Cultural studies is an academic field grounded in critical theory and Marxist literary criticism. It concerns the political nature of contemporary culture, as well as its past historical precedents, conflicts, and issues. It concentrates on how a particular medium or message relates to matters of ideology, social class, nationality, ethnicity, sexuality, and/or gender. Cultural studies is holistic, combining feminist theory, social theory, political theory, history, philosophy, literary theory, media theory, film/video studies, communication studies, political economy, museum studies and art history/criticism to study cultural phenomena in various societies. Thus, cultural studies seeks to understand the ways in which meaning is generated, disseminated, and produced through various practices, beliefs, institutions, and political, economic, or social structures within a given culture.
