Definition
The pioneering live streaming platform founded in 2007 by Justin Kan and Emmett Shear that served as the direct predecessor to Twitch. JustinTV began as a single-channel 24/7 life-streaming experiment by Justin Kan and evolved into a multi-channel platform that enabled anyone to broadcast live video. In 2011, JustinTV spun off its gaming-focused section as Twitch.tv, and in 2014 the parent company was rebranded entirely as Twitch after Amazon's $970 million acquisition. JustinTV is historically significant as the platform that proved the commercial viability of live streaming as a creator medium.
