Covered in the WIN Corporation thread
In short, WIN7 Griffith is taking Seven Sydney as a dirty feed complete with Sydney commercials. They did take the Wagga Wagga feed for about half a week at Seven’s request but then it changed to Sydney. There was some backlash from local advertisers about advertising from similar businesses in not-too-far-away locations suddenly getting a monopoly on airtime in Griffith but it wasn’t really clear who chose to switch back to Sydney feed, WIN or Seven.
The WIN7 stations in South Australia are taking Adelaide feeds.
