Justin.tv is a website that allows users to produce and watch live streaming video. Like YouTube, Justin.tv user accounts are called "channels", and users are encouraged to broadcast a wide variety of user-generated live video content, called "broadcasts".
The company is an Internet startup based in San Francisco, California, with seed funding from Paul Graham of seed capital firm Y Combinator and Series A funding with Alsop Louie Partners and Draper Associates
Justin.tv is notable for its origin: The original Justin.tv was a single channel featuring founder Justin Kan, who broadcast his life 24/7 and popularized the term lifecasting. In 2007, Justin Kan stopped broadcasting and Justin.tv relaunched into its current form as a network of thousands of various channels.
Users are permitted to broadcast to an unlimited number of people for free, and watching broadcasts do not require user registration. Broadcasts that are considered to contain potentially offensive content are available only to registered users over the age of 18. Broadcasts containing defamation, pornography, copyright violations, and material encouraging criminal conduct is prohibited by Justin.tv's terms of service.
