I half thought about getting a copter and a Hero 3 for some Youtube stuff. A few months back at a 5k my wife ran, there was a guy with that setup that was apparently hired to do the race on video.
I’ve been getting YouTube ads from these guys lately:

They have one drone setup with built in camera, and a headset for the operator that creates the visual illusion that you’re actually in the thing.
All sorts of different devices on there.
