Microsoft's bid to acquire the "Call of Duty" videogame maker was approved by the European Union in May, but British competition authorities blocked the takeover in April. The FTC has argued that the deal, which would be the largest for Microsoft and the biggest in the history of the video game business, would give Microsoft the "ability and increased incentive to withhold or degrade Activision's content in ways that substantially lessen competition." In addition, the FTC says the combination would give Microsoft's Xbox video-game console exclusive access to Activision games, leaving Nintendo consoles and Sony Group Corp's PlayStation out in the cold. Microsoft has said that the deal would benefit gamers and gaming companies alike, and it has offered to sign a legally binding consent decree with the FTC to provide "Call of Duty" games to rivals for a decade. The hearing is scheduled to proceed through June 29.
