Mattrick is largely to thank for the bestselling video game console of this long-running generation, the Xbox 360. When he first arrived from Electronic Arts to Microsoft in back in 2007, things weren't well. But Mattrick turned things around with a three-year plan to streamline the business. Mattrick also assembled the team and recruited the talent behind Kinect, the company's motion-sensor controller for the Xbox 360 that has since become one of the most popular consumer products in recent history.
