The document discusses several theories related to film directors, genres, audiences, and media reception:
1) The auteur theory argues that directors impose their personal vision through stylistic elements like camera work. Hitchcock is cited as an example who featured creative techniques.
2) Genre theory categorizes media based on shared iconography and cultural values. Genres help audiences decide what to watch and evolve over time with changing conventions.
3) Audience theories range from the effects model where messages are passively received, to uses and gratifications where audiences actively seek pleasures, to reception theory where messages can be interpreted differently.
