Companies are starting to re-think their advertising strategies. There are studies that prove that, in some cases, when a commercial has been relatively sucessful, people will remember it for a long time, even years, but most of them will not remember which product was it advertising, or sometimes they will even think it was the competitor. Therefore, some of those "funny" commercials have a negative impact in the long term.
I don't mind being portrayed as a moron because, I have to admit, men in general are very single-minded: sex, food, drink, speed. Those are the things that drive us. Advertisers know that, if you want a man to get up of the couch and go buy their products, it has to give him one of those four things, directly or indirectly.
