'Killer lineup' on CBS ruled the '70s
When people talk about Saturday night TV, the discussion almost always comes back to CBS' lineup in the early- to mid-'70s, when as many as five classics shared the same evening. From 1972 to 1975,
All in the Family, The Mary Tyler Moore Show, The Bob Newhart Show and The Carol Burnett Show were Saturday neighbors, with M*A*S*H in the lineup for the 1973 season. All in the Family was TV's top-rated show during those years, with Moore's sitcom often in the top 10.
