Advertising does NOT affect me 99.99% of the time. How do i know this? Almost all the groceries I buy has no advertisement or even branding. The vast majority of my spending goes to housing, Taxes, grocery bill, gas, maintenance and insurance. Almost none of the groceries I buy have any kind of logo, marketing or advertisement: cucumber, tomatoes, potatoes. Even when I buy soymilk, once I get through filtering all my conditions (organic, no added sugar, no added calcium/sodium, etc) I'm lucky if I even have 1 choice left. Beans come from nameless bulk, etc. Gas is based on location and price (not brand). Maintenance is always done at the cheapest place of the 3 closest repair shops. All my utilities offer me no choice at all. I have no idea what brand the clothing I'm wearing. etc.
I find this quite easy and intuitive. I'm not against advertisement at all. I've seen and remembered several advertisements but they almost never offer a product compelling enough to buy. When an ad does offer me something I actually want, I'll buy it (this happens for far less than 1% of my spending).
and yes, i'm well aware of how advertisements influence our perception of brands. but how is it effective if I never buy anything that has a brand? and when I do buy, I usually never have a choice: Utilities, etc
I have a 15" macbook pro that may have been aggressively marketed by Apple. But once again, I had no choice. the reason I bought it is because I'm a developer who used to create IOS apps and I needed the development environment to build apps (no choice but to use apple machines for that).
