CES: Over 39 million Xbox 360s sold worldwide, over $20bn spent

More than $20 billion has been spent on it since its 2005 retail launch and 500 million games have shifted from shelves to gamers.

Pretty impressive numbers there considering Microsoft was only 'that operating system company' a decade back. Ballmer also announced the 'Game Room', where Avatars get together and play retro games on both Xbox 360 and PC.
