This document discusses three theories of media narrative:
1. Propp's theory argues that all stories share the same internal structure of 8 character roles and 31 functions.
2. Levi-Strauss studied how primitive societies functioned and argued they shared elements with advanced societies. He looked at binary oppositions between groups.
3. Equilibrium theory says all stories are about returning to normality after an event disrupts the equilibrium. It examines what event caused the disruption and how the narrative works to restore balance.
