This document discusses the concept of "moral panics" that involve youth subcultures. It provides examples of moral panics in the 1920s and 1950s in America that targeted youth behaviors like necking, smoking, and disrespect towards authority. These panics were fueled by anxieties among parents about social and technological changes as well as fears about the influence of the media on youth culture. The document also reviews the origins and key characteristics of the concept of "moral panic" as defined by sociologists who study youth subcultures and media representation.
