3D failed because the early tech was terrible and caused headaches and eye strains for most viewers. This put a "bad taste in their mouth" and they are reluctant to give 3D movies/TV a try again. In fact, I'm one of those people. I refuse (completely and utterly refuse) to go see a movie in 3D. I don't care if the technology has improved since my first experiences as a child. That's the problem with 3D. Which is why getting the VR tech right is so very important. It will flop if the eye strain, headaches, nausea, and other issues aren't fixed for "most people" - if those are even fixable things. This is why although the tech "exists" and there are "developer versions" out - for years now - they haven't been released. The above issues have to be sorted out first because the forefront runners and pioneers for current VR tech learned from the failure of 3D movies/TV. Although I'm much more interested in AR than VR. :)
