One of the big advantages is the space saving. The problem with old cathode ray tubes is that they needed a lot of space so that the rays can fire upon all areas of the screen. The wider the screen, the larger the volume of the television would be. The average Plasma television is around 6 to 8 inches deep. Moving your Plasma onto the wall can really increase the amount of floor space and they can be looked at from almost any point in the room (usually 180 degrees)
