The Invention of the Teenager

 As the cultural landscape around the world shifted during the industrial revolution, and with a growing gap between adults and youth, the concept of a new generation took shape: teenagers. Director Matt Wolf discusses his documentary “Teenage,” a rumination of the creation of youth culture from the end of the 19th century to the first half of the 20th, adapted from Jon Savage's bestselling 2007 book of the same name. “Teenage” opens March 14 at the Lanmark Sunshine Cinema.
