Rob,
You make some excellent points. Most people who say they aren't affected by advertising are selecting only the most annoying sales pitch. Most of our brand loyalties come from advertising. Is Ford, Chevy or Dodge better than one or the other? I used to argue with my friends all the time about it until I realized that I didn't have a clue about what I was talking about. Still don't. The only thing that makes one better than the other is the "PERCEIVED" impression we have of that product.
Manufactures know that if you bought one of their products once, you are more than likely to buy from them again. To increase those odds, commercials are targeted at making you feel good about your purchase, which leads you to buy from them again and again. Food and beverage companies are the most obvious sources for this.
And remember those really annoying commercials? They do that on purpose because you remember them. It's a proven fact that a cerntain percentage of people will buy a product from somebody just because they have heard of them before. It's how some people vote on election day.
I think it was Bank of America that did a study on what it costs to get new customers. Something like $1,200 in advertising per new customer. Every bank knows these numbers, even though they vary by some amount. The point of that story was that it takes so much to get a customer, but nothing to lose one. It also shows a direct link to the effectivness of advertising.
I also perfer to make my purchases based on information I'm able to gain from outside sources and recomendations from people I trust. But sometimes you just don't know where they get their information from.
I was at Tri City one time in Fremont CA looking at some new ski boots. The guy next to me asked the sales rep what pair of boots were better from a group of similar priced boots. The sales rep told him the brand he liked the best and why he thought it was better than the others.
The guy had a briefcase and pulled out some papers. He told the salesman he was a rep for that brand and for reckomending their brand he was given a check. I don't know the amount, but just the fact that this happens, and I watched it myself first hand, makes me question all of it.
