When they created stereoscopic 2D technology, they marketed it as "3D", even though it was nothing of the sort.
So now, when they're creating actual 3D technology, they have a marketing problem, they can't call it 3D movies even though that's what it is, because then people will associate it with the earlier, inferior technology. So now they want to call it VR??
It's not VR. It's a movie format with a fixed viewpoint. Sure you can look in all directions from that viewpoint, but you can't move around in this "world", because there's no actual virtual world to interact with. It's just a movie, not VR, don't call it VR.
