As early as 1929, two Melbourne commercial radio stations, 3UZ and 3DB were conducting experimental mechanical television broadcasts - these were conducted in the early hours of the morning, after the stations had officially closed down. In 1934 Dr Val McDowall at amateur station 4CM Brisbane conducted experiments in electronic television.
Television broadcasting in Australia began officially on 16 September 1956, with the opening of TCN-9, quickly followed by national and commercial stations in Sydney and Melbourne, all these being in 625-line black and white. The commencement date was designed so as to provide coverage of the Olympic Games in Melbourne. It has now grown to be a nationwide system that includes a broad range of public, commercial, community, subscription, narrowcast, and amateur stations.
Colour television in the PAL 625-line format went to a full-time basis on 1 March 1975 while subscription television, on the Galaxy platform, began in January 1995. Digital terrestrial television was introduced on 1 January 2001 in Australia's five largest capital cities.
Australia has three national public broadcasters, the Australian Broadcasting Corporation, the Special Broadcasting Service, as well as more recently, National Indigenous Television..
ABC Television is a division of the Australian Broadcasting Corporation, established in 1956. ABC, ABC2, ABC3 and ABC News 24 are available nationally, in addition to Australia Plus, focused at the Asia-Pacific region.
