Valve accidentally “launched” its Twitch competitor Steam.tv yesterday, and CNET managed to get a peek at its interface before it was taken down. The UI is reminiscent of Steam Chat but with more options, such as the ability to invite friends to watch videos together. It also includes built-in voice chat for Chrome browsers. A Valve representative told CNET that Steam.tv went live by accident and was meant to be an internal test as of today: "We are working on updating Steam Broadcasting for the Main Event of The International, Dota 2's annual tournament. What people saw was a test feed that was inadvertently made public," said the company.
