The document discusses several theories related to audiences and media studies: 1) Maslow's Hierarchy of Needs proposes that humans have physiological, safety, love, esteem, and self-actualization needs that must be met. 2) Passive audience theory suggests that media can directly "inject" ideas and beliefs into audiences who passively accept messages. 3) Cultivation theory argues that prolonged TV watching can shape viewers' perceptions of social reality through repetitive exposure to certain ideas. 4) Two-step flow theory posits that media messages pass from media to opinion leaders and then to the general public rather than directly to audiences.
