I think it depends on the product, and if the commercial is any good. Many times, commercials can be really terrible and actually drive people away from a product. Case in point, the Vonage commercials with that techno music. Did they honestly think people would want to buy their product after seeing them? Annoying = no buy, most of the time. And I know they do that to make people remember their product, but honestly, whatever happened in making people feel good about your company and product? That's what I was taught about in marketing class. I think it's really difficult making a good commercial that will click with people. There are only a handful each year that end up being really clever. There's one bank commercial on these days that recently started playing that I really like, where the clerk begins to tell the client that he's the boss of his savings, and so he gets up on the desk and starts to say, "I'm the boss! You, take my calls, you stop lallygagging, you do a jig!" And it works because it's funny and it works on the concept of spontaneity and it creates that brand awareness.
