The Real Ghostbusters Merchandise Wave was based on The Real Ghostbusters and later elements of Slimer! as it was aired with the show as a hour block. It ran from 1986 through 1991 with some elements such as Now Comics and Ecto-Cooler going on into the middle nineties. While it was based on the cartoon, some elements from the films would be referenced in items. The Ghostbusters II Film Merchandise Wave would share promotional merchandise with some of this wave during 1989 and 1990.
