The document discusses various forms of intertextuality in media including pastiche, parody, homage, calque, translation, hybridity, and bricolage. As an example of pastiche, the document analyzes Katy Perry's music video for "Unconditionally", which references Snow White, The Hunger Games, Harry Potter, and Dangerous Liaisons. Parody is described as ridiculing existing works, while homage pays respectful tribute. Examples include Justin Timberlake's homage to Michael Jackson and a parody of Meghan Trainor's "All About That Bass" video.
