Technology Has Changed the TV Stand

TV stands, audio racks, and entertainment centers have evolved with the changes in television technology. The days when televisions were considered a stand alone piece of furniture are long gone. Compared to the TV sets built just a few years ago, modern television sets are very different. The physical enclosure has changed, just as technological advances in television design have enhanced picture quality

Televisions became commercially available in the nineteen forties and the basic technology has revolved around the picture tube. The picture tube is a large cathode ray tube with a series of electron guns in rear of the tube. The electron guns shoot electrons at the front of the tube, which is coated with a fluorescent material. The fluorescent material causes the electrons to diffuse, the fluorescent material glows and through a series of signal modulations, a visible image can be seen.

An older CRT television that measures twenty six inches diagonally may be as deep as twenty four inches. Compare that to a new high definition television, which might only seven or eight inches deep.
