This document discusses key concepts from Marxist theory and its application to media and cultural studies. It covers neo-Marxist thinkers like Gramsci, Althusser, the Frankfurt School, and Stuart Hall. Some main points are that Marxism views the media as representing the interests of the ruling class and disseminating dominant ideologies, but that neo-Marxists allow for some autonomy and ideological struggle. Hall also argued that audiences can read media texts in dominant, negotiated, or oppositional ways.
