This argument for the theoretical benefit of advertising (being informed about products/services) was probably true at the point in time when advertising genuinely consisted of a dispassionate listing of the features of a product, and maybe a picture of it. Take the commercial being highlighted here for example. It's 2.5 minutes of a very cool visual image of the toy balls bouncing en masse. But how does a zillion balls bouncing down a hill convey anything meaningful about the television model it's an ad for? How do sexy models in a commercial for beer, perfume, etc inform the consumer about the product in any actual sense?
