This paper examines Croatian media pluralism policy in relation to the context of its implementation in a post-socialist Mediterranean media system. Croatian media policy is examined in relation to external, internal, and received diversity at the structural and content levels. In line with this media pluralism policy instruments related to market concentration, media content, diversity in the types of program functions, genres and ideas in media programs, and public service television regulation as an example of internal structural diversity (Hallin & Mancini, 2004) are being examined. In addition, the analysis of received diversity focuses on the role of media audience in the policy framework. The study aims at contributing to the development of the media policy dimension in a comparative media system framework (Humphreys, 2012). To this end it is expected that it will contribute to a better understanding of different policy arrangements in relation to media pluralism in different European countries.
