Microsoft sold more than three million Xbox One units by the end of 2013 globally, the firm has said.
"Over 3 million Xbox One consoles were sold to consumers in 13 countries before the end of 2013," said Xbox corporate VP of marketing, strategy and business, Yusuf Mehdi, in a statement thanking players for their support.
"With Xbox One we saw the most epic launch for Xbox by all measures. We are humbled and grateful for your loyalty and delighted by the millions of hours of gameplay and entertainment enjoyed on Xbox," Mehdi added.
"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.
"We also love that you are seeing the promise of an all-in-one entertainment system. Millions of hours of live TV have been watched and millions of hours of app entertainment have been enjoyed."
Microsoft had sold two million Xbox One systems globally in 18 days following its launch in 13 markets on November 20, which included US, Canada, UK and mainland Europe, Brazil, Australia, New Zealand and more.
By comparison, PS4 reached 2.1 million units after 14 days on sale in North America alone, since the system launched in Europe two weeks after its NA debut.
