Twitch is used by millions of gamers, who stream their gameplay over the internet and watch countless hours of others' content. The service is really incredibly successful, and it was positively ingenious of Microsoft to get it integrated into the Xbox One at the hardware level.

The details are still somewhat fuzzy, but we do know that Twitch streaming and Twitch accounts will be a big part of the Xbox One's offerings, and that's a master stroke for competitive gamers or those who simply like to watch others play. The PS4 has some similar functionality, but right now it looks like Microsoft will win in this area.
