ATN is the Sydney flagship television station of the Seven Network in Australia. The licence, issued to a company named Amalgamated Television Services, a subsidiary of John Fairfax & Sons, was one of the first four licences (two in Sydney, two in Melbourne) to be issued for commercial television stations in Australia. The station formed an affiliation with GTV-9 Melbourne in 1957, in order to share content. In 1963, Frank Packer ended up owning both GTV-9 and TCN-9, so as a result the stations switched their previous affiliations. ATN-7 and HSV-7 joined to create the Australian Television Network, which later became the Seven Network. ATN-7 is the home of the national level Seven News bulletins.
