The Australian Broadcasting Corporation (ABC) is Australia's national broadcaster founded in 1929. It is currently principally funded by direct grants from the Australian government, but is expressly independent of government and partisan politics. The ABC plays a leading role in journalistic independence and is fundamental in the history of broadcasting in Australia.
The first public radio station in Australia opened in Sydney on 23 November 1923 under the call sign 2SB with other stations in Melbourne, Brisbane, Adelaide, Perth and Hobart following. A licensing scheme, administered by the Postmaster-General's Department, was soon established allowing certain stations government funding, albeit with restrictions placed on their advertising content.
