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

If advertising is not an official or state art, it is nonetheless clearly art.

Chances are that neither the client nor the agency will ever know very much about what role the ad has played in sales or profits of the client, either short-term or long-term.

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.

Objectivity, in this sense, means that a person's statements about the world can be trusted if they are submitted to established rules deemed legitimate by a professional community. Facts here are not aspects of the world, but consensually validated statements about it.

It is very likely that many firms spend more on advertising than, for their own best interests, they should.
