I buy plenty of things that aren't advertised to me. From the services of folks to do things I don't want to do, to the constructions of things that I don't know how to build, to simple things like medicines that keep me from being dead.
I also buy some times that are advertised to me, but they are _far_ smaller in value than the things from the previous group.
Not everything that falls under manufactured impulse of society is advertising, right, although one can suspect that advertisements often goes far beyond what is clearly branded as advertisements.
When you see a Mac in a movie, it's already blurring the lines though most people might agree that it is product placement and actually there's sometimes warning about this before the movie start so I guess there are some laws about it at least in some countries.
When a super cool badass character smokes in a way that is clearly visually esthetically refined, even if no mark is either mentioned, this is still invitation to buy cigarettes. And this is not a fictional case here, it's well known that the guy who wrote the book "propaganda" later worked for the smoke industry. It's also well known that cigarettes have bad effects on people health.
