Relationship marketing has become a fundamental concept within modern marketing thought. Some authors even suggest it is the fundamental concept. Its rise to prominence has seen it become a unifying force within the marketing discipline given its application to a whole range of areas. It promises benefits to organisations that can be distilled down to greater profits over the longer term, with less cost. The focus of relationship marketing is relatively simple. Rather than acquiring customers, the retention and development of customers is emphasised. Regrettably, the implementation of relationship marketing is not as straightforward as its definition. It requires at the very least a long-term outlook, an embracing of technology and a commitment to a customer focus. If relationship marketing is such a critical element in modern marketing, it follows that its application across industry sectors be examined. Sport is one such industry and has coincidentally emerged as a major business sector in the same time-frame as relationship marketing's maturity. As the markets for sport have grown, so too has the sophistication of the sport marketer. From amateur, myopic beginnings, sport continues to claim a strong grip on the cultural identity of countries such as Australia. Buoyed by strong media interest, attendance at sporting events continues to grow, albeit across a much larger choice-set. The road ahead is not necessarily bountiful however. Information presented in Chapter 1 of this thesis suggests that the frequency of individual attendance at major sports in Australia is declining, despite some positive overall attendance figures. In essence, it appears that loyal customers are being replaced by newer, less committed ones. While this might not be instantly damaging, it does require sport marketers to ensure that strong levels of identification with their products are developed. All of this is supported by the existing literature that has recognised that sport can likely benefit greatly from the implementation and application of relationship marketing, but is in urgent need of further study. These scenarios suggest a need to understand where relationship marketing in sport currently rests and this thesis answers the call and asks the following research questions: RQ1) To what extent do professional sporting organisations in Australia undertake relationship marketing; RQ2) what strategies do they employ and RQ3) what are the issues faced in implementing a relationship marketing approach? This thesis takes an organisational perspective, across multiple-cases in major professional sport and considers the sport-consumer relationship exclusively. It is the first study of its kind in this area and adds significantly to the body of knowledge, both within sport marketing and the broader concept of relationship marketing. It indicates that while relationship marketing is acknowledged and indeed welcomed as a concept by practitioners, their efforts at implementation have been primitive, largely unplanned and generally sporadic. More than often they reflect a reactive rather than proactive strategic approach. A range of barriers are presented and discussed as are some examples of organisations that have incorporated some parts of a relationship marketing philosophy into their structure. A conceptual model in the final chapter of this thesis synthesises the issues extracted from the various cases and existing literature. It depicts a challenging road ahead for professional sport organisations.
