This document defines intertextuality as when a media text references another text such as a film, TV program, or painting. It provides the example of a Cadbury chocolate finger advertisement that references the TV show Dallas through its three panel introduction style, typography, and mid-shots of characters. Elements that can signify intertextuality include conventions from the original text, mise-en-scene, technical conventions like camerawork and editing style, and the use of parody, pastiche, or homage. Intertextuality pleasures audiences by making them want to watch more, privileging those who understand references, and nostalgically reminding them of the past.
