There have been 67 million Xbox 360s sold around the world, and 19 million Kinects, Microsoft has revealed.
Microsoft's chief Xbox marketing officer Yusuf Mehdi revealed the numbers in a company blog post.
Microsoft's latest financial reports revealed life-to-date sales of 67.2 million for Xbox 360. Kinect numbers weren't mentioned.
"To date, our success with Xbox has been led by a box in the living room," wrote Mehdi. "Moving forward, Xbox will go beyond the box to reach all new families of devices. Just as Xbox has grown to mean more than just games, it also is more than just a console.
"This year, Xbox becomes the premium entertainment service for Microsoft. Whether on your PC, tablet, TV or phone, Xbox will be a gateway to the best in music and video, your favourite games and instant access to your friends.
"With the launch of Windows 8, we'll bring Xbox entertainment to everyone. With Xbox on Windows 8 devices, we rapidly accelerate the reach of Xbox entertainment from more than 60 million people to hundreds of millions of people worldwide."
Mehdi said Microsoft had "ideas for making all the entertainment you love more personal, interactive and social across the devices you love - and on the phenomenal Windows 8 devices that are to come".
