The "Frankfurt School" refers to a group of German-American theorists who developed powerful analyses of the changes in Western capitalist societies that occurred since the classical theory of Marx. Working at the Institut fur Sozialforschung in Frankfurt, Germany in the late 1920s and early 1930s, theorists such as Max Horkheimer, T.W. Adorno, Herbert Marcuse, Leo Lowenthal, and Erich Fromm produced some of the first accounts within critical social theory of the importance of mass culture and communication in social reproduction and domination. The Frankfurt School also generated one of the first models of a critical cultural studies that analyzes the processes of cultural production and political economy, the politics of cultural texts, and audience reception and use of cultural artifacts (Kellner 1989 and 1995).
Moving from Nazi Germany to the United States, the Frankfurt School experienced at first hand the rise of a media culture involving film, popular music, radio, television, and other forms of mass culture (Wiggershaus 1994). In the United States, where they found themselves in exile, media production was by and large a form of commercial entertainment controlled by big corporations. Two of its key theorists Max Horkheimer and T.W. Adorno developed an account of the "culture industry" to call attention to the industrialization and commercialization of culture under capitalist relations of production (1972). This situation was most marked in the United States that had little state support of film or television industries, and where a highly commercial mass culture emerged that came to be a distinctive feature of capitalist societies and a focus of critical cultural studies.
During the 1930s, the Frankfurt school developed a critical and transdisciplinary approach to cultural and communications studies, combining political economy, textual analysis, and analysis of social and ideological effects of. They coined the term "culture industry" to signify the process of the industrialization of mass-produced culture and the commercial imperatives that drove the system. The critical theorists analyzed all mass-mediated cultural artifacts within the context of industrial production, in which the commodities of the culture industries exhibited the same features as other products of mass production: commodification, standardization, and massification. The culture industries had the specific function, however, of providing ideological legitimation of the existing capitalist societies and of integrating individuals into its way of life.
