We selected ten post-communist countries for this research. Eight of them are located on the Balkan Peninsula, from a geographical point of view. We added Romania and Slovenia for historical reasons. The main aim of research is to provide a model of the media system in each of them. We are interested in the political, societal, economic and technological situation, journalistic standards and media accountability. The important thing is to know how media systems evolve in each country, under the influence of political institutions and external stakeholders. We examined how political, media, economic and social systems co-work or influence each other and how they affect each other.
