In mid 1970s the Saturday morning television landscape consisted of cartoons and a variety of live action series based on action adventures and superheroes. Networks scrambled to take the formula laid out by Sid & Marty Krofft and adapt it for their own machinations.
This resulted in the creation of a plethora of cult TV shows that never got to really extend themselves beyond a few episodes or a full season. The networks were antsy and the ghouls in suits had neither qualm nor problem with pulling the plug on a show that didn’t get ratings or ad money straightaway.
Granted, upon hindsight many of the shows were putrid and really did deserve to go. However almost forty years later some of these shows (Shazam, Isis, Jason of Star Command) have managed to retain a nightmarishly loyal cult following.
