Call of Duty is one of the most profitable franchises in gaming. It's been that way for decades. And, while Activision Blizzard is on Microsoft's side right now as part of the ongoing $70 billion acquisition, there was a time when the two weren't quite on good terms.

Apparently, because of how much fewer Call of Duty players are on Xbox, Activision Blizzard had threatened Microsoft that it wouldn't put its Call of Duty games on the Xbox Series S/X if it didn't agree on a revised revenue cut.

This surprising revelation emerged as part of the ongoing trial between Microsoft and the US Federal Trade Commission, as transcribed by TweakTown.

According to Xbox's corporate vice president, Sarah Bond, Bobby Kotick, Activision's CEO, once played a high-stakes game of chicken with Microsoft ahead of the Xbox Series X/S launch a few years ago. Apparently, Kotick demanded a better cut from the traditional 70-30 revenue split model between platform holders and publishers, threatening to withhold Call of Duty from the new Xbox consoles.
