#7 Colour television

Year: 1953

Although introduced in the U.S. in 1953, only a few years after black-and-white televisions had been standardized there, high prices and lack of broadcast material greatly slowed its acceptance in the marketplace. Although the first national colour cast, the 1954 Tournament of Roses Parade, occurred on January 1, 1954, it was not until the mid-1960s that colour sets started selling in large numbers, due in some part to the colour transition of 1965 in which over half of all network prime-time programming would be broadcast in colour that fall, and the introduction of GE's Porta-Colour set in the Spring of 1966 which would bring the first all-colour prime time season beginning that fall.

By the late 1960s and early 1970s though, colour sets had become standard, and the completion of total colour casting was achieved when the last of the daytime programs converted to colour and joined with prime time in the first all-colour season in 1972.
