Steam has of the videogame market are difficult to compile.Stardock,developer of competing platformImpulse,estimated that Steam had a 70% share in 2009.In February 2011,Forbesreported that Steam sales constituted 50–70% of theUS$4 billionmarket for downloaded PC games and that Steam offered game producersgross marginsof 70% of the purchase price, compared with 30% at retail.

Steam has been criticized for its reported 30% cut on revenue with publishers from game sales, a value that is similar to other digital storefronts according toIGN.However, some critics have asserted that the share no longer scales with cheaper costs of serving data. A 2019Game Developers Conferencesurvey showed only 6% of the 400 respondents deemed the share justified.Epic Games'Tim Sweeneypostulated that Valve could reduce its cut to 8%, given thatcontent delivery networkcosts has dropped significantly.Other services have promoted their sites having a lower cut, including theEpic Games StoreandDiscord.

In November 2009, online retailersImpulse,Direct2DriveandGamersGaterefused to offerCall of Duty: Modern Warfare 2because it includes mandatory installation of Steamworks.Direct2Drive accused Steamworks of being a "trojan horse".Valve's business development director Jason Holtman replied Steamworks' features were chosen by developers and based on consumer wants and thatModern Warfare 2was one of Steam's "greatest sellers".In December 2010,MCV/Developreported that "keytraditionalretailers "would stop offering games that integrate Steam.

Legal disputes

Steam's predominance has led to Valve becoming involved in various legal cases. The lack of a formal refund policy led theAustralian Competition and Consumer Commission(ACCC) to sue Valve in September 2014 for violating Australian consumer laws that required stores to offer refunds for faulty or broken products.The ACCC won the lawsuit in March 2016, though recognizing Valve changed its policy in the interim.In December 2016, the court fined ValveA$3 million,as well as requiring Valve to include proper language for Australian consumers outlining their rights when purchasing games off of Steam.In January 2018, Valve filed for special leave to appeal the decision to theHigh Court of Australia,but the High Court dismissed this request.In September 2018, Valve's Steam refund policy was found to violate France's consumer laws, and it was fined€147,000and required to modify its refund policy.

In December 2015, the French consumer groupUFC-Que Choisirinitiated a lawsuit against Valve for several of its Steam policies that conflicted with French law, including the restriction onreselling of purchased games,which is legal within the European Union.In September 2019, theTribunal de grande instance de Parisfound that Valve's practice of preventing resales violated the EU’sInformation Society Directiveof 2001 and theComputer Programs Directiveof 2009, and required them to allow it in the future.The Interactive Software Federation of Europe (ISFE) issued a statement that the French court ruling goes against established EU case law related to digital copies and threatened to upend much of the digital distribution systems in Europe should it be upheld.

In August 2016,BT Groupfiled a lawsuit against Valve, stating that Steam's client infringed on four of its patents, which it said were used within Steam's Library, Chat, Messaging, and Broadcasting services.

In 2017, theEuropean Commissionbegan investigating Valve and five other publishers—Bandai Namco Entertainment,Capcom,Focus Home Interactive,Koch Media,andZeniMax Media—for anti-competitive practices, specifically the use ofgeo-blockingto prevent access to software within certain countries within the European Economic Area. Such practices would be against theDigital Single Marketinitiative set by the European Union.The French gaming trade group, Syndicat National du Jeu Vidéo, noted that geo-blocking was a necessary feature to hinder inappropriateproduct keyreselling.The Commission found, in January 2021, that Valve and co-defendants had violatedantitrustrules of the European Union, issued combined fines of€7.8 million,and determined that these companies may be further liable to lawsuits from affected consumers.Valve had chosen "not to cooperate," and was fined€1.6 million,the most of any of the defendants.

A January 2021 class-action lawsuit filed against Valve asserted that it forced developers into entering a "most favored nation"-type of pricing contract to offer games on their storefront, which required the developers to price their games the same on other platforms as they did on Steam, thus stifling competition.Gamasutra's Simon Carless analyzed the lawsuit and observed that Valve's terms only apply the resale of Steam keys and not games themselves, and thus the lawsuit may be without merit.

A separate class-action lawsuit filed against Valve byWolfire Gamesin April 2021 asserted that Steam is essentially a monopoly, since developers must sell to PC users through it and that its 30% cut and "most favored nation" pricing practices violate antitrust laws as a result of their position.Valve's response, filed in July 2021, dismissed the complaint stating that it "has no duty under antitrust law to allow developers to use free Steam Keys to undersell prices for the games they sell on Steam—or to provide Steam Keys at all". Valve defended its 30% revenue as meeting the currentIndustry standardand claimed Wolfire's figure Steam's market share to lack evidence.Wolfire's suit was dismissed by the presiding judge in November 2021 after determining that Wolfire had failed to show that Valve had a monopoly on game sales and that the 30% cut has remained unchanged throughout Valve's history.Wolfire refiled its case, narrowing the complaint to Valve's use of its dominance to intimidate developers that sell their game for less on other marketplaces, which the judge allowed to proceed in May 2022.According to discovery, Valve was ordered to have Gabe Newell submit to a deposition for discussion of Valve's business strategy related to Steam.

Valve changed the Steam terms of service in September 2024 to eliminate the forcedarbitration clause,such that any disputes with the storefront are to be resolved within courtrooms, and allowing for class-action lawsuits.
