All Seven Network owned and operated studios used to have their live signals relayed here: for instance, ATN's output was fed to HSV and then transmitted via satellite or fibre optics to the towers around metropolitan Sydney.

The analogue signal for ATN-7 was turned off at 9:00 a.m. on 3 December 2013 by using a special five-minute retrospective clip of the local station and the song "My City of Sydney" by Tommy Leonetti, used for the first time in 30 years, combined with the old "Mother kangaroo putting her baby joey to bed" animation, which was played during the channel closedown sequence until the network began 24-hour service in 1993.

The first edition went to air live at 5:30am on 24 July 2023, with hosts Natalie Barr and Matt Shirvington, newsreader Edwina Bartholomew and sports presenter Mark Beretta, followed by The Morning Show’s Larry Emdur and Kylie Gillies.

The new space cover two floors of Seven’s head office and are five times larger than the previous Martin Place location, with permanent sets for all programs.

Visiting commentators from the United States organised for ATN staff to supply the camera and transmission systems for CBS' coverage of NASCAR races.

Later in the mid-1980s, the American Broadcasting Company asked ATN staff to develop aerofoil-designed cameras suitable for Formula One cars, and these were subsequently used at the Indianapolis 500.

On 25 June 2023, Seven News Sydney signed off its final bulletin at Martin Place studios, wrapping 19 years and 6,873 days of broadcast.

The new space is five-times larger than Martin Place, allows for permanent sets for all programs, with two complete control rooms and more than 40sq m of LED screens, while all newsroom operations will now be located on a second entire floor.
