Representation

 Representation.

In earlier theories of representation, people thought that everything has a true meaning, which can then be changed and represented by the media in different ways. However in Stuart halls view, he shows that most issues don't have a true positive or negative meaning, as these meanings are created by the media with the views and opinions of the people who create it. This itself can have varying consequences, as media can inevitably influence the opinions of some of the people who consume it. This can lead to peoples opinions on even groups of people changed, which can lead to hatred and violence if media is used for this purpose. These media productions are often created by the hegemonic (or socially and politically dominant) groups in society. 

Reality->Mediation->Media

Mediation is the filter that reality goes through to be re-presented as a media product. Media produces are there'll called the mediators.
