I'm sure most people say "Advertising doesn't work, I've never bought anything because of advertising." Perhaps, though this ignores the fact that advertising is designed to inform, entertain, draw attention to a product, and drive interest or motivate purchase. It also helps maintain brand loyalty. There are many things advertising cannot do, as well, and one is assure business will be driven to the cash registers, particularly if the advertising is ill-considered.
But this is a good example of how advertising can not only entertain, but co-opt a message which is designed to hurt a business. It may not drive business, but God bless the owner who realized how to turn a bad situation to his favor.
Many people believe corporations and businesses are strong, particularly if they are large and have huge profits (as many car dealers often do). It is my view advertising is proof businesses are weak and competition is intense. Finding new and useful ways to get your message to break through the clutter is good for business. Done poorly, it can annoy, distract, and possibly hurt business. Done well, it can keep your consumer base intact or grow the foundation of purchasers. Or keep your opponents off balance.
