This document discusses Strinati's theories on mass culture and popular culture. It defines mass culture as culture widely disseminated through mass media, and popular culture as activities or products aimed at the general public. There are three main themes in popular culture: its origins, the influence of commercialization and industrialization, and its ideological role. Popular culture is seen as both atomizing individuals and being shaped by mass production and consumption through new media like cinema and radio. Critics argue mass culture theory ignores the diversity and active role of audiences.
