Microsoft shifted 1.4 million Xbox 360 units in the US during December, according to the latest NPD Group report.
The console remains a favourite in North America, with its top positioning unchallenged for 24 consecutive months. In total, Americans spent $1.27 billion on Xbox hardware, games and accessories.
According to Microsoft, the 1.4 million units more that doubled the units sold for the second ranking console. "We expect 2013 will be another big year for Xbox 360 and we're eager to continue to expand and grow the offerings available on the platform," the company said in a statement.
