The type of ad that merely informs you of an existence of a product is possible in theory, and maybe existed in 19th century, but I was born too late for that.
I have purchased clothes, plush animals, books, and games because of online advertisements that told me about their existence; I would have been unaware of the products in question if not for the ads. (I have also generally been happy with the products that I got; one of the clothes that I ordered is probably my favorite piece of clothing.)
