Flat panel televisions have been very popular for the past several years. Flat panel televisions replaced televisions with picture tubes called cathode ray tubes.
Some early flat screen TVs used cathode ray tubes, but the flat faced tubes were harder to make and heaver than the older curved faced tubes.

A cathode ray tube is what was used in televisions and computer monitors before the advent of the LCD, LED, and Plasma tv screens. They are big, bulky, and very heavy. They are a vacuum tube, with an approximately flat face, on the inner surface of which is deposited a phosphor. When electrons from the cathode asembly reach the phosphor, they cause it to glow at that spot.
