In 2012 London becomes the first city to host an Olympics for the third time. The contrast between the Games of 2012 and those of 1908 and 1948 could not be starker and form a background to some of the matters discussed in this short piece. Central to the discussion is the contention that the development of the body of law now known as sports law is related to the accelerated commercialisation of sport during the past century. In short, the business of modern sport is exactly that – a business; indeed, sport is now a global industry and the commodification of sport will be seen to an exaggerated effect in London throughout the summer of 2012. Accordingly, this article by Jack Anderson begins by giving an outline of the financial robustness of modern sport, epitomised by the Olympics, before presenting a brief history of the evolution of sports law. Thereafter various issues in contemporary sports law are identified and discussed. The conclusion attempts to bring all of these themes together in order to give an overview of the area as a discrete, vibrant, if still emerging, discipline of law.
