While sport has become a viable component of the marketing promotion mix, a comprehensive set of factors for evaluating the motivations of consumers who watch or play sport is still lacking. This research begins to fill this void by suggesting a motivations framework to organize constructs for evaluating sport consumption. The empirical study develops scales to measure motivations for spectating and participant markets and profiles sports using motivational constructs. The proposed constructs are shown to have implications for marketing managers, advertising agencies, and other researchers in sport marketing.
