Also see, the purpose of modern advertising. It's for the 2nd and 3rd order effects. Most modern mass advertising is not to convince you (directly) to buy the product, rather it's to convince you that *other* people are buying the product. If you see a message in a number of public places, you *know* that other people have seen that message, which in turn affects your behaviour (you know this brand is a "safe" choice and won't be seen as weird, for example). Real modern propaganda works not even 2nd or 3rd order effects, but 4th order, with a bit of reverse psychology.
