The game shows that were on WPIX from 8-10pm were run on a somewhat haphazard way. They were often pre-empted by Yankees games, movies, specials, etc. As I recall, they had TTD, LMAD reruns, YDS!, Garagiola TTTT (long after they ended production) and Celebrity Charades. Since none of those shows had a barter component, Channel 11 had the ability to schedule them as needed. I live in Michigan, so the way I got these listings was by subscribing to a magazine called Cue New York. They are archived in Google Books if you want to look at them. I started getting the mag in early 1979. By the fall of 79, WPIX changed their prime time lineup, with Jim Rockford, Private Investigator taking the 8pm slot.
