Third in the series. Let's have a look-see at sitcoms we like from the 1970s. At the start of the 1970s, the infamous "rural purge" brought the cancellation of many popular rural comedies, and introduced a new era for the TV comedy. THE MARY TYLER MOORE SHOW, and its eventual spin-offs, were successes for MTM Productions. Producer Norman Lear had a string of hits, starting with ALL IN THE FAMILY, and eventually, with its spin-off MAUDE. The decade also gave us the first truly sitcoms centering on African-American families, like SANFORD & SON and GOOD TIMES. Almost all of the above shows had their homes with CBS, while ABC gave us HAPPY DAYS, LAVERNE & SHIRLEY, and MORK & MINDY the same decade. What's your favorite sitcoms from the 1970s?
