The 70s weren't the greatest time for TV shows, considering that 45 out of 96 shows got canceled.
That being said, 1978, which was, believe it or not, 40 years ago, aired a handful of memorable shows that are still talked about today.
Here are 10 beloved TV series that are turning 40 years old in 2018.
1. Battlestar Galactica
After the success of Star Wars, space operas became the latest Hollywood craze in the late 70s and early 80s. Surprisingly, the show ran for a year until it was canceled in 1979, but a campaign revived the show as Galactica 1980.
2. WKRP in Cincinnati
The lives of people working at a struggling radio station was a late 70s favorite, and its success lasted for a decade. The sitcom won a Humanitas Prize and was nominated for many Emmy Awards.
The mystery of "Who shot J.R.?" had people from around the world hooked. This soap opera series was loved so much that it was aired in countries behind the Iron Curtain. One of the episodes from 1980 is still the highest-rated prime-time telecast ever.
4. Mork & Mindy
In 1978, Hollywood's most beloved actor, Robin Williams, rose to stardom on the sitcom Mork & Mindy. Williams hilariously portrayed the character of an extraterrestrial, and the romantic love story between him and Mindy was just heart warming.
5. Diff'rent Strokes
Diff'rent Strokes set the bar high when it first aired in 1978. Gary Coleman and Todd Bridges played two African American boys from Harlem who are taken in by an affluent white family. The show was so popular that it started the catchphrase "What'chu talkin' 'bout, Willis?"
