This document summarizes the theories of several postmodern theorists: - Barthes explored semiotics and how meaning is interpreted based on audience experience and culture, allowing for multiple meanings. - Hall examined how audiences can have hegemonic, negotiated, or oppositional readings of texts based on their relationship to the producer. - Jameson argued that postmodernity has lost connection to the past and focuses on exaggerated replicas and entertainment over meaning. - Foucault discussed panopticism and how society is structured to encourage constant surveillance and watching of others. - Denzin analyzed how postmodernity blurs past and present, uses blunt statements, and presents the unpresentable through sexuality and violence.
