The Australian Broadcasting Corporation (ABC) is Australia's national public broadcaster, known previously as the Australian Broadcasting Commission. With a budget of AUD$823 million, the corporation provides television, radio and online services throughout metropolitan and regional Australia, as well as overseas through the Australia Network and Radio Australia. Through its commercial arm, ABC Commercial, the corporation runs a chain of retail outlets, selling books, audio and video recordings, and other merchandise related to its programs.

Founded in 1929 as the Australian Broadcasting Company, it was subsequently nationalised and made a state-owned corporation on July 1, 1932, becoming the Australian Broadcasting Commission. Following this, the Australian Broadcasting Corporation Act 1983 changed the name of the organisation to the Australian Broadcasting Corporation effective July 1, 1983. The corporation produces programmes and information services, broadcasting nationally on television, radio, and the Internet. The ABC is often referred to informally as "Aunty", the origin of this name derives directly from a nickname of the ABC's cousin, the BBC.
