CES: 20 million people now using Live, says Bach

Over 20 million people are now using Xbox Live worldwide, Microsoft confirmed at its CES keynote last night.

The news came from the company's head of Entertainment & Devices division, Robbie Bach.

"Today, over 20 million people are Xbox Live members," he said.

"To put this in context and perspective, that's nearly three times the number of people who watch Oprah."

Earlier in the keynote, Microsoft president Steve Ballmer said that over 39 million Xbox 360s had been sold worldwide since the machine's launch back in winter 2005.
