The document discusses several theories related to audience and media consumption:
1) Uses and gratifications theory focuses on why and how people actively seek out media to satisfy needs, rather than what media does to people. It assumes audiences are active in interpreting media.
2) Stuart Hall's encoding/decoding model examines how producers encode meanings in texts and how audiences can correctly decode, misdecode, or oppose the meanings.
3) The effects theory examines how media can influence behavior but was critiqued for viewing audiences as too passive, unlike uses and gratifications theory which sees audiences as active.
