Sitcoms have always been a successful genre dating back to the 1950s. However, in the 1970s, sitcoms really began to hit their stride. If one were to look at a list of the most successful sitcoms of all time, there is no doubt that they would find quite a few of them from the 1970s.

The television landscape was changing in the 1970s, and sitcoms reflected it. Several shows began to explore heavier, more controversial topics that contemporary viewers would not even think twice about today. As a result, several 1970s sitcoms had a lasting effect on the genre and are memorable in their own right.

All in the Family followed the Bunker family, led by the patriarch Archie, a working-class family in the 1970s. Archie often bumps heads with his liberal son-in-law Mike over various topics affecting the United States at the time. The series was groundbreaking for tackling issues such as racism, homosexuality, rape, religion, and abortion across its run.

Currently, All in the Family holds the distinction of having the most spin-off shows, with five. The longest-running one was The Jeffersons, led by the Bunker's former neighbors George and Louise Jefferson, which ran for eleven seasons. All in the Family essentially continued with the spin-off Archie Bunker's Place, which ran another four seasons after All in the Family ended.

The show also successfully made the transition from comedy to dramedy. In the early seasons, a lot of the humor came from the cast's hijinks, pranks, and camaraderie.

Fawlty Towers premiered on BBC in 1975 and featured John Cleese as a hotel owner who tries to run his hotel amidst increasingly demanding and eccentric guests staying at the hotel. The show has the unique distinction of only running for twelve episodes across two seasons, one in 1975 and the other in 1979.

It's a shame that Fawlty Towers did not go longer, given all its success.

1 Happy Days Introduced The Fonz And Jumping The Shark To Pop Culture

Happy Days

Happy Days was one of the staples of 1970s television. Richie Cunningham and his family live in the Midwest in the 1950s and 1960s. In addition to Richie and his family, the show also introduced Arthur Fonzarelli, or "the Fonz," played by Henry Winkler. The show ran for 11 seasons and was one of the most successful sitcoms of all time.

One of the ways the show impacted sitcoms forever was with the phrase "jumping the shark." In season 5, while visiting Los Angeles, Fonzie is challenged to jump over a shark on water skis, which he does with great success. The phrase "jumping the shark" was born, referring to when a show has lost its appeal and does something outlandish in order to drum up ratings or attention.
