These Are the Days - ABC - September 7, 1974, to September 27, 1975

These Are the Days is an animated television series from Hanna-Barbera, originally broadcast on ABC from September 7, 1974, to September 27, 1975. The series, although critically acclaimed, only lasted 16 total episodes. Each episode had a run time of 30 minutes.
The show was set at the turn of the 20th century, in an old town called Elmsville. It portrayed the everyday lives of the Day family, which consisted of a widow and her three children, along with her father (the kids' grandpa). Each episode featured the various family members and their interaction with friends and neighbors, usually ending with a lesson learned.
The show ran in a similar fashion to the popular television show The Waltons. Along with Devlin it was also one of the very few dramatic series to be produced by Hanna-Barbera, a company known primarily for comedies and action-adventure series. Coincidentally, Warner Bros. now owns the rights to all 3 shows, having acquired Lorimar Productions (which produced The Waltons) and Hanna-Barbera.
