There's no bigger gaming franchise on the console than 'Call of Duty', and we can't wait to see what the community can create with this new tool.

A goal of Twitch is to be wherever gamers are, whether it's on laptops and handheld devices or integrated into gaming consoles and software.

I'm always impressed by how compassionate the gaming community can be when they have a cause and appreciate that they leverage our platform to raise money for those in need. We continue to encourage giving in support of important causes, including Extra Life 2012.

Given the huge number Xbox owners and how many of them love gaming spectatorship, it's a natural fit to bring the Twitch experience to the 360.

Twitch launched in June of 2011, and our growth ever since has exceeded even my expectations, which were not small. A year and a half later, the community of broadcasters and viewers has multiplied hundreds of percent.

The Twitch community loves watching video games, chatting, and broadcasting. The average viewer watches over an hour and a half of video each day. Over two-thirds of our logged-in users chat each day.
