Justin.tv was a website that allowed anyone to broadcast video online. Justin.tv user accounts were called channels, and users were encouraged to broadcast a wide variety of user-generated live video content, called broadcasts. Users were permitted to broadcast to an unlimited number of people for free, and watching broadcasts did not require user registration. Broadcasts that were considered to contain potentially offensive content were available only to registered users over the age of 18. Broadcasts containing defamation, pornography, copyright violations, or encouraging criminal conduct were prohibited by Justin.tv's terms of service.
