In this major new work, Thompson develops an original account of ideology and relates it to the analysis of culture and mass communication in modern Societies. Thompson offers a concise and critical appraisal of major contributions to the theory of ideology, from Marx and Mannheim, to Horkheimer, Adorno and Habermas. He argues that these thinkers - and social and political theorists more generally - have failed to deal adequately with the nature of mass communication and its role in the modern world. In order to overcome this deficiency, Thompson undertakes a wide-ranging analysis of the development of mass communication, outlining a distinctive social theory of the mass media and their impact.
