Advertising is common sense.
It doesn't take a genius to do it and, while experience is certainly useful, it doesn't take decades to become effective. Advertising takes many forms. There are, of course, those ever present TV ads with their frogs, lizards, clowns and 30 second mini-dramas. There are also billboards, blimps, neon signs and a long list of other efforts designed to write jingles, slogans and logos on our mental walls. Even though the amount of money spent for advertising has nothing to do with the quality of the product, we still prefer Budweiser, Tide, Goodyear and IBM to competing products that are not advertised.
