Media in The Simpsons

Media is a recurring theme of satire on The Simpsons. The show is known for its satire of American popular culture and especially television culture, but has since its inception covered all types of media such as animation, journalism, commercials, comic books, movies, internet, and music. The series centers on a family and their life in a typical American town but the town of Springfield acts as a complete universe. The town features a vast array of media channels—from kids' television programming to local news, which enables the producers to make jokes about themselves and the entertainment industry.

Most of The Simpsons media satire focuses on television. This is mainly done through three characters: Krusty the Clown, Sideshow Bob, and Troy McClure, performers in fictional television programs within The Simpsons. The Itchy & Scratchy Show is a show within a show, which is used as a satire of animation and in some cases The Simpsons itself. Topics include censorship, plagiarism, unoriginal writing, live-action clip shows and documentaries. Kent Brockman, Springfield's principal news presenter illustrates the glibness, amplification, and sensationalism of broadcast journalism. His tabloidization methods include making people look guilty without trial, and invasion of privacy by setting up camp outside people's homes.
