In this paper it is argued that the concept of pluralism – the most important value in the Italian media debate – is conceptually confused. The author identifies three mutually incompatible conceptions of pluralism used when discussing the public broadcaster Rai: (1) structural pluralism, satisfied when the public broadcaster is divided into autonomous channels or programme groups; (2) summative pluralism, satisfied when output is divided between political actors according to some ideal distribution; and (3) pluralism ‘lottizzato’, satisfied when a number of different political positions are ‘represented’ by journalists within the broadcaster.
