On Sliver.tv, you can watch other people play games such as Counter Strike: Global Offensive, League of Legends, and DOTA 2, all in VR. Sliver.tv (not Silver.tv) gives you a VR view of games, even if some of the games themselves are not in VR.
Sliver is free, and is currently available for Android and iOS, in Google Cardboard format and 360 window format. It will soon be available for HTC Vive, Oculus Rift, Samsung Gear VR and Playstation VR.
Here is the official website.
