It's not ironic. It's statistics. Advertising works on a percentage basis across a population. Over all, it sells more products. If it didn't, people would stop doing it. You may happen to fit within a percentage of the population that will not buy the product after seeing an ad, but that segment is far, far smaller than the percentage of the population that will go out and buy a product after seeing an ad.
