The idea

These theories answer one question: how strong is the effect of the media on people? The earliest view, the hypodermic needle or magic bullet theory, saw the audience as passive and the effect as direct, immediate and the same for everyone.

Research then showed limited effects. Lazarsfeld found that personal contact mattered more than the media, and uses and gratifications treated the audience as active choosers.

Later theories found effects that are indirect and long-term. Agenda-setting says the media decide which issues seem important. Cultivation says years of heavy television viewing shape a person's picture of the world. The spiral of silence and gatekeeping explain how some views and some news items never reach the public.

Rules to remember

Common mistake

Agenda-setting is often confused with the hypodermic needle. Agenda-setting does not claim that the media change opinions; it claims only that they decide which issues people rank as important.

Worked example

A student says she watches a drama serial every evening to relax and to have something to discuss with friends. Which theory best explains this?

  1. The statement is about why the viewer chooses the programme, not about what the programme does to her.
  2. She uses the media to meet her own needs: relaxation and social contact.
  3. A theory that starts from the needs of an active audience is uses and gratifications.

Answer: Uses and gratifications.
