It doesn't need to be defined that strictly. The OP talks about FM radio adverts. An announcer telling you that a new song like, exists, could be construed in some sense to be an advert, just as my profile telling you that I am indeed a software developer could be.

But that's not really what's pissing people off and abusing their attention here.
