HistoryEdit

Valve was founded by long-time Microsoft employees Gabe Newell and Mike Harrington on August 24, 1996[2][3] as an L.L.C. based in Kirkland, Washington.

After the success of Half-Life, the team worked on mods, spin-offs, and sequels, including Half-Life 2. All current Valve games are built on its Source engine, which owes much of its success to mods and sequels. The company has developed six game series: Half-Life, Team Fortress, Portal, Counter-Strike, Left 4 Dead and Day of Defeat. Valve is noted for its support of its games' modding community: most prominently, Counter-Strike, Team Fortress, and Day of Defeat. Valve has branched out with this tradition to continue developing the Warcraft III-based mod Defense of the Ancients with Dota 2.[5] Each of these games began as a third-party mod that Valve purchased and developed into a full game. They also distribute community mods on Steam.

Since Valve Corporation's debut, it has expanded both in scope and commercial value. On January 10, 2008, Valve Corporation announced the acquisition of Turtle Rock Studios.[6] On April 8, 2010, Valve won The Escapist Magazine's March Mayhem tournament for the best developer of 2010.[7] They beat Bioware in the finale and Zynga in the semi-final.
