The following quote came from Seven National News reporter Alan Murrell on the 27 December 1987 edition regarding the move:
"Tonight will mark the end of the callsigns ADS-7 and SAS-10. Tomorrow, they be rebranded as ADS-10 and SAS-7. It’s the first time such a change has been made. The switch follows a media shake-up earlier this year, which left ADS in the hands of the owners of the Ten Network. Already, the cosmetic changes are being made at Strangways Terrace and Gilberton. But viewers will notice little difference. They’ll still turn the knob to Ten for Channel Ten programs, and to Seven for Seven programs.
"The only difference will be that the local personalities will be seen on different channels. So if you want to watch Steve Whitham and Caroline Ainslie reading the news tomorrow night, you simply turn the dial three positions, from Seven-to ADS-10. And it’s as easy as that."
This is a list of programs which made their premiere on an Australian television network that had previously premiered on another Australian television network. The networks involved in the switch of allegiances are predominantly both free-to-air networks or both subscription television networks. Programs that have their free-to-air/subscription television premiere, after previously premiering on the opposite platform (free-to air to subscription/subscription to free-to air) are not included. In some cases, programs may still air on the original television network. This occurs predominantly with programs shared between subscription television networks.
