Family sitcoms from the 1950s to the 1970s differ greatly from the programs offered from the 1980s forward. Identify a family sitcom from before the 1980s and watch an episode. Programs such as Leave it to Beaver, Bewitched, The Partridge Family, and The Brady Bunch are some examples of popular shows that fit the criteria. You should be able to find old episodes of these shows online or as reruns on television.
