Agree with much of what you're saying UNDEF, but I have nagging doubts. Coors commercials, for example, really irritate me to the point of reflecting negatively on the product. Sure, I have no doubt about who's product is being hawked, but I really think that subconciously, I'll be less inclined then before to order a Coors after being subjected to those spots. Admittedly, I'm not involved in marketing and I could be off base. While maybe before I didn't think about Coors when buying beer, now I'm thinking about NOT buying Coors.
On the other hand, there are annoying ads out there that I never recall what's being sold. There is a current one for (I think) cars that has guys flipping over railings and other 'Crouching Tiger-type' choreographed moves, but I have no idea what brand the ad's for. Not only is the ad stupidly annoying, I have zero recollection of what they are selling.
