I saw RHODA at #1 and was immediately baffled, like, "Geez. I didn't expect her show to be that popular!" But then I remembered her wedding episode that shot the ratings through the roof.
RHODA was higher rated in its first two seasons than its parent series, but that didn't last too long -- RHODA just had no central identity.
The above listing for October 1966 contains the very first airing of THE GREAT PUMPKIN at Number One (the previous December 1965, A CHARLIE BROWN CHRISTMAS was Number 2).
I was surprised GUNSMOKE was still in the weekly Top 10/15 at this point (the infamous Bette Davis episode aired 1 October 1966, prior to this list); because GUNSMOKE dropped to 35th place by the spring of 1967 and was cancelled (again, but that didn't last long -- again). They moved the western from Saturdays to Monday nights by fall of 1967, and it rebounded into the Top 10 again. (35th place was high enough to keep most series on the air, but I guess the CBS board figured that GUNSMOKE, Number One for years and almost always in the Top 10, must be slipping after a dozen years on the air; William Paley reversed the board's decision, but cancelled GILLIGAN'S ISLAND to make way for GUNSMOKE on Mondays).
