Earlier today, a tweet from Pavel Djundik pointed us to the domain Steam.tv, but at that time it was a blank site which simply read "Welcome to Steam.tv." A glance at the certificate showed it to be a legitimate Valve website, which was curious, but not quite enough to report. While we've suspected that Valve has Twitch dreams in its eyes, all we could do was speculate.

Later this evening, though, Valve apparently launched Steam.tv with a livestream of The International 2018 and chat bar. Cnet says that it's just the Dota 2 stream for now, and that you can log into your Steam account and access your friends list for group chats. It also has voice chat support in Chrome.
