The greatest Saturday morning ever? Quite possibly. It was September 6, 1975 when the TV networks pulled out all the stops to grab a sci-fi loving audience, hungry for entertainment (and product tie-ins). Relive the moment that Filmation, Krofft, Hanna-Barbera, and Ruby-Spears ruled the airwaves.

Follow Sci-Fi 5 for your daily dose of science-fiction history.
