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.
It’ll be interesting to see if Valve keeps this sort of project limited to their own Dota 2 tournaments or eventually opens it up to people as an alternative to Twitch. With Streaming becoming such a huge business, it wouldn’t really surprise me to see them go with the latter but — as YouTube is finding out — it’s easier said than done.
