Valve Corporation
American video game development and digital distribution company

Valve Corporation, also known as Valve Software, is an American video game developer, publisher, hardware, and digital distribution company headquartered in Bellevue, Washington. It is the developer of game franchises including Half-Life, Counter-Strike, Portal, Team Fortress, Left 4 Dead and Dota, the software service Steam, and hardware including the Steam Frame, Steam Machine, Steam Deck and Valve Index.
Valve was founded in 1996 by former Microsoft employees Gabe Newell and Mike Harrington. Their debut game, the first-person shooter (FPS) Half-Life (1998), was a critical and commercial success that had a lasting influence on the genre. Harrington left in 2000. In 2003, Valve launched Steam, followed by Half-Life 2 (2004), the episodic sequels Half-Life 2: Episode One (2006) and Episode Two (2007), the puzzle games Portal (2007) and Portal 2 (2011), and the multiplayer games Team Fortress 2 (2007), Left 4 Dead (2008), and Dota 2 (2013).
During the 2010s, Valve released fewer games and focused on hardware and virtual reality (VR). They released the first Steam Machine console in 2015, the Valve Index VR headset in 2019, their flagship VR game, Half-Life: Alyx, in 2020, and the handheld system Steam Deck in 2022. In 2026, Valve released a redesigned Steam Machine and a standalone VR headset, the Steam Frame.
Valve uses a flat organizational structure, allowing employees to choose their own projects.
This brief starts where responsible research should: with the source description of “Valve Corporation” as american video game development and digital distribution company. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as american video game development and digital distribution company. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q193559. VIAF identifies the subject as 147977846. The Library of Congress control number is nr2004037172. 2 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1996, 1998, 2000 and 2003.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
