The All-New Super Friends Hour is an American animated television series about a team of superheroes which ran from September 10, 1977 to September 2, 1978 on ABC. It was produced by Hanna-Barbera and is based on the Justice League and associated comic book characters published by DC Comics.
Even though Hanna-Barbera's first superheroes cartoon series didn't do very well, the popularity of TV's Wonder Woman and The Six Million Dollar Man spurred network interest in reviving the Super Friends program. When it was again unveiled in 1977, more young children and teenagers than before tuned in, making The All-New Superfriends Hour a huge ratings success. The success prompted the ABC television network to plan a new and even more innovative series for the fall of 1978.
In this particular incarnation of the Super Friends, the DC Comic book legends Superman, Batman, Robin, Wonder Woman and Aquaman return to fight for justice. However, this time, they get help from the shape-shifting super-teens Zan and Jayna (a.k.a. The Wonder Twins), along with their space-monkey Gleek.
The All-New Superfriends Hour featured four animated shorts per program which followed a basic format each week.
The first segment of every show featured two of the heroes (For the purposes of the team-ups in the first and fourth segments, Batman and Robin were considered 'one hero'.) teaming up in a separate mini story.
The second segment featured a story with the Wonder Twins.
The third segment was considered the "primary" adventure of the week which featured the entire Super Friends roster (including the Wonder Twins) in a longer adventure.
The fourth and final segment featured a story with one of the primary lineup along with a "special guest star." The fourth segment typically featured a problem which was solved using the guest star's unique abilities.
In addition, between segments their were additional short spots with members of the Super Friends giving basic safety lessons, basic first aid advice, magic tricks, and a two part riddle featuring the week's primary plot line.
