This paper is focused on the part of the public sphere, where various ethnic, national and language minorities participate – in the sphere of the media. This article draws attention to one aspect of pluralism- namely cultural pluralism, which assumes that the media provide a guarantee of cultural heterodoxy in a given society. This article has three main aims. The first is to draw attention to how cultural pluralism is implemented by the public service broadcasters in two selected countries, both new EU member states - Poland and Slovenia. Moreover, the paper shows how the media in these countries implement the principle of cultural pluralism, particularly in the context of the presence of minorities in the media. The second aim is to examine the extent to which public service broadcasters in these countries create imagined communities. Finally, the third aim is to draw attention to how public broadcasters have adapted to the new situation and how new ethnic groups are recognized by television in Poland and in Slovenia.
