On This Day - March 1st 1975

Colour television begins broadcasting in Australia. 

The history of colour television goes back to an early patent application in Russia in 1889 for a mechanically-scanned color system. John Logie Baird, instrumental in the development of television, demonstrated the world's first colour transmission on 3 July 1928. It was not until after WWII, however, that experimental colour television broadcasts were transmitted in various locations around the world; 1953 in the USA and 1967 in Europe.

In Australia, colour transmissions began to be tested on the commercial television networks on 19 October 1974. Colour television was officially implemented on 1 March 1975 and proved to be so popular that by 1978 two-thirds of Australian viewers had bought a colour set.
