My view is that what doomed 3DTV was less the glasses required for 3D viewing -- which are a significant issue -- but more the fact that 3DTV simply wasn't that compelling a viewing experience.
What is most interesting about the experiment with 3DTV is how it completely tracked the initial enthusiasm for 3D movies in the 1950s and then their subsequent fall from favor. Around 1980 or so I saw the 3D Creature from the Black Lagoon and Dial M for Murder, but they didn't make me wish that the big films of that period, like Jaws or Star Wars, were in 3D.
