The contemporary sport fan has the ability to consume spectator sport through several means including event attendance, television and radio broadcasts, print publications, and Internet applications. Recently, an ancillary sport service, termed fantasy sports, has become one of the most popular activities among sport fans. As a result, the business of fantasy sports is booming. This study examined motivational dimensions underlying fantasy football participation from a Uses and Gratifications perspective. Utilizing Churchill’s (1979) five-step method for developing quality marketing measures, this study identified and validated three motivational dimensions: entertainment/escape, competition, and social interaction. The results suggest a pattern of fantasy football participation that is more purposeful and active than traditional media use. Discussed are the gambling associations, future research opportunities, and suggestions for developing fantasy football participation into a more creative and interactive marketing communication tool.
