Role of the Internet Site in the Promotion Management of Sports Teams and Franchise Brands

This study examines the role that a website plays in the development of fan allegiance and as a promotion management tool for a sports team and brand. Research indicates that the combination of sports, media (television in particular), and sponsorships when employed in an integrated manner, can develop consumer connection to brands. This study suggests that the Internet is also an important part of an integration strategy of sports, media, and promotion. By working with a new team in the AIFA indoor football league, the researchers were able to determine what helped make fans allegiant to the team before the franchise's inaugural game. The results show that even before the team played its inaugural home contest, fans had become allegiant to the franchise brand and team by using the team internet site. These results indicate that an internet site can serve as a strong promotional tool in an integrated marketing plan of sports, media, and promotion to move fans toward brand loyalty and toward primary goals of the firm, including increased sales.

Satellite fans: Does sport nostalgia influence purchase intention toward sponsors’ products?

The purpose of this study was to investigate how nostalgia influences their attitude towards the European Professional Football Leagues (EPFL) sponsors and purchase intention towards EPFL sponsors' products. Based on a convenience sampling, a total of 317 EPFL fans in Singapore responded to an online survey that included items on sport nostalgia, attitude towards EPFL sponsors, and intention to purchase EPFL sponsors' products. Data were analysed using confirmation factor analysis (CFA) and structural equation modelling (SEM). The results showed that sport nostalgia had a direct positive effect on both attitude and purchase intention towards EPFL sponsors’ products. Also, this study found that sport nostalgia had a significant indirect effect on purchase intention through attitude. From the findings of this research, sponsors could understand the role of sport nostalgia and would be able to implement marketing strategies that direct their consumers to purchase their products.

Superstars as Drivers of Organizational Identification: Empirical Findings from Professional Soccer

This paper examines the effect of superstars on external stakeholders’ organizational identification through the lens of sport. Drawing on social identity theory and the concept of organizational identification, as well as on role model theories and superstar economics, several hypotheses are developed regarding the influence of soccer stars on their fans’ degree of team identification. Using a proprietary data set that combines archival data on professional German soccer players and clubs with survey data on more than 1,400 soccer fans, this study finds evidence for a positive effect of superstar characteristics and role model perception. Moreover, it is found that players who qualify for the definition of a superstar are more important to fans of established teams than to fans of unsuccessful teams. The player's club tenure, however, seems to have no influence on fans’ team identification. It is further argued that the effect of soccer stars on their fans is comparable to that of executives on external stakeholders, and hence, the results are applied to the business domain. The results of this study contribute to existing research by extending the list of personnel‐related determinants of organizational identification.     

A tale of two audiences: Spectators,television viewers and outcome uncertainty in Spanish football

This paper tests for the impact of match outcome uncertainty on two types of audience for Spanish football, fans at the stadium and television viewers. We find that fans inside the stadium prefer games that are less and not more likely to finish with a close score. This is contrary to much theoretical literature in sports economics which argues that fans prefer close contests and imposes this assumption in formal modelling. We also find that television viewers prefer close contests to more predictable contests. The different preferences of fans inside the stadium and television viewers need to be reconciled by the league when considering the effectiveness of policies to redistribute resources amongst teams in the league. We use our empirical model to consider how this tension might be resolved so as to maximise total audience and total league revenues.     

Customer retention in sports organization marketing: examining the impact of team identification and satisfaction with team performance

Over the past two decades, relationship marketing efforts have assumed a prominent role in sports organization marketing. A sports organization that successfully implements relationship marketing programmes is able to develop long‐term relationships with its fans, thus increasing the likelihood of customer retention. This study examines customer retention in sports organization marketing by considering the impact of team identification and satisfaction with team performance on four fan consumption behaviours: in‐person attendance, media‐based attendance, purchase of team merchandise and word‐of‐mouth communication related to the team. Survey data were collected from 300 fans of more than 40 professional and collegiate teams involved in seven sports. Results suggest that both team identification and satisfaction with team performance impact multiple consumption behaviours, as represented by fans' intentions to engage in future consumption. Team identification was found to have the greater impact on consumption behaviours, suggesting that a sports organization's continuing efforts to bond with its fans may provide greater benefits than efforts to improve the team's competitive performance.
