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.

TCN is the flagship television station of the Nine Network in Australia. The station is currently located at 1 Denison Street, North Sydney. The licence, issued to a company named Television Corporation Ltd headed by Sir Frank Packer, was one of the first four licences to be issued for commercial television stations in Australia. TCN-9 is the home of the NRL coverage and national-level Nine News bulletins.
