Twitch is a platform that allows gamers to live stream themselves playing and chat with viewers. It started in 2007 as Justin.tv by a group of people known by names as Kyle Vogt, Michael Seibel, Justin Kan, and Emmett Shear.
Justin.tv featured the life of Justine on a live stream. He had a camera attached to his cap and backpack. When the team realized people were interested in this, they developed a platform that drew more traffic. The team founded Twitch in 2011 without knowing how to monetize the platform.
