The Electric Company, created by the Children's Television Workshop, was on in the morning about five times a day. In the middle of it they would often have a Spiderman segment which featured live-action mixed with animated backgrounds and thought balloons. It ended in 1977 but the final two seasons aired in reruns until 1985. Its most famous regular is none other than Morgan Freeman.
The Electric Company employed sketch comedy and various other devices to provide an entertaining program to help elementary school children develop their grammar and reading skills. Since it was intended for children who had graduated from CTW's flagship program, Sesame Street, the humor was more mature than what was seen there.
