Microsoft has sold two million Xbox One systems in the space of 18 days since its launch on November 20, the corporation said in a statement today.
It is the first indication that Sony's PlayStation 4 is outselling the console globally, either due to better supply or heightened demand. PS4 reached 2.1 million units after 14 days, with the system launching in Europe two weeks after North America.
Nevertheless, the two million sales milestone was described by Microsoft as a company record.
"We continue to be humbled and overwhelmed by the positive response from our fans. We are thrilled to see sales of Xbox One on a record-setting pace, with over 2 million Xbox One consoles in homes around the world," said Yusuf Mehdi, the corporate vice president of strategy and marketing at Xbox.
He went on to suggest that it is production yields that are holding sales back.
"Demand is exceeding supply in our 13 launch markets and Xbox One is sold out at most retailers," he claimed.
"We're also particularly excited to see consumers engaging in a wide range of games and entertainment experiences on the platform, with more than 1 million paid transactions on Xbox Live to date".
On Thursday, sales vendor NPD will have the first opportunity to disclose details of how well the PS4 and Xbox One have been selling across North America. Yet at launch phase, system sales numbers may not tell the whole story as supply constraints can dictate the numbers as much as demand does.
