Bobby Kotick, the longtime CEO of Activision Blizzard, is stepping down Dec. 29 following the company’s drawn-out $69 billion sale to Microsoft that closed in October. The exec — who oversaw some of the industry’s most popular games from Pitfall to Call of Duty, World of Warcraft, Overwatch, Candy Crush Saga and Farm Heroes Saga — had said previously he would stay on through the end of 2023.
