The point a lot of people miss is that advertising doesn't just convince you buy new things. Many advertisements are designed to make you feel good about the products you already buy so you won't consider trying the alternatives.
When you grab a bottle of dish soap off the shelf, do you select the same one each time because you prefer it for reasons you can't quite articulate or do you grab whatever's cheapest because they're basically all the same?
I was about to disagree until I read your example. You're right - I buy a lot of stuff for reasons that aren't grounded in reason, and, although I usually relate to stuff such as "my Mom used to have this one at home when I was a kid", well, who knows if that's the actual reason or just some justification from my mind.
Their purpose isn't to randomly convince someone to spend $20-30k on a brand new vehicle.
The purpose is to convince people who've already bought the car that they made the right decision and to feel good about it - and to rave about their new exciting, big purchase to their friends/family.
I buy the allergy friendly one of the store brand that I’ve never seen an advertisement for. Since it’s the store brand the type variates since I don’t always shop at the same store.
But you’re right, I probably buy Coca Cola (and like it better) instead of Pepsi because of life long branding. I’m not sure I’ve ever seen an online advertisement for Coca Cola though.
