It seems that over the weekend Valve has inadvertently enabled then you [Steam.tv] streaming service making it live for a brief spell on Friday evening with a broadcast window set up for ‘The International’, Valve’s big Dota 2 tournament.
The recently launched Steam Chat is also available via the new Valve streaming service providing those being entertained with an opportunity to discuss the streaming content. Unfortunately the website at Steam.tv is no longer available but you can expect it to be launched in the very near future. You don’t need to log into your Steam account to watch, but you will need an account to access your Steam Chat friends list and group chats etc.
No official date has been announced when Steam.tv will launch however judging by the content of the holding page we can assume that the service will be made available just before the launch of The International. Soon as more details are made available from sources or officially announced by Valve we will keep you up-to-date as always.
