The Electric Company

Marvel Comics allowed the show to use the character Spider-Man for free. To commemorate the partnership between Marvel and the Children's Television Workshop, Marvel published a special comic book series called "Spidey Super Stories," which were easy-to-read adventures of Spider-Man that occasionally featured members of the show's cast. A shortened version of the comic, featuring only characters from the Marvel Universe, appeared in "The Electric Company" 's spin-off magazine. There was even a parody in a humor issue of Marvel's "What if...?" called "Spidey Intellectual Stories", where Spider-Man defeats a super-villain by debating philosophy in a story that even the narrator, the Watcher, finds boring.

During the song "Apostrophe S" (sung by Lee Chamberlin), after Lee sings "the hat is Jim's and that's that", a white-sleeved arm appears briefly at the bottom right of the screen.

At the end of every episode is a disclaimer read aloud by one of the cast members stating, "The Electric Company gets its power from the Children's Television Workshop".
