The "The Ewoks and Droids Adventure Hour" was opposite "Muppet Babies" and "Hulk Hogan's Rock 'n Wrestling" on CBS, and the "Smurfs" and "Its Punky Brewster" on NBC. (over the course of the 1985-86 season)
ABC also was moving when the "Ewoks/Droids Adventure Hour" was from Fall, Winter, and Spring, probably to get away from those rival shows. In March they might have managed to get a half-hour of it in to a spot with the other networks doing reruns of "Richie Rich" (CBS) and "Alvin and the Chipmunks" (NBC), but it was likely too late by then.
In 1986-87 ABC has just "The All New Ewoks" for a half-hour ("Droids" was gone). It was against "The Puppy's Great Adventure", "Richie Rich", "CBS Storybreak", (CBS) and "Foofur", and "Its Punky Brewster" (NBC).
