The Xbox One crossed more than one million consoles sold worldwide in less than 24 hours, making it the biggest Xbox launch in history, Microsoft announced.

The Xbox One is now sold out at most retailers in the 13 markets it's available in worldwide. Microsoft says it's working to replenish stock to meet demand.

“We are humbled and grateful for the excitement of Xbox fans around the world,” said Yusuf Mehdi, corporate VP of marketing and strategy for Xbox. “Seeing thousands of excited fans lined up to get their Xbox One and their love for gaming was truly a special moment for everyone on the Xbox team. We are working hard to create more Xbox One consoles and look forward to fulfilling holiday gift wishes this season.”
