Old TV shows are what made TV shows what they are TV. They are the blueprint for what to do (in terms of writing) or what not to do (like that Seinfeld series finale). Here are some of the top older TV shows that are available on streaming services such as Netflix, Hulu and Prime Video.

Note that this list will be TV shows that started before the beginning of the 21st Century.

MASH (Hulu): Seasons 1-11

Cheers (Hulu): Seasons 1-11

Friends (Netflix): Seasons 1-10

Seinfeld (Hulu): Seasons 1-9

Home Improvement (Hulu): Seasons 1-9

Classic Doctor Who (Britbox): Seasons 1-26

Roseanne (Pluto TV): Seasons 1-9

Third Rock from the Sun (Pluto TV): Seasons 1-6

The Brady Bunch (Hulu): Seasons 1-5

Married with Children (Hulu): Seasons 1-11

The Waltons (Prime Video): Seasons 1-9

Obviously, this is not all of the great shows of the 20th century, but they are shows that did make people happy during that century. Since we are in the new spring season, this could be a great time to get your spring binge-watching on.

All of the services mentioned here are available on the iPhone, iPod Touch, iPad, Apple TV and Mac.
