The economic impact of sport in the European Union keeps on growing year by year, as confirmed by the statistics data of the European Commission: already in 2004 proceeds from sport represented 3.7% of EU Gross Domestic Product with 15 million persons employed in the sports sector, which is 5.4% of the labor force in the European Union. This would explain the increasing attention the European Commission is giving to regulating sport activity, and, thus, the growing number of cases in which parties contest certain sport-related rights, in particular media rights acquisition, ticket sales arrangements, sporting rules, and transfer regulation.
