Watching the Olympics on TV? That's so 2012, apparently. The BBC is launching an "experimental" service on Friday that will broadcast the action in 360-degree video instead. It's not a complete replacement -- only 100 hours will be shown throughout the tournament. But it's more than a token gesture, with one live event and a highlights package planned for each day. They'll be accessible through a new BBC Sport 360 app for iOS, Android and Samsung's Gear VR headset. Coverage will also be available through BBC Taster, a website for the BBC's off-the-wall projects.
