The TV industry is always looking for the next thing to make people upgrade. Remember 3D TV? Very much the metaverse of its era; a solution in search of a problem. Quietly largely forgotten about afterwards.
I'm not sure it was really a solution in search of a problem but it was a bit gimicky and there was very little content created to really take advantage of it. (Still have one--along with about five Blu-Ray titles that use it :-))
I will fondly remember how my dad bought a 3D TV (I was still a kid then). Our whole family watched Avatar in those cool glasses.
My family got a 3D TV too, we watched Avatar, and then never used it again. I wonder how many people share this exact scenario.
