By any definition, a podcast is part of "internet advertising" but there's less conflict there. Sure, I want to hear the hosts and not the ads, but if the ad is relevant, I don't mind the interruption, and hey sometimes it's an interesting product for me. There's a tension between the content and the ads, but not a fundamental contradiction.

No, this is the outcome of all interest targeting based models. You're interested in X, and they either don't show you X (to get X to pay) or they show you Y (which you aren't interested in) because Y paid.

Whereas with demographic targeting, hey I'm in demographic X and wasn't looking for a Y now, but sure, I'll remember it for when I'm in the market for one later.
