About
Steam is the world's largest PC gaming distribution platform, developed and operated by Valve Corporation, which was founded in 1996 by former Microsoft employees Gabe Newell and Mike Harrington. Valve launched Steam in 2003 initially as a software update and anti-cheat delivery mechanism for its own titles, then rapidly evolved it into a full digital storefront and social platform. The underlying technology includes the Steam client, Steamworks SDK for developers, and Valve's proprietary content delivery network — infrastructure that handles one of the highest-volume software distribution workloads in the world.\n\nSteam offers a catalog of over 100,000 games from publishers and independent developers, with features including cloud save synchronization, in-game overlay, workshop mod support, Steam Workshop, family sharing, and an active marketplace for user-generated content and tradeable in-game items. The Steam Deck, Valve's Linux-based handheld gaming PC launched in 2022, extends the Steam ecosystem to portable hardware and has driven significant investment in Linux game compatibility through the Proton compatibility layer. Valve continues to publish original titles including the Half-Life, Portal, and Dota 2 franchises, which drive substantial platform engagement.\n\nSteam commands approximately 75% of PC game digital sales globally with 120 million+ monthly active users. Valve takes a 30% revenue cut on most sales (reduced to 20–25% for top-selling titles), generating estimated annual revenues exceeding $5B from a company that has never gone public and remains entirely privately held. The Steam Summer and Winter sales are among the most-anticipated events in gaming annually, driving industry-wide conversation and purchase behavior. Valve's refusal to discuss financials publicly has made it one of the most closely watched private technology companies in the games industry.
