Narrative theory analyzes how media texts communicate meaning through stories. A narrative is defined as a chain of events with a beginning, middle, and end that follows a cause-and-effect relationship. Narrative theorists like Branigan and Propp analyzed how narratives embody ideologies and include character archetypes. Barthes identified five codes that help readers make sense of narratives, including action, referential, symbolic, and enigma codes. Levi-Strauss examined how stories reflect a culture's values through binary oppositions. Postmodern narratives are characterized by nonlinearity, self-reflexivity, and pastiche.
