Don't these programs come via Foxtel in AU?? I seem to remember seeing in the past the occasional start or finish of an Ozzy add during the commercial breaks when Sky is a bit slow..
Sky provides programming for Prime, Box, Vice, Box Sets, Living, Food, Sky Arts, SoHo Movies (except TCM and Rialto), Sky Sports 1-4 + popup and Main Event. All others channels are programmed by companies other than Sky TV, and thus Sky don't control the amount of advertising they show.
A lot of the other channels (like Discovery, Nat Geo, and the kids channels) have programming in both countries (where the Australian broadcast is delayed by two hours). Crime Investigation is unique in that between midnight and 6am, they show Foxtel advertising. I haven't noticed this on other channels.
From a consumer point of view it doesn't really matter who controls the advertising content
It's still advertising within a paid-subscription service. Ironically, it drove me away from the very channels it was trying to promote.
