This was a must on Saturday morning. I wouldn’t find out till later but…Ted Knight did some of the dialogue such as “Meanwhile, at the Hall of Justice…” I think the first year (16 episodes) was the best. Altogether the show was on and off during its 13-year run and they ended up with 109 episodes.
Super Friends was produced by Hanna-Barbera in 1973. The show brought all the DC superheroes together and it told their stories. The first season was comprised of only 16 episodes, which were re-run through August 1974. The show was then canceled. Presumably from less than anticipated ratings.
The success of the Wonder Woman TV show in 1975, and probably the early development interest in the Superman movie led ABC to reconsider Super Friends. The original 16 episodes were re-run beginning in early 1976, while production began on a new series. To help promote the new series, DC also began publishing a Super Friends comic. While the stories there were independent of the show, they followed much the same style of the original series.
Beginning in mid-1977, E. Nelson Bridwell, writer of the Super Friends comic, learned of some of the cast changes (notably, the replacement of Wendy and Marvin with Zan and Jayna) after working on the book for several months and wrote the change into his stories, so by the time the new season of the show began in September 1977, the comic had already made the transition to the new characters.
The comic only survived until mid-1981, while the show continued into 1982. However, the show was only re-runs for the 1982-83 season and was canceled outright in the fall of ’83. The show was brought back again in 1984 and ran until September 1986.
