The UK competition regulator announced the launch of an antitrust investigation into Microsoft's proposed $68.7 billion acquisition of video gaming giant Activision Blizzard.
The probe into what would be Microsoft's biggest acquisition in its history will focus on whether the deal may substantially lessen competition — or create expectations that it might.
Microsoft has previously said it expects antitrust officials to scrutinize how the deal, announced in January, may affect competition in the video game industry, app stores, and even labor markets.
