FTC Investigates Microsoft's Gaming Deals with Nintendo and Sony.

The Federal Trade Commission has subpoenaed Steve Singer, Nintendo of America's vice president of publisher and developer relations, to testify about the 10-year Call of Duty licensing deal that Microsoft and Nintendo signed. The FTC is investigating the deal as part of its antitrust lawsuit against the Microsoft-Activision merger. The subpoena was served after the deadline, and Nintendo has asked for it to be quashed. The FTC's interest in the deal's details is unclear, but it may be related to Sony's complaints about the deals. The FTC has also removed Nintendo from the relevant market in the case, causing confusion in Congress and the Senate Finance Committee.
