If you have 1M people around the world checking into a VR camera atop a car going around the Indianapolis Motor Speedway at 200MPH you need bandwidth and image quality. I want to see what the driver see's in near perfect image quality and be able to look around when he goes wheel to wheel around a turn. The entire layer of crap that's fed from whatever service, NBC, ABC, ESPN, etc will flatten and the consumer will be able to watch the event as if they were in the action themselves. 5G will help in driving that engagement.

EDIT: Given how crazy America is about football, my guess as well is the NFL could sell millions of VR related tickets to the Superbowl in a similar scheme. The hitch in my opinion is commercial breaks will ruin the experience if commercials as they're broadcasted today happen in VR - people will want to plug themselves into the action with no obstructions.
