I think I took an advertising class long time ago (so long ago that I don't remember if it was an actual advertising class, Advertising 101 or some marketing class). But, what stuck to me was, that most people said that they were unaffected by ads, and the data showed otherwise. Ads also help with brand recognition etc. Typically, people are very familiar with some space, say desktop CPUs... and they'll say, "I'll never buy an intel CPU just based on an ad", and that might be true. However, when it comes to a space that's completely far away from their day to day expertise, say... weedkiller in the garden, and they're more likely to trust a branded product that they've seen product placement or other types of ad. Of course, not everyone is that way, but ads have different objectives, and they are effective.
