I also don’t remember how long this was a case but there was a period where Scrabble and Classic Concentration were both airing in the afternoon; I want to say it was during Scrabble’s last season. (At least Scrabble did; maybe the false memory is at work.)
Things started getting a little murky with WNBC in the early '90s and the daytime schedule....In spot-checking January 1990 - The "Golden Girls" and "227" block, usually at 11am, aired at 9. "House Party" at 10, "Win, Lose or Draw" at 11 and "Generations" at 11:30. "Santa Barbara" at noon. 1 and 2 were in-pattern, and 3 was "Classic Concentration" followed by "Scrabble" at 3:30.
EDIT: In diving down the rabbit hole even further, that was not the original schedule: when the news broke in November that this was happening (effective January 22), the plan was to have "Santa Barbara" at 11, "Generations" at noon, "Days of our Lives" at 12:30, "Another World" at 1:30, and then a 90-minute game show block starting with "Third Degree" at 2:30. I guess "Third Degree" tanking changed those plans.
