As television broadcasters and their audiences begin the massive and expensive transition to digital High Definition TV, you might be interested in the last major television revolution: the big change to COLOR broadcasting in the 1950s-60s. Until 1953 television had been strictly black and white. There were competing schemes for transmitting color pictures, but in 1953 the RCA "compatible-color" system was accepted as the standard by the FCC. RCA's system allowed color images to be transmitted and received on either monochrome or color receivers. But the RCA/NTSC Color Television System will soon be phased out because the FCC requires broadcasters to complete the changeover to digital transmission by 2007.
