Microsoft has confirmed the Xbox One sold over three million units worldwide during 2013.
"Since our launch, demand for Xbox One has been strong, selling out throughout the holidays at most retailers worldwide. We are continuing to work hard to deliver additional consoles to retailers as fast as possible," said Yusuf Mehdi, corporate VP of strategy and marketing for Xbox.
The system went on sale in November in the US and Europe and was available in 13 countries by the end of the year.
"It’s been incredible to see Xbox One selling at a record-setting pace for Xbox, and we were honoured to see Xbox One become the fastest-selling console in the U.S. during our launch month in November," he added.
