The study of the political, economic, and ideological influences affecting media organizations and their content is usually carried out using the critical perspective of Political Economy. The perspective on the political economy of media is closely related to the broader historical discussions of media as cultural industries put forward originally by the Frankfurt School. The concept of cultural industries and the reflection on the matter have their origin in the Frankfurt School. The essay that gave rise to the concept was “The Culture Industry: Enlightenment as Mass Deception” published in the book Dialectics of Enlightenment by Theodor Adorno and Max Horkheimer. In the case of the North American discussion, the critical current of the media’s political economy followed these debates, contributed their own perspectives including those of Herbert Schiller, Dallas Smythe and Thomas Guback. In Latin America, the political economy approach was the most popular perspective in communication theory classes at undergraduate and graduate programs in communication.
