Like I said, "you will never be able to completely avoid advertising without taking yourself out of mainstream society" and "second-order advertising is much harder to deal with".
I don't claim to be immune to advertising, or know how to avoid all of it! But knowing you are susceptible to advertising is the first step towards not letting it influence you (too much).
Also, it's quite possible to watch TV shows for free without advertisements.
And, how do you get around product placement?
