Advertising, marketing, propaganda. It programs people’s brains. It is extremely powerful.
There are dozens of these mass brain-programming campaigns going on right now. It’s been happening for many years … maybe centuries.
The effects can linger for many years. Even passing to the next generation.
I don’t love to defend advertising/marketing, but your statement implies that once something has been advertised, organic interest/enjoyment becomes impossible.
Sure, there might’ve been a big ad push that rocketed mayo to the top of people’s condiment lists. But there are dozens of other things that could also create interest (new foods that pair well with it, new recipes that are shared culturally, loss of a competing product, diet changes)
