Are you regularly exposed to ads? I don’t understand this at all. Advertisement has next to nothing to do with “telling you about a product” which is why old ads are funny today. They hadn’t figured out a lot of the techniques we use to elevate advertising so far beyond that. An easy example, which some old ads even caught onto, would be associating the product with something else the consumer desires. Ever see an ad for a car with a happy family in it? Ever see an ad for a sportier car with a guy driving around an attractive lady? Is the happy family related to the function of the car? Of course not; the goal is to tie the thing the consumer wants (a happy family) to the thing they don’t yet (the car).
