"Bonanza was ... the first show to introduce the ranch, ... as an important element in the narrative, the fifth character, as producers referred to it. Brauer and Brauer argue that this emphasis on the "piece of land" was symbolic of a shift in emphasizing mobility, the lone wanderer, with his gun and horse to a focus on the settled landowner.Brauer, R. and Brauer, D. The Horse, the Gun and the Piece Of Property: Changing Images of the TV Western. Bowling Green, Ohio: Bowling Green University Popular Press, 1975. These changes also led to a restructuring of the leading characters' role in the community."—The Museum of Broadcast CommunicationsMuseum.tv: Bonanza
