The effectiveness of advertising depends on the amount and kind of product information available to consumers... advertising will be more successful the more impoverished the consumer's information environment.

Advertising generally works to reinforce consumer trends rather than to initiate them.

If there are signs that Americans bow to the gods of advertising, there are equally indications that people find the gods ridiculous. It is part of the popular culture that advertisements are silly.

Sales may lead to advertising as much as advertising leads to sales.

Most criticism of advertising is written in ignorance of what actually happens inside these agencies.

Even if, as is generally the case, everything that the ad says about the product is scrupulously honest, or at any rate scrupulously avoids outright dishonesty, the implication of the direct address of most commercials - that the announcer speaks with the viewer's welfare at heart - is fraudulent.
