First there was black-and-white TV. Then along came color TV. Then came HDTV. And now 3D HDTV. The movie Avatar (which I was thought it was Disney's Pocahantes and the move Titanic, except with better special effects) was the reason why this idea went from concept to reality so quickly.

How does it work? Well, you still have to wear those funny polarized glasses. So it works the same way as it does in the theater. The reason why new TV's are required is because the HDMI cable standard, which is the cable that send boths audio and video to the HDTV, had to be updated. You are going to also need to buy a new 3D Blu-Ray player. (However, the Playstation 3 may be able to support the new 3D movies. Emphasis on may right now.)

Information is hard to get about it right now. But expect to see 3D HDTV's on the shelf soon. And expect to pay double that of regular HDTV's.
