Before Sesame Street, successful children's programs were entertainment oriented and appeared on commercial television; educational programs were thought to be boring and pedantic and appeared on public television which garnered a small, more affluent audience. Co-creator Joan Ganz Cooney recognized that television could do more than entertain; it could provide supplementary education at a fraction of the cost of classroom instruction. She demonstrated that quality educational programming could attract and hold a mass audience and established an organization which continues to produce innovative programming for all ages. And, via Sesame Street a larger, more diverse audience discovered public television, bringing it to the forefront of the national consciousness.
Sesame Street first aired in November 1969, on nearly 190 public and commercial stations, and by all measures has been a continuing success. In large scale studies, the Educational Testing Service of Princeton concluded that Sesame Street generally reached its educational goals. The show also rapidly gained a mass audience, which it currently maintains.
