Microsoft has been touting the success of its online Xbox gaming service at the Consumer Electronics Show, (CES), in Las Vegas.
"We have been amazed at the results of Xbox Live," said Bill Gates in his speech at the start of the event. "Sales of the starter kits have been doubled our original projections."
Xbox officials are promising a raft of new games in the coming year to rival the best titles currently on sale.
Microsoft is investing millions into fostering a network of gamers across the world, playing against each other on the Xbox.
Mr Gates joined in the marketing push at CES, hooking up with basketball star Shaquille O"Neal in Los Angeles to play a racing game live.
