Samsung reportedly has not placed orders for 3D glasses for 2016 (but that is from one vendor – perhaps they switched vendors). LG itself says that 3D support will only be in their premium, high end TVs, cutting “the number of supporting TVs by half”.
Update: Feb 23, 2016: Philips says “3D is dead”.
Meanwhile, viewing of 3D movies in cinemas continues to be strong.
I recently watched some of my own 3D videos on my LG 3D TV and was reminded of how much I enjoy watching the richer imagery of good 3D.
