Theories

1) "The cultivation theory" (Gerbner), the idea that films don’t show what we want to see, but makes  us want to see what it wants through exposure of what they want multiple times.Plus tv is a medium of socialisation, so we get taught how to act through what we see.

2)The regulatory framework of contemporary media with a focus on PSB (Public Service Broadcasting.For an example The killing looks at gender stereotypes and women’s rights helps people become aware of these things through their show.

3)"Cultural Industries theory" from Hesmondhalgh is the idea that the cultural i industry includes vertical and horizontal integration. Vertical integration is when a business like a clothing shop also owns the manufacturing company that produces the wool for their business and horizontal integration is when the the shop promotes their business through tweets. Also synergy is the coming together of multiple elements.

4)Stuart Hall’s "Reception theory" is about encoding and decoding.Encoding is about how the creator of a product, show, play etc, etc wants you to react whilst decoding is about any other view point.Reviews of The Killing from The Times and The Guardian show  ending and decoding:

• The Times -"Probably the best crime drama in the world”.
• The Guardian - "Classy and Compelling”.
