Steam (steampowered.com) is the absolute, undisputed monopoly of PC gaming distribution. Operated by the highly secretive private company Valve, Steam functions as the digital library, social network, and storefront for hundreds of millions of PC gamers globally. Effortlessly securing its place among the top websites in the world, Steam fundamentally saved PC gaming from physical retail extinction and birthed the modern era of digital game ownership.
Steam was launched in September 2003 by Gabe Newell and the team at Valve Corporation in Bellevue, Washington. Initially, the platform wasn't even built to sell games; it was created out of necessity to silently deliver anti-cheat updates and software patches to their incredibly popular multiplayer shooter, Counter-Strike, without breaking the game. In 2004, Valve began negotiating with third-party publishers to sell their games on Steam. In the 2010s, frustrated by Microsoft's aggressive push to lock down the Windows 8 operating system, Gabe Newell famously called Windows a 'catastrophe' and heavily pivoted Steam toward Linux compatibility, laying the groundwork for the modern Steam Deck hardware.
Steam is the central nervous system for the global PC gaming community:
Because Valve is a strictly private company with no outside investors, its exact financial metrics are fiercely guarded. However, analysts estimate the Steam platform's standalone enterprise value at roughly $15 Billion. Steam operates as a highly lucrative tollbooth; it notoriously takes a standard 30% revenue cut of almost every single game, microtransaction, and DLC sold on the platform, allowing Valve to generate billions in pure profit without necessarily having to develop new video games themselves.
Generating 720 Million web visits per month, Steam is a universally trafficked hub. Because PC gaming is highly accessible globally, its traffic is remarkably decentralized. The United States accounts for 20% of its web traffic, closely followed by massive, highly dedicated PC gaming markets in Russia (10%), China (8%), Brazil, and Germany.
