The Electric Company

This show displayed a variety of sketches that uses comedy and other means of interest to children about education. I remember seeing this show in the early 80s in syndication on PBS. What I've remembered enjoying on the show was a cartoon named Letterman. In which this little superhero teaches grammer with vowels and prepositions and how they are used in a sentence. I also remember the Spiderman episodes. I had to be around six or seven when this show was aired,though the other segments on the show I vaguely remembered. But if someone had mention this show to me I would remember it as if it was yesterday because of the impact it put on me as a child.
