Representation

Definition - 

By definition, all media texts are re-presentations of reality. This means that they are intentionally composed, lit, written, framed, cropped, captioned, branded, targeted and censored by their producers, and that they are entirely artificial versions of the reality we perceive around us.

My Definition - 

Media Representation is the way groups are portrayed in the media, often through stereotypical images that affect the views of gender, race, class and age throughout the audience. Which may lead to false reality to pin point different aspects of the media.
