Phonograph Allowed Middle Class to Bring the Show to Their "Castle," Like Kings Already Could
(p. 218) Once Edison's marketers squarely addressed the urban middle class, they devised advertising that made prospective customers feel as entitled to enjoy the pleasures of recorded music as anyone. "When the (p. 219) King of England wants to see a show, they bring the show to the castle and he hears it alone in his private theater." So said an advertisement in 1906 for the Edison phonograph. It continued: "If you are a king, why don't you exercise your kingly privilege and have a show of your own in your own house."
