Pulled along by a string behind an interested toddler, Fisher-Price's Chatter Telephone was the company's best-selling product through much of the 1960s and '70s. With noisemaking buttons and dials, the telephone inspired young children to mimic their parents' actions on the phone, and most of all, it inspired them to speak. Introduced in 1962, the original Chatter Telephone was made of wood; today it's made of plastic. Some modernizations of the old-fashioned-looking phone have been attempted, but at the rate changes in communication technology are going, any relevant iteration today would have your child asking you if there's an app for it.
