Super Friends first aired on ABC on September 8, 1973, featuring well-known DC characters Superman, Batman and Robin, Wonder Woman, and Aquaman as part of its Saturday morning cartoon lineup. It was produced by Hanna-Barbera and was based on the Justice League of America (JLA) and associated comic book characters published by DC Comics. The name of the program (and the JLA members featured with the Super Friends) have been variously represented (as Super Friends and Challenge of the Super Friends, for example) at different points in its broadcast history.
