Cincinnati:
To the Wonderama question, yes, it aired on Metromedia 19 (WXIX) on Sunday mornings, 10:30 to Noon (wackadoo, wackadoo!)
Various videos of Cincinnati programming exists at Union Terminal, at the Cincinnati Historical Society. A lot of programming has been donated over the years, being kept in a humidity controlled vault.
WLWT: No kids shows. AVCO/Multimedia produced "Young People's Specials". Also, Steve Douglas and then Claire Slemmer hosted "It's Academic". WLWT was the home of Paul Dixon, Bob Braun, Ruth Lyons, etc.
WCPO: Uncle Al Show. The longest running local kids show until the mid 80's. Followed Captain Kangaroo and had a LONG wait for tickets. WCPO also did "Play It Safe" with a Cincinnati Policeman as host, Juvenile Court (with a University of Cincinnati law professor acting as Judge Paul Trevor).
Uncle Al owns the last two years of Uncle Al Town, which aired briefly on WarnerAmex in the early 90's.
WCPO kept a library of programming. Some still exists.
WKRC: Skipper Ryle. Glenn Ryle did wrap arounds for Mighty Mouse and Bullwinkle. Had skill games, like Beat The Clock, etc. His last show was live from Kings Island and had a huge audience.
WKRC lost a lot of their library in the early 70's
WXIX: The Cool Ghoul (Dick Von Hoene) and Larry Smith Puppets. They kept the station going.
Bits and pieces of their library exists. Some Cool Ghoul material pops up on YouTube every now and then.
WCET: Early years: Skipper Ryle and Larry Smith Puppets
Not much exists prior to 1977, due to a waterline burst on Mt. Olympus years ago.
WBTI/WIII/WSTR: No kids shows that I am aware of.
Storer Cable revived The Magic Forest, which Larry Smith Puppets did on WCET.
