Microsoft has officially completed its acquisition of video game publisher Activision Blizzard. This is Microsoft's largest deal to date and gives them access to popular game franchises such as Call of Duty and Diablo. The acquisition was delayed due to regulatory concerns from the U.S., European, and U.K. authorities, but Microsoft made concessions to address these concerns. Activision Blizzard CEO Bobby Kotick will remain in his position until the end of the year, and Microsoft Gaming CEO Phil Spencer has expressed plans to bring these franchises to platforms like Game Pass. The Federal Trade Commission still has concerns about the deal.
