While M*A*S*H eventually became a huge hit, it wasn’t always successful. In the first season, ratings tanked. Viewers didn’t seem to click with the show, causing the network to doubt their decision to keep it on. Before deciding to cancel the series because of the low viewership the network revived it by moving it to a different time slot.
When M*A*S*H moved to Saturday nights from its old time, after popular show All In The Family and before The Mary Tyler Moore Show. It immediately boosted the ratings of the show, resulting in it keeping its place as one of America’s favorite television programs.
