Advertising incorrectly can actually stimulates the sales of the advertisers competition.
E.g. Your driving your car and hear a pizza commercial on the radio.
You might think of the advertiser, but if you know this commercial your more likely to ask yourself if your hungry, then if you feel like pizza, and if so, then you'll probably order pizza from your favorite pizza place, which might not be the one that is advertised.
In the end you might even end up buying a burger instead. In this case the commercial just reminded you that you were hungary.
