Sesame Street
Production
In 1967, when Cooney and her team began to plan the show's development, combining research with television production was, as she put it, "positively heretical". Shortly after creating Sesame Street, its producers began to develop what came to be called "the CTW model", a system of planning, production, and evaluation that did not fully emerge until the end of the show's first season. According to Morrow, the CTW model consisted of four parts: "the interaction of receptive television producers and child science experts, the creation of a specific and age-appropriate curriculum, research to shape the program directly, and independent measurement of viewers' learning".
