The thesis examines American teen dramas on Australian television in the period 1992 to 2004. It explores the use of the genre by broadcasters and its uptake by teenagers in an environment where American popular culture has frequently been treated with suspicion and where there are perennial arguments about the Americanisation of youth and their vulnerability to cultural imperialism. The thesis argues concerns about Americanisation and cultural imperialism in relation to youth culture, young people and the media are misplaced. American teen dramas are investigated as an example of the ways imported programs are made to cohere with national logics within the Australian mediasphere (Hartley, 1996). Utilising Yuri Lotman's (1990) theory of cultural 'translation' this thesis argues teen drams are evidence of dynamic change within the system of television and that this change does not result in a system dominated by imported product, but rather a system that situates foreign programming amongst domestic frames of reference.
