Steam can be a digital distribution platform manufactured by Valve Corporation offering digital rights management (DRM), multiplayer gaming and social networking services. Steam supplies the user with installation and automatic updating of games on multiple computers, and community features for example friends lists and groups, cloud saving, and in-game voice and chat functionality. The software gives a freely available application programming interface (API) called Steamworks, which developers are able to use to integrate a lot of Steam's functions to their products, including networking, matchmaking, in-game achievements, micro-transactions, and support for user-created content through Steam Workshop.
Though initially created for experience Microsoft Windows, versions for OS X and Linux operating systems were later released. Applications whose main functions are chatting and shopping seemed to be released for iOS, Android and Windows Phone mobile phones. The Steam website also replicates most of the storefront and social network features of the stand-alone application.
