Marc Whitten, the chief product officer of Xbox, has left Microsoft after 14 years with the company. Whitten helped to launch all three Xbox systems, from the original console back in 2001 to the Xbox One last year, and is now taking up the same role of chief product officer at wireless audio company Sonos. Beyond Whittens new position, Microsoft gave no reason for the departure, and there may not be a direct replacement — Whittens remaining team will report to Terry Myerson, who took over Windows, Windows Phone, and Xbox software last year.
