Advertisements work opposite for me. If I see an ad, I hate the company. I adamantly will only choose materials based on personal research and the suggestions of my peers. Any suggestion by a corporate entity or otherwise paid method will only serve to brew hate. Beyond that, I will go to just about any means to get rid of ads. I often refuse to deal with a company if their ads show up when I don't want them to, or if their ad annoys me. There is no good ad.
