The United Kingdom's Competition and Markets Authority (CMA) is challenging Microsoft and Activision Blizzard to justify their planned merger, saying the deal "could substantially lessen competition" in the gaming industry. A CMA announcement today cited concerns about "competition in gaming consoles, multi-game subscription services, and cloud gaming services (game streaming)."

Microsoft announced its plan to buy Activision Blizzard for $68.7 billion in January.
