Early Color Television
RCA Compatible Color (NTSC System)
In late 1953, the FCC adopted the RCA compatible system. The first color television sets for this system were sold in 1954. They used a 15 inch screen. Later that year, 19 inch sets were made, and by 1955 all sets were made with a 21 inch picture tube. Several manufacturers made 15 and 19 inch sets, most in very small quantities.
