FTC will try to prevent Microsoft from buying Activision Blizzard. According to people familiar with the matter, the Federal Trade Commission (FTC) plans to sue Microsoft in federal court on Monday local time to prevent the company from completing the $69 billion acquisition of Activision Blizzard. FTC plans to seek a court order to block the deal until the internal court of the agency has the opportunity to rule on the deal, the source said. The trial in the FTC Internal Court is scheduled to begin in August.
