Paying a 3rd party to spread a message or information would be an interesting way to define it. In that scenario things like classifieds, craigslist, and job boards would all get the ax too. I like to think about these issues because I make a living selling advertising on my website. We try to have use good practices, have the ads be high quality, targeted toward the content as opposed to the user. On the other hand, I live in a city which does not allow billboard advertising (Santa Barbara, California) and I do enjoy it in comparison to cities with many billboards.
