Steam is an internet distribution platform for computer games, software, movies, series, and computing devices developed and operated by Valve Corporation. It recorded over one billion active user accounts in 2019, according to the manufacturer. About 47 million users use the platform every day (2018). In March 2020, it set a record of over 20 million concurrent users, including over 6 million active gamers.
The system enables online distribution, maintenance (patching) and rights management (DRM) of the games as well as communication among players, the formation of communities and the provision of publicly viewable player profiles. It was released for Windows on September 12, 2003. Valve's games, such as Half-Life or Counter-Strike, have since been updated exclusively via Steam. For games from this manufacturer, Steam is a prerequisite for installation and subsequent operation. The previous multiplayer platform World Opponent Network was shut down in August 2004. Since October 2005, an increasing number of games from other providers can also be purchased via the system.
Since October 2012, other software in addition to games has been distributed via Steam. To use purchased or free games or software from the platform, the Steam client is required, which can be downloaded as freeware under a proprietary license from the official site. However, the Steam Community and the Steam Shop can also be used via a conventional browser.
Since May 2010, Steam also supports macOS. At the beginning of March 2012, the Steam client was added as an app for Android and iOS. This version includes the mobile sending of direct messages as well as the receipt of the same via notifications, the purchase of software and games, and the access to the mobile version of the Steam Community. In addition, titles can also be added to the wishlist with this and the Steam credit can be extended via some methods. In addition, one can add two-factor authentication to their Steam account, which requires entering the access code generated in the app when logging into a computer. In February 2013, the official Linux version was released.
