If my rememberance of assorted newspaper articles is to be trusted, there's a number of surveys in which the majority of respondents indicate they don't think they're influenced by advertising. In contrast, I must say I am fully aware that I am influenced by advertising, and a good's or behaviour's image more generally, but only in the negative. That is, it is clear to me that there's stuff I don't like solely because it has a negative image. For example, Apple's computers may exhibit excellent performance, but I would never buy one, because Apple has made it abundandly clear that Macs are products for people who think they can make themselves creative and individualistic by buying what millions of others also own.
