Microsoft recently reported that their Entertainment & Devices division (which primarily generates revenue from the Xbox 360 and related businesses) saw an increase in revenue by 55 percent to $3.7 billion. This includes a 6.3 million Xbox 360 consoles sold over the holidays, up 21 percent, and perhaps most significantly 8 million Kinect sensors sold.

Peter Klein, chief financial officer for Microsoft, proclaimed in a conference call that Kinect is the fastest-selling consumer electronics device in history.
