Advertising is "pay someone to say/show something about your product", where "pay" can refer to any kind of payment. It's really really easy to separate, conceptually, from any other discourse.
Now, there are situations where this is more ambiguous, and in general any display of a company's products or brands, especially one that is not critical, is suspect of being advertisement for that brand.
I'm not even sure how you can even claim that there is any sort of ambiguity between, say, The Raven and a Super Bowl commercial.
Advertising is a judgement. It is a synthetic definition (defined but it's relationship to other concepts), but you want it to be analytic (ex: the number 5).
You completely dodge my point because it's a stake in the vampire heart of your non sequiturs.
