This study aims to analyse the weakening of media and communication monopoly of the Party-State in Ceausescu's Romania and in the context of the growing transnational flow of cultural products during the emerging globalization of the '70s and '80s decades. The three parts of the study are describing this problem: the first part examines the strategy of the cultural policy of the Party-State, seen here as a key phase which guides the conception of the cultural and information offer of products made available on the market. The gradual deterioration of the Romanian cultural policy questions its effects in the offers' development. The second part of the thesis is trying to provide some answers: the official offer shows a decline in quantity and in quality, especially during the '80s, as overburdened by a growing segment of propaganda products. At the same time, it no longer corresponds to the expectations of the public addressed, which asserts itself as an active player in the market, participating among other actors, local or international, in creating an alternative market for cultural and information products. So what is the response of the Party-State in this new competitive environment? Does it have any particular strategy to maintain its monopoly on media and communication? The third part of the thesis explores the instrumental use of the Youth Research Institute in Bucharest as a tracking device in the service of the Party-State to prevent the emergence of an alternative sphere of communication.
