Theory: GLARN

Genre... Media products can be classified into categories or genre. A genre can be recognised by its common set of distinguishing features. These features associated with a genre's style and content may be, for example, a particular setting, character types, technical codes. 
Audiences recognise these features and therefore expect certain things. For example, at the end of a romantic comedy film the two lead characters will realise they are in love. Audiences may even select a text on the basis of its genre.

Language... Media language is the way in which the meaning of a media text is conveyed to the audience. One of the ways Media Language works is to convey meaning through signs and symbols suggested by the way a scene is set up and filmed. Signs and symbols in media texts are polysemic which means they are open to many interpretations. 

Audience... Audiences have a complex relationship with the products they consume. Media producers intend audiences to read their product in a certain way, but in actual fact everyone 'reads' and enjoys a product differently due to the individual's background and lifestyle.
Media audiences may be consuming different types of media at any one time (such as listening to an iPod, watching TV, chatting on the Internet) and be engaging at different levels – for example, the television may be turned on whilst a family has dinner.
Media consumers are organised into identified groups (based on such things as lifestyle or earning power) by producers, broadcasters, and advertisers who can then target consumers.

Representation... Media representations are the ways in which the media portrays particular groups, communities, experiences, ideas, or topics from a particular ideological or value perspective. Rather than examining media representations as simply reflecting or mirroring "reality," we examine how media representations serve to "re-present" or to actually create a new reality.

Narrative... The study of narrative explores the different ways that media texts can tell a story. Narrative is strongly linked to the audience and purpose of the text.
Conventions used to tell the story are dependant on the medium. In film, for example, the condensing of time is important and may be shown through production techniques such as camera fades. Whereas in a magazine article narrative conventions include production techniques such as layout and writing, and style is very important.

I will use the GLARN theory when analysing media products / when doing textual analysis'.
