As the commercialization of sport grows, the need for proper regulation increases. In legal terms, sport is part of the entertainment and media industries which are subject to rapid change. This work brings together experts in many fields to analyze these changes and to discuss the implications of issues such as the BSky B-Manchester United case, civil and criminal actions on the playing field, the "Bosman" ruling, drugs in sport, the legality of boxing and the validity of decisions made by governing bodies. This collection should appeal to students of both sports history and sports sociology.
