Editing ATN (section)

==History==
ATN-7 began broadcasting on 2 December 1956 and became the third television station in [[Sydney]] to begin regular transmissions.

The station opened in 1956 with principal offices and studios located at Mobbs Lane, [[Epping, New South Wales|Epping]]. The initial black and white cameras and other equipment was supplied by the [[Marconi Company]] of England. Conversion to [[PAL]] colour occurred on 1 March 1975. Digital [[DVB-T]] commenced on 1 January 2001.

The initial transmission tower in 1956 was located near the [[Australian Broadcasting Corporation|ABC]] tower at [[Gore Hill]], Sydney. This was eventually demolished after ATN was invited to share a new site at Artarmon which was built by a new 3rd, commercial broadcaster [[TEN (TV station)|TEN-10]].

ATN-7 commenced digital television transmissions on 1 January 2001, broadcasting on VHF Channel 6 while maintaining analogue transmission on VHF Channel 7.

ATN-7's Sydney transmissions are broadcast from masts operated by Transmitters Australia (TXA) at [[Artarmon]] and/or [[Willoughby, New South Wales|Willoughby]]. Retransmission translators to [[Ultra high frequency|UHF]] channels service Sydney viewers from [[Kings Cross, New South Wales|Kings Cross]] and [[North Head, New South Wales|North Head]] at [[Manly, New South Wales|Manly]] and north of Sydney at [[Bouddi, New South Wales|Bouddi]], [[Gosford]] and [[Forresters Beach]].

Beginning in the early 2000s, on-air programs were sent by digital link from the Seven Network's national program play-out centre at Docklands in [[Melbourne]] where the Master Control Room was located for all metropolitan and regional feeds to be controlled. Programming line-up, advertisement output, feed switching, time zone monitoring and national transmission output was previously delivered here. 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. In 2019 however, this function was transferred to a new play-out centre in Sydney as part of a joint venture with the Nine Network.

The analogue signal for ATN-7 was turned off at 9:00&nbsp;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 '''Good Night''' curtain at the end of the animation was tweaked to '''Goodbye''' and the TV mascot appeared for the final time to turn the analogue picture into a small white dot which slowly went away before going completely black, before the analogue signal itself was completely switched off.<ref>{{cite web |title=ATN7's vintage farewell to analogue |url=https://televisionau.com/2013/12/atn7s-vintage-farewell-to-analogue.html |website=Television AU |date=3 December 2013}}</ref>

In June 2023, 7NEWS moved their operations from [[Martin Place]] to their new purpose built studios in [[Eveleigh]]. In July 2023, Sunrise hosted its very first broadcast at its new studios. 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 (TV program)|The Morning Show]]’s [[Larry Emdur]] and [[Kylie Gillies]].<ref>{{Cite web |last=Knox |first=David |date=24 July 2023 |title=Sunrise, The Morning Show embark on new chapters in South Eveleigh studios &#124; TV Tonight |url=https://tvtonight.com.au/2023/07/sunrise-the-morning-show-embark-on-new-chapters-in-south-eveleigh-studios.html |access-date=7 August 2023 |website=[[TV Tonight]]}}</ref> Joining 7NEWS, 7NEWS Spotlight, The Latest and 7NEWS.com.au, for the first time in more than 40 years, the entire Seven Sydney operation and all broadcast and operational staff (across all departments) are now under one roof.
