The hypodermic needle model (also known as the hypodermic-syringe model, transmission-belt model, or magic bullet theory) is a model of communication suggesting that an intended message is directly received and wholly accepted by the receiver.

This means that the audience will understand the film completely, as well as the directors messages and values within the film. However, this is not always the case as everyone interprets things in different ways and will see it motifs, themes etc in a different light to others.
The Multistep Flow Model is a theory based on a 1940′s study on social influence that states that media effects are indirectly established through the personal influence of opinion leaders.

Audience theory delves into why people listen to the media and why they are so influenced by it.

It is important to take into account these theories when planning my own music magazine front cover and double page spread.
