Activision is known in the United States as the first "third-party" developer, getting its nose in the video game industry with games for the UsefulNotes/{{Atari2600}}, and co-founded by four former Atari designers (David Crane, Larry Kaplan, Bob Whitehead and Alan Miller). Against Atari's publishing policies at the time, Activision was the first studio to allow programmers to take credit for the games they designed.

Unlike many other companies developing games for second-generation consoles, Activision survived TheGreatVideoGameCrashOf1983 intact, being quick to jump on the UsefulNotes/{{Commodore 64}} bandwagon, and even added to its catalog several games from defunct competitor Imagic, whose advertising TagLine for their games was "Designed By Experts For Experts". Activision acquired Creator/{{Infocom}} in 1986.

In 2007, Activision became the single largest third-party game developer in the United States (after it merged with Vivendi Games (previously Creator/{{Universal}} Interactive before Universal Music and Interactive were split up before Universal's merger with NBC), the holding company of Creator/BlizzardEntertainment, best known for ''VideoGame/{{Warcraft}}'', ''Franchise/StarCraft'' and ''VideoGame/{{Diablo}}'' and thus becoming Activision Blizzard), surpassing Creator/ElectronicArts. Today, the company is best known for being the publisher of the ''VideoGame/CallOfDuty'' series and games by Creator/BlizzardEntertainment, kicking off the late 2000s music game fad with the ''VideoGame/GuitarHero'' series and for its controversial business practices, especially concerning the contractual dispute with ''VideoGame/CallOfDuty'' developer Infinity Ward.
