The simulcast is a one-time-only affair, although there will be opportunities to watch afterwards. Uber is even providing the VR experience on-demand in San Diego through July 24th. You won't have to be picky about how you watch, at any rate. It'll work through the Within apps on Android (including Gear VR), iOS, the HTC Vive and the Oculus Rift. The simulcast is undoubtedly something of a gimmick. At the same time, it'll also represent a rare, nationally-shared VR experiment -- there will be thousands upon thousands of viewers to talk to when it's all said and done.
