I want to make a reply on "TVWI: CBS picked up Family Affair on its Saturday Morning schedule" that the ITTL 1971 Saturday Morning CBS schedule was built, and Family Affair running opposite Curiosity Shop on ABC and The Bugaloos on NBC.
As ITTL, Family Affair could be the second PrimeTime sitcom to air on Saturday Mornings, following Bewitched on ABC.
