Activision Blizzard is an American video game company based in California. 

Founded in 2008 when Activision merged with Vivendi games, the company is made up of Activision Publishing, King, Blizzard Entertainment, Major League Gaming, and Activision Blizzard Studios. 

It is currently in the process of being bought out by Xbox owner Microsoft, but the $68.7 billion deal is being looked at by anti-competitive authorities around the world. 

The company is best known for its developers Treyarch and Infinity Ward, creators of the Call of Duty series. Activision Blizzard also publishes World of Warcraft, Overwatch 2, Diablo, StarCraft, Heroes of the Storm, Tony Hawk's, Crash Bandicoot, Spyro, Hearthstone, Candy Crush Saga, and more. 

Bobby Kotick has headed up Activision Blizzard since its conception in 2008, but he has been embroiled in controversy in recent years, with allegations of workplace misconduct.
