Cultural Media Theory focuses on the reciprocal relationship between media and culture, emphasizing how media both reflects and shapes societal values, identities, and power dynamics. Drawing on Jean Baudrillard’s concepts of simulacra and hyperreality, this theory examines how media representations construct and perpetuate cultural norms. This chapter explores how media has historically shaped cultural narratives, from the idealized portrayals of family life in mid-twentieth-century television to the commodification of culture through advertising. In the digital era, platforms like Instagram and Netflix amplify these dynamics, offering both opportunities for cultural diversity and risks of homogenization. Cultural Media Theory provides critical tools for analyzing the intersectionality of race, gender, class, and sustainability within media narratives, encouraging readers to think critically about representation and identity in a media-saturated world.
