One of the most iconic images of 3D TV technology is a black and white photograph taken in a movie theater decades ago. The audience--serious and riveted--is shown staring at a screen beyond the photographer and wearing the boxy black frames of 3D glasses (See image below).

For the second year in a row, 3D TVs made up one of the most robust product categories at the International Consumer Electronics Show, the world's largest consumer tech expo. The high-tech TV sets on display at booths belonging to big brands like Sony, Samsung, and Panasonic attracted gaping crowds.
