Since the beginning of the twenty-first century, scholarship on the categorisation of media systems and their articulation with political systems has been focused on the three models proposed by Hallin and Mancini (2004) to classify media systems in 18 countries of Europe, the United States, and Canada. These are the liberal model, characterised by the dominance of the commercial media and the market; the democratic corporatist model in which media belonging to social, political, and commercial groups coexist with a limited role of the state; and the polarised pluralist model which combines a partisan press, a weak commercial development of the media and a strong role of the state. This last model has been considered by Hallin and Papathanassopoulos (2002) as the one that best describes the media systems of Mexico, Brazil, Portugal, and Colombia. These countries are characterised by a low level of newspaper circulation, partisan journalism, a high instrumentalisation of the media due to clientelism, and a weak public regulation of the private sector favouring the consolidation of monopolies.
