You mean, the companies who want me to give them money. I'm sure there are a few companies out there whose product I actually want and don't mind paying for, but their number is absolutely dwarfed by the number of companies that seek to induce FOMO/status anxiety/etc in order to get me to buy things I don't need and would not want if not for advertising.
How many problems do most people have that can be solved with an existing product they are unaware of? The numbers can't be very high.
How do you explain well-known brands advertising the same product for decades on end? Surely Coke and Pepsi aren't suddenly enlightening many people to the existence of their drinks.
How about ads that get shown to the known-same individual time and time again after mere minutes? (See Hulu, at least back in the day, not sure what it's like now.)
The whole line about ads being mere consumer education is ridiculous and doesn't even stand up to a cursory thought.
