Advertising clearly works, why spend £££££ otherwise,whether it works specifically on the person who sees it I dont know.
Im sure that it works on me, I’d be a fool to try and suggest that I havent bought things on the basis of seeing an advert for, say, a chocolate bar and thinking “I’d like that”.
There was at least one individual on here (TJ!) who swore blind that every product he bought was purchased solely on his terms and that advertising played absolutely no part in his decision process.
I didnt believe it then and I dont believe it now.
Advertising isnt just about creating a need and a desire for a product, its about making us aware of it.
It also depends how you define advertising. I could be someone riding a nice looking bike, it could be a review in a magazine, it could be anything.
