The expansion of the Internet and the rapid advancement of media technologies have resulted in the democratisation of cultural production. Fans of popular media properties have taken advantage of this, using the tools available to them to create a wide range of works based on their favourite books, television shows, films, and videogames. A major obstacle faced by these fan-creators is the absence of any firm legal principles that deal explicitly with the production of fan works, relegating their activities to something of a legal grey area. Various fan communities have responded to this by developing their own set of norms for regulating the production of fan works. This article elaborates upon these norms, and highlights the way in which they are capable of alleviating creators’ and rightholders’ concerns regarding the potential negative consequences of fan works. It also suggests that these norms may be profitably incorporated into the business practices of the creative sector, and also considers how these norms may inform the future development of copyright law.
