Answer: Sounds like "Legacy," a series that ran on UPN, which is now part of CW, in 1998-99.
It dealt with the Logan family, including Ned (Brett Cullen), Sean (Grayson McCouch), Clay (Jeremy Garrett) and Alice (Lea Moreno). They all worked on a dirty, smelly farm, and yet they seemed as fresh as models going to a photo shoot!
Answer: "Ethel and Albert" was created and written by Peg Lynch, who also played Ethel. Albert was played by Alan Bunce. It ran on all three networks as a radio show from 1944-50, and on all three networks as a TV show from 1952 until 1956, including a one-season stint as a regular feature on "The Kate Smith Hour." Critics praised the show's low-key humor and its avoidance of female stereotypes.
After its TV run, Lynch took the concept back to radio as "The Couple Next Door," which ran from 1953 into the mid-1960s, ending as a feature on NBC's weekend radio package "Monitor."
As for "Tom Corbett, Space Cadet," it aired on all four networks (including DuMont) between 1950 and 1955. Frankie Thomas Jr. played Corbett, and Jan Merlin was his friend, Roger Manning. Corbett and Manning were students at the space academy who flew around protecting mankind in rocket ships where the controls looked like cardboard boxes with dials stuck on them.
