Intertextuality refers to relationships between texts, such as how they influence, reflect, or differ from each other. It creates a sense of continuity and reality by allowing works to reference society and other media. For example, The Simpsons uses intertextuality to relate current events to viewers and potentially spark controversy. Eminem also employs intertextuality in his music videos by referencing familiar themes like superheroes and including elements like titles and countdowns that build intrigue and encourage viewers to watch his full videos.
