Purpose-The purpose of this study is to assess the effectiveness of field sponsorship through sponsor recall and recognition across two environments that differ on the degree of felt presence they trigger among viewers: on-site and television. A series of research hypotheses concerning the interaction effects of viewing environment, event-sponsor congruence, and arousal intensity were developed. Design/methodology/approach-In order to test the effect of the viewing environment, a field experiment was conducted where 44 ice hockey fans attended a professional ice hockey game in the local team's arena whereas 44 others saw the same game, at the same time, on television. The participants were randomly assigned to one of the two game viewing conditions. Findings-A higher level of arousal was detrimental to sponsor identification in a manner consistent with the intensity of processing principle according to which arousal polarizes attention resources on the arousing stimulus (the event) while diverting resources away from the peripheral stimuli (the sponsors). In addition, because event congruent sponsors are more superficially processed in comparison with incongruent ones, this negative impact was more pronounced for the former group. This was qualified by a three-way interaction with the type of environment; the on-site, direct, audience was less affected by the processing intensity principle and exhibited better recall and recognition than the television audience as arousal and congruency increased whereas, at lower level of arousal, higher event-sponsor congruence hampered on-site sponsor identification in comparison with television. Research limitations/implications-The findings were obtained in the context of a single sports event; additional studies need to be conducted using different sports. In addition, the comparison of on-site audience with other types of media audiences (e.g., on-line broadcasting) is warranted. Practical implications-Arousal intensity results from the game's drama which is a function of game importance and game outcome uncertainty. Hence, except for low stakes games (e.g., preseason matches, exhibitions), initiatives that promote a leveled playing field such as salary cap, financial fair play, and open leagues are likely to jeopardize sponsor identification, particularly for congruent sponsors. With respect to the impact of the viewing environment, congruent sponsors should reap superior benefits from the television audience when stakes are low. However, when stakes are high, their benefits will accrue to a greater extent from on-site spectators. Originality/value-This is the first study to offer a rigorous comparison of sponsorship's impact on direct (on-site) versus indirect (television) audiences through a field experiment. This is also the first research to provide a framework based on the processing intensity principle that encompasses predictions related to arousal and its interaction with event-sponsor congruence and the viewing environment. Within this perspective, the degree of ...
