For the year, Xbox 360 platform revenue grew $2.7 billion or 48%, thanks to "increased volumes of Xbox 360 consoles, sales of Kinect sensors, and higher Xbox Live revenue." Microsoft shipped 13.7 million consoles during fiscal '11 versus 10.3 million in fiscal '10. That success has propelled revenue growth at the entire Entertainment & Devices Division 30% for Q4 and 45% for the year (nice going, Windows Phone 7). Revenues for all of Microsoft were up 8% for the period, year-over-year, with the company singling out "the Xbox 360 entertainment platform" as one of the primary catalysts for growth.
With the top-selling home console in North America for 12 of the last 13 months, according to NPD data, and a runaway hit in Kinect, it's easy to see why Xbox 360 is doing so well for Microsoft.
