3D theaters continue to increase in number
And while “3D TV” is mostly gone at present, 3D video projectors are very common. Most video projectors support 3D because it is very inexpensive to add 3D to a projection system while it was expensive to put the tech into flat panel TVs.
If you are looking for 3D viewing options at home, 3D projectors are a good option. Another option is 3D computer monitors, which are used in gaming and engineering and other visualization applications.
