@Richard_Littler I think it's more about humans being desperate to be fashionable, following trends, fear of missing out and keeping up with the Joneses - this is what sells products to people. I think advertising is more about ensuring people have heard about the product, I'm not convinced it makes people buy. I've always tried to maintain awareness to control the effect on myself, taking a step back and asking, why am I buying this, do I really need it? Anyway, just my point of view.
