Product placement in TV shows is becoming increasingly common, yet little i
s known about its effectiveness nor even how to define and measure such eff
ectiveness. This research examined the effectiveness of product placement w
ith the use of two different types of measures: explicit measures that tap
memory directly (with the use of a recognition and recall task), and an imp
licit measure that measures the effect of exposure on product choice indire
ctly. It was hypothesized that the ability of product placement to enhance
memory and choice may be mediated by distinct mechanisms. The results showe
d an overall enhancement in product recall, recognition, and choice due to
placement. Further, although products central to the plot were remembered a
nd recalled more than products placed more subtly, no reliable effect of ce
ntrality of placement was observed on the choice measure. This dissociation
also occurred with modality of placement-where seen-only products most inf
luenced choice but were least recalled. The present data conform to theorie
s of memory, which predict that performance on explicit memory task can be
dissociated or uncorrelated with performance on implicit performance or cho
ice. This finding has significant implications for how product placements a
re designed and how their efficacy evaluated. (C) 2000 John Wiley & Sons, I
