Over five years after the Xbox 360 launched in November 2005, the console powered through the 2010 holiday season — racking up its biggest sales month ever and capping off the biggest year in the console’s history. Microsoft sold 1.9 million Xbox 360 units in December according to NPD Group, providing more icing on Microsoft’s gaming cake following news that the company sold over 8 million Kinect sensors in 60 days. Year-over-year growth came in at 42%, making Xbox the fastest-growing console in 2010. NPD also says consumers spent more money on Xbox 360 than any other game console in 2010 — a whopping $6.2 billion. The top three games for Xbox in 2010 were Call of Duty: Black Ops, Assassin’s Creed Brotherhood and Kinect Sports.
