I'm reasonably certain that advertising works on most people, even if they don't realize it. Being told a modified and heavily-biased narrative of the world repeatedly, for literal hours a day is likely to have an effect, even if it's subtle.

Maybe you're one of the lucky people that advertising truly does not work on, and fair enough, but I seriously doubt that these big megacorporations would spend billions of dollars on ads if there weren't some measurable effect on a majority of people.
