Until now, discussions of theories of media and society or media and the state in the North American literature have been limited. The four theories of the press advanced by Fred Siebert, Wilbur Schramm, and Theodore Peterson cover the main approaches of Western liberal society, the libertarian and social responsibility models, and some aspects of the Eastern bloc in the “totalitarian” model. Under the heading of “authoritarian,” however, a number of very diverse systems are lumped together. One major variation seen in Brazil is the continued vitality of the corporatist model of state and society, which has distinct implications for the role of mass media. In particular, aspects of corporatism seem to be combining with aspects of democracy and mass mobilization politics in ways that shed light on the role of the media in constructing or undercutting ideological hegemony in the heterogeneous, class-divided societies of Latin America.
