RT Journal Article SR Electronic T1 Measuring the Long-Term Effects Of Television Advertising JF Journal of Advertising Research JO J Advert Res FD WARC SP 123 OP 131 DO 10.2501/JAR-55-2-123-131 VO 55 IS 2 A1 Leslie A. Wood A1 David F. Poltrack YR 2015 UL http://www.journalofadvertisingresearch.com/content/55/2/123.abstract AB Advertising influences brand purchase through short-term effects determined by direct increases in penetration, basket size, and buy rate. Advertising also influences brand purchase through long-term effects determined by indirect increases of future purchases through trial and increases in loyalty and brand equity. The current study measured the long-term effect of television advertising by tracking households' purchases that were exposed to advertising out for a year after the initial short-term period. By measuring the increases in these “future purchases,” this method captured the influence of advertising on long-term brand purchases. It also reported the multiplier required to translate the short-term measured effect into the total long-term and short-term effects of advertising.
