RT Journal Article SR Electronic T1 A Look at the Long-run Effectiveness of Multimedia Advertising and Its Implications for Budget Allocation Decisions JF Journal of Advertising Research JO J Advert Res FD WARC SP 241 OP 254 DO 10.1017/S0021849905050269 VO 45 IS 2 A1 Vakratsas, Demetrios A1 Ma, Zhenfeng YR 2005 UL http://www.journalofadvertisingresearch.com/content/45/2/241.abstract AB This study examines the long-term effectiveness of multimedia advertising in a competitive setting and its implications for budget allocation decisions, using multivariate persistence methodology. Analysis of network TV, spot TV, and magazine advertising for the two major competitors in the U.S. SUV industry suggested that long-run advertising effectiveness differed considerably among media. These differences were attributed to the media lifespan, retrieval, and content of the message they convey. The authors propose that budget allocation decisions should consider the long-run effectiveness of the different media employed to increase the productivity of advertising campaigns. They also conduct a simulation experiment to further investigate long-run sales effects of alternative allocation strategy scenarios.
