The link between conspiracies and ads is way stronger than that. The ad industry really went into high gear following WWII when the people working on pumping out propaganda to drive their own side of the war stepped up the game by applying psychology, new media, and a bigger budget.

Those people and techniques then moved to the commercial market when the war ended and applied their trade to peddle us the crap their customers wanted to sell. Make us feel bad if we don’t buy product X and go on an endless consumption treadmill to try to feel good and adequate about ourselves.

It is despicable and even worse with ads targeting children.
