Could Valve be cooking up a new service called Steam TV? A mysterious new url seems to indicate as such, and after some digging a few clues does seem to tie the service back to Valve.
Pavel Djundik, the creator of SteamDB, tweeted out the Steam.TV url earlier today confirming "yes, it's real," though he might have only been referring to the url and not the service. When the url was first discovered it initially read "Welcome to steam.tv" though it has since been taken down.
PCGamesN discovered through Who.is that Steam.tv's SSL certificate leads back to the Steam Community; a little odd considering Valve's Steam Store is usually the site Steam related webpages link back to. Other details about the page are protected, but the domain is registered through Namecheap, the same service Valve used to register the website for its upcoming card game Artifact.
Based on the name and how the page links back to the Steam community there's a good chance that Steam TV could be the name of a Twitch-like streaming service. But to be perfectly clear the name could refer to any number of services.
Valve is currently keeping very busy as of late. The company recently purchased Firewatch developers Campo Santo along with Firewatch art director Olly Moss; the company is also preparing the launch of its Dota 2 card game Artifact which will be playable for the first time at PAX West. Steam TV could be any number of projects at the company so we'll have to wait for more details.
