Gibbsville
Released in 1976, the action-drama series ‘Gibbsville’ was about a cub reporter that worked for the Gibbsville Courier in Pennsylvania. The show was set in the 1940s, and NBC had high hopes of it being a hit. Unfortunately, only six out of the 13 produces episodes were ever aired.
A cast that included Gig Young and John Savage as the lead roles weren’t enough to save this boring show. It was based on a film that was written and directed by Frank D. Gilroy, called the ‘The Turning Point of Jim Malloy.’
The Brady Bunch Hour
This one-of-a-kind, 1976 TV show was not only short-lived, but it also made TV Guide's list as one of the five worst TV shows ever created...many times. 'The Brady Bunch Hour' was basically a show about the Brady family starring in their own TV variety show, which ended up being a complete flop.
Apart from a weak storyline, the show featured a lot of song-and-dance routines that made it feel like a cheap musical more so than a show. With only 9 episodes being filmed, 'The Brady Bunch Hour' barely lasted a few months and received awful reviews before ABC pulled it off the air altogether.
Bearcats!
CBS released 'Bearcats!' in 1971, in an attempt to get into the western TV show craze. The problem was that, by 1970, the interest in westerns had substantially gone down, and so the show was only on the air for thirteen episodes.
Its lead actors, Dennis Cole and Rod Taylor, played two adventurers riding around in a Stutz Bearcat in the American Southwest in 1914. CBS spent a lot of money on marketing the show, but it was all for nothing since, clearly, viewers weren't interested in a story set in 1914 anymore.
Karen
Premiering on ABC in January 1975, 'Karen' was a comedy series that followed the life of Karen Angelo, played by Karen Valentine. Angelo was a single, hard-working woman with a job at a Washington D.C.-based organization called 'Open America.' The organization sought to expose corrupt politicians and lobby for civil rights, and Angelo was at the forefront.
Unfortunately, an interesting premise and good acting weren't enough to keep the audiences' interest, so just six months after its release, ABC pulled the show off the air. A star-studded cast included Denver Pyle, Dene Dietrich, Oliver Clark, Aldine King, and more.
Co-Ed Fever
This CBS sitcom was such a disappointment that, out of the six episodes produced, only one ever aired. With a cast that included Alexa Kenin, Cathryn O’Neill, Heather Thomas, Tracy Phillips, and Jillian Kesner, 'Co-Ed Fever' followed the story of a group of young girls that lived in a dorm at Baxter College.
What's worse is that 'Co-Ed Fever' was meant to be one part of a three-part "frat house" comedy series, but the plot and production were so disastrous that all three of them were a flop.
