Valve Software is a successful and influential games development company based in Bellevue, Washington. It was founded by former Microsoft employees Gabe Newell and Mike Harrington in 1996. Their first project was the highly acclaimed Half-Life, based on a Quake engine source code license they bought. After the release of Half-Life, Valve went on to make more successful games, building on their success with Half-Life by working on mods and related games, such as Team Fortress, Counter-Strike and Day of Defeat. In more recent times, they've upgraded many of their games to run on their new Source engine. All of their games are now released via their Steam content delivery system, which allows pre-purchasing and pre-loading of purchased games before they're released.
