Here I will be exploring two of Roland Barthes' media concept theories - namely, the idea of the "enigma code" within presented media, and the idea of mythologies.
Barthe's enigma code concept is when forms of media (such as television programs, novels etc.) presents the audience with a mystery within the story, which triggers a reaction with the audience by posing questions to them. This draws in their interest about the storyline of the particular piece of media, which makes them feel more involved with what is going on. An example of this use is in crime dramas where the idea of a crime having been committed is presented to us a long way before we know who the criminal is.
The mythologies media concept covers the idea that within the media things which are usually associated together are often presented this way to satisfy the viewers expectations. This tends to fit in with the idea of stereotypical media representation in the way that someone from a particular group is often shown with something their group is stereotypically associated with, such as an older teenager being shown with an alcoholic drink.
