Twitch

Twitch is an American live streaming video service operated by Twitch Interactive, a subsidiary of Amazon.com. The site primarily focuses on video game live-streaming, including broadcasts of eSports competitions, in addition to music broadcasts, creative content, and "in real life" (IRL) streams. It was introduced in June 2011 as a spin-off of the general-interest streaming platform Justin.tv. Content on the site can be viewed live or via video on demand.

The popularity of Twitch eclipsed that of its general-interest counterpart Justin.tv. In October 2013, the website had 45 million unique viewers. By February 2014, the parent company of Justin.tv was rebranded as Twitch Interactive to represent the shift in focus, and Justin.tv was shut down in August 2014. That same month, the service was acquired by Amazon for US$970 million.
