Abstract
This study represents a supportive test of the attractiveness aspect of the “match-up” hypothesis of celebrity/product congruence discussed in depth by Kahle and Homer (1985). The hypothesis implies that the physical attractiveness of a celebrity endorser may only enhance both product- and ad-based evaluations if the product's characteristics “match-up” with the image conveyed by the celebrity. Empirically, it was found that for an attractiveness-related product, use of a physically attractive celebrity (Tom Selleck) was observed to significantly enhance measures of spokesperson credibility and attitude toward an ad, relative to use of a physically unattractive celebrity (Telly Savalas). Alternatively, the physically attractive celebrity was found to have no effect on various spokesperson-, product-and ad-based dependent measures relative to the physically unattractive celebrity for an attractiveness-unrelated product. Implications of these findings for advertising strategy are discussed, and directions for future research are outlined.
