Steam is a digital distribution service and storefront developed by Valve Corporation. It was launched as a software client in September 2003 to provide video game updates automatically for Valve's games and expanded to distributing third-party titles in late 2005. Steam offers various features, such as game server matchmaking with Valve Anti-Cheat measures, social networking, and game streaming services. The Steam client functions include update maintenance, cloud storage, and community features such as direct messaging, an in-game overlay, discussion forums, and a virtual collectable marketplace. The storefront also offers productivity software, game soundtracks, videos, and sells hardware made by Valve, such as the Valve Index and the Steam Deck. Steamworks, an application programming interface released in 2008, is used by developers to integrate Steam's functions, including digital rights management, into their products.
