Intertextuality is when one media text references another in order to appeal to a target audience or for advertising purposes. In music videos, artists use intertextuality by mixing different media texts that would interest their target viewers. For example, Lady Gaga's "Paparazzi" music video features newspaper headlines about the singer that relate to the song lyrics. While the newspapers may not match the target demographic of 18-24 year olds, they fit the theme of the video. Similarly, Katy Perry's "Last Friday Night" references the fictional social media site "Friendplace" to appeal to its young teenage target audience. Using familiar social media sites helps attract and engage the intended viewers of a music video.
