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.
Tencent-owned gaming publisher of League of Legends and Valorant with 150M+ registered LoL accounts; competitive gaming pioneer generating $1.5-2B annually through cosmetic monetization and esports.
About
Riot Games is a Los Angeles-based game developer and publisher that transformed competitive gaming — best known for League of Legends (LoL), the world's most-played PC game by active players and the foundational title of the MOBA (multiplayer online battle arena) genre, alongside Valorant (tactical shooter), Teamfight Tactics (auto battler), Legends of Runeterra (digital card game), and Wild Rift (mobile LoL). Riot Games was acquired by Tencent (HKEX: 0700) in 2015 (full acquisition) and is wholly owned by Tencent, the world's largest gaming company, with estimates suggesting Riot generates $1.5-2 billion in annual revenue from game operations and esports.
