advertising) and 341 community (publicly funded) radio stations. National news radio broadcasters include the Australian Broadcasting Corporation which operates 4 national radio news networks (including ABC News Radio and ABC Radio National), 53 local news stations through ABC Local Radio and several digital radio stations; and the Special Broadcasting Service which also delivers multilingual Australian-produced news content. Regulation Regulation of the media is principally assured by the Australian Government through its power to make laws governing telecommunications. The Australian states and territories also have important roles in this area, notably in the area of defamation law, although their laws may not conflict with a valid federal law. The Australian Communications and Media Authority (ACMA) is the broadcasting regulator for radio and television in Australia, and also the co-regulatory Online Content Scheme. Consumers who have complaints about programs on television and radio or certain types of content on the Internet can apply to the ACMA. The Commercial Television Code of Practice is a set of regulatory guidelines, registered with the ACMA, with which commercial television broadcasters should comply. The Australian Press Council is the self-regulatory body of the print media. The Council deals with complaints from the public about editorial material in newspapers and magazines published in Australia, and aims to maintain the freedom of the press. Media ownership Controls over media ownership in Australia are laid down in the Broadcasting Services Act 1992, administered by the ACMA. Even with laws in place Australia has a high concentration of media ownership compared to other western countries. Ownership of national and the newspapers of each capital city are dominated by two corporations, Rupert Murdoch's News Corp, (which was founded in Adelaide but is now based from the United States) and Nine Entertainment – Murdoch-owned titles account for nearly two-thirds (64.2 per cent) of metropolitan circulation and Nine-owned papers account for a further quarter (26.4 per cent). The Australian Associated Press (AAP) is owned by a not-for-profit organisation. The AAP distributes the news and then sells it on to other outlets such as the Australian Broadcasting Corporation. Although much of the everyday mainstream news is drawn from the AAP, all the privately owned media outlets still compete with each other for exclusive pop culture news. Rural and regional media is dominated by Australian Community Media, with significant holdings in all states and territories. Rural Press received a takeover offer from John Fairfax Holdings
