7HD

7HD is an Australian television channel, owned by Seven West Media, originally launched on 15 October 2007 featuring unique breakaway programming from 10 December 2007 to 4 October 2009 and a HD simulcast of Seven until 25 September 2010. The channel is available to high definition digital television viewers in metropolitan areas through a number of owned-and-operated stations. On 25 September 2010, 7HD was replaced by the new channel 7mate.

7HD returned as a high definition simulcast on channel 70 on 10 May 2016. Initially, the Melbourne and Adelaide markets received 7HD as a HD simulcast of Seven's primary channel while the Sydney, Brisbane and Perth markets received 7HD as a HD simulcast of 7mate; this was to allow Australian Football League (AFL) matches to be broadcast in HD in those markets. Sydney, Brisbane and Perth temporarily received 7HD as a simulcast of the primary channel for the duration of the 2016 Summer Olympics, before the change was made permanent during and after the 2017 Australian Open tennis.
