> Nobody is immune to advertising - the people who fool themselves into thinking they're immune are less likely to notice its effects.
I'm not talking about people who think they are immune to advertising, I'm talking about people who take active measures to reduce its effect on them—be it technological (adblock), sensory (muting) or psychological (disdain). I would argue that people who think they are immune to advertising are not motivated to do any of these things.
In any case though, I have never seen any data or research that supports that common truism that "nobody is immune to advertising". If anything, it may be true that nobody is immune to some kind of advertising—not to generic advertising per se.
It is well accepted that advertising should be targeted by age, income, culture, educational level demographics. An ad designed for American teenagers probably won't work well on a middle-aged Indian lawyer, and an ad targeted at Indian educated professionals is not well suited for a 20-something Italian mechanic. So how can we assume that an ad that works on a person who makes no conscious effort to block or avoid ads will work just as well on a person who is constantly taking active steps to avoid them?
