Ratings decide a show’s fate fast, but they don’t always decide its legacy. Some series vanish from the schedule after a handful of episodes and still refuse to disappear.
The nine shows below each got a single season. Reruns, home video, streaming and word of mouth kept them alive long after the networks moved on.
Freaks and Geeks

Created by Paul Feig and executive produced by Judd Apatow, this NBC series followed high school students in suburban Michigan in 1980. It ran for 18 episodes across 1999 and 2000 before NBC canceled it. Its time slot kept shifting, which didn’t help it find an audience.
The cast later became a who’s who of comedy and drama, including Linda Cardellini, James Franco, Seth Rogen and Jason Segel. Fans kept discovering it through DVD sets and reruns. Its honest, awkward take on teenage life is still a regular reference point for later coming of age shows.
Firefly

Joss Whedon’s space western aired on Fox in 2002 and followed the crew of a small cargo ship on the fringes of a future society. Fox broadcast the episodes out of order, and only 11 of the 14 produced episodes aired on the network. The show was canceled before it could settle in.
DVD sales and passionate online fans kept it alive. That support helped bring about the 2005 feature film Serenity, which wrapped up several story threads. Nathan Fillion’s role as Captain Malcolm Reynolds is still one of his best known.
My So-Called Life

Winnie Holzman created this ABC drama, which aired in 1994 and 1995 and ran for 19 episodes. It centered on Angela Chase, a teenager played by Claire Danes, and treated her inner life with unusual seriousness. Critics loved it, though the ratings stayed modest.
After cancellation, repeat broadcasts on MTV introduced it to a new generation of viewers. Danes won a Golden Globe for her performance. The series is still often named among the most truthful portraits of adolescence on television.
Wonderfalls

Bryan Fuller and Todd Holland created this quirky Fox series, which debuted in 2004. Caroline Dhavernas played Jaye Tyler, a shop clerk at Niagara Falls who believes animal figurines are giving her cryptic instructions. Fox aired only four episodes before pulling it, even though 13 had been produced.
The unaired episodes eventually reached viewers on DVD. That release let fans see the complete story and helped the show grow a loyal base. Its mix of dark humor and fantasy still stands out from standard network comedy.
Terriers

FX aired this detective drama in 2010 for a single season of 13 episodes. Donal Logue and Michael Raymond-James played two small time private investigators working in Ocean Beach, San Diego. Reviews were strong, but viewership stayed low and the network didn’t renew it.
Critics have kept championing it as one of the best shows few people watched. Its relaxed, character driven approach set it apart from flashier crime series of the era. Streaming availability has since given it a second chance with new viewers.
Clone High

MTV aired Clone High in 2002 and 2003 for 13 episodes. The animated comedy imagined teenage clones of historical figures, including Abraham Lincoln and Joan of Arc, attending the same school. Phil Lord and Christopher Miller were among its creators, long before they became major film directors.
The show’s absurd humor found fans through reruns and online sharing. That lasting interest eventually led to a revival in 2023 on Max. Few canceled cartoons have returned after such a long gap.
The Tick

Fox aired a live action version of the comic character in 2001, starring Patrick Warburton as the oversized and cheerfully clueless hero. The series ran for nine episodes. Its deadpan parody of superhero conventions didn’t draw the numbers the network wanted.
Warburton’s performance became a lasting favorite among comedy fans. DVD releases helped the show reach viewers who missed it the first time. Later adaptations of the character followed, though this version is still the one many fans remember most fondly.
Undeclared

Judd Apatow created this Fox comedy about college freshmen, which aired in 2001 and 2002. It featured early roles for Seth Rogen and Jay Baruchel, along with a young cast that felt refreshingly natural. Fox canceled it after one season despite good reviews.
Like Freaks and Geeks before it, the show gained attention as its cast and creator became better known. Fans have long viewed it as a sibling series with a similar sense of humor. Its reputation grew steadily through DVD and later streaming.
Police Squad!

ABC aired Police Squad! in 1982, and just six episodes were produced. Created by David Zucker, Jim Abrahams and Jerry Zucker, it starred Leslie Nielsen as the deadpan Detective Frank Drebin. The show packed dense visual gags and wordplay into every scene.
Its cancellation didn’t end the character’s story. The same team turned the premise into The Naked Gun in 1988, and sequels followed. The original series is now remembered as the starting point of one of comedy’s most recognizable franchises.
