The Steam Universe is Expanding in 2014. That tagline sure looks to be true with the announcement of SteamOS, a new stand-alone Linux-based operating system set to combine the best parts of the Steam client with the open source nature of Linux. The announcement page goes into significant detail regarding the benefits of SteamOS as a stand-alone platform, including a number of performance improvements related to graphical processing, and how the SteamOS will operate as a "collaborative many-to-many entertainment platform", potentially allowing community members and hardware developers to innovate and improve at a faster pace than on closed platforms. The SteamOS page discusses a number of brand new Steam features which will be shipping to both SteamOS and the main Steam client in the future, including the previously announced Family Sharing system and three brand new features in the form of "In-home Streaming", "Music, TV, Movies,", and "Family Options". In-home Streaming will allow a user to stream Mac and Windows games straight to a SteamOS computer elsewhere in the home over a local wireless network, something which has been a personal goal of Gabe Newell for some time now. The Music, TV, Movies section mentions that Valve are currently working with a variety of other media services and providers to introduce music and video content onto the Steam client and the SteamOS. The Family Options section discusses how Valve are working to expand the Family Sharing system by providing deeper customisation options to allow for more control over which game or software titles can be interacted with by other members of a family group. As always, we'll be sure to bring you even more information about the future of both SteamOS and the Steam client as we learn more in the coming weeks. Until then, be sure to head on over to the main SteamOS announcement page to read all about the upcoming operating system for yourself. The next countdown timer is set to conclude at 5pm GMT on Wednesday 25th September 2013, around 48 hours after the announcement of SteamOS, so be sure to come back shortly after the next announcement to learn more about the future of Steam in the living room.
