Well, heck, I guess you can learn something new every day. In 1975, Filmation produced a live-action series titled Ghostbusters. The series ran on CBS for two official seasons and eventually the name "Ghostbusters" was forgotten until the box office smash with the same title hit screens in 1984.

Folks around my age probably remember The Real Ghostbusters, a cartoon spun off from the movie with the clever hook that they were the actual Ghostbusters, and the guys in the movie were just actors. At the same time, however, after having settled out of court with Columbia Pictures for using the name, Filmation decided to try and cash in on the name by making a cartoon titled The Original Ghostbusters, which featured the sons of the original CBS series taking up the business once again.
