The Effects of Current Market Forces on the Impact of a TV Commercial in Creating Persuasion

The present study investigates the extent to which extenuating factors (excluding those produced by the commercial) affect the extent to which an advertisement is both persuasive and eventually engenders persuasion. The authors collected data from over 5,000 television commercials in the United States, and identified the existing market structure (e.g., brand share, number of competing brands, brand loyalty) surrounding each item at the time the product was advertised, in an effort to separate the effects of the advertisement from the effects of pre-existing market forces on persuasiveness. The results demonstrate that the combined pre-existing market forces have a greater impact on a commercial's ability to persuade than does the message or creativity in the advertisement itself. However, when pre-existing market forces between two products were similar, a creative advertising campaign was still identified as important in producing persuasion. Marketing strategy implications are discussed.
