SES-8 Mount Gambier
SES-8 Mount Gambier began transmission on 25 March 1966. The callsign stood for South East South Australia. Translators would be later setup at The Gap on UHF-32, Border Town on UHF-49, Keith on UHF-33, and later at Kingston/Road on UHF-59. The station was owned by South East Telecasters.
In 1982, SES-8 adopted a logo similar of that of sister stations BTV-6 Ballarat and GMV-6 Shepparton, becoming part of the SIX Network Victoria until 4 December 1989 when GMV-6 and BTV-6 were both rebranded to VIC TV.
WIN South Australia
On 15 August 1999, WIN Television acquired SES and RTS and integrated them into the WIN Television network, with the branding now matching that of the Nine Network.
SES becomes a sole Nine Network affiliate after MGS-41 begins transmission on 1 January 2004 as an affiliate to Network Ten.
On 7 August 2009, WIN recommenced broadcasting Channel Nine as a digital-only service (SES Digital (SDS) in Spencer Gulf and RTS Digital (RDS) in the Riverland) starting on 4 October 2009. The channel is a direct feed of NWS-9 with the exception of local commercials.
Seven South East SA
After SES/RTS' analogue signal was switched off on 15 December 2010, the channels WIN SA, WIN Nine and WIN Ten were renamed Seven SA, WIN SA and Ten SA. MGS/LRS now only shows Network Ten programming after aligning with them on 1 July 2016.
