Film and television animation is still a hugely popular medium, but it was in the 1960s that Saturday morning cartoon blocks first appeared. Few things were sweeter for youngsters in the late-20th-Century than waking up bright and early on weekend mornings and consuming a big bountiful bowl of breakfast cereal while lounging in front of the television still in your jammies. Children were entertained by television with programs about criminal fighters, talking animals, small blue creatures, and other animated phenomena.

Update July 10, 2023: This article has been updated to include even more nostalgic Saturday morning cartoons.

Every Saturday morning, from approximately eight until noon, when school wasn't a problem, and it was time to unwind, each generation had its own favorite cartoons that they had to watch. Entertainment enthusiasts would argue that today's youngsters are overlooking one of the mainstays of growing up, but the truth is: kids no longer have to wake up in the early morning hours to view a certain block of programming once every week. Because of rules enacted on children’s programming (as outlined by Variety) requiring educational content, the growth of technology, the creation and abundance of video games, and the dominance of streaming services, Saturday morning cartoons are now a thing of the past. Put on your pajamas, get a big bowl of cereal, and start watching these Saturday morning cartoons that will make you nostalgic for your younger years.

20 Tom and Jerry Kids

This is a favorite rendition of the well-known cat and mouse cartoon, though there are many more out there. It was filled with imaginative chases and silly cartoon violence. Tom and Jerry Kids is superior to the Tom and Jerry Show from 1975, in which the natural enemies were bafflingly made to be friends, or the awkward animation of The Tom and Jerry Comedy Show from the early-080s. It's simply Tom the Cat and Jerry the Mouse showing the youngsters how absurd conflict is. Tom and Jerry Kids aired on Fox from 1990 to 1994.

19 The Bugs Bunny Show

Almost everyone at some point has seen The Bugs Bunny Show characters from this iconic program. The Bugs Bunny Show began in primetime but relocated to Saturday mornings after only two seasons, where it continued in various guises for almost four decades. Numerous animators and storytellers were inspired by the cartoons, and even now, many years later, people still like watching the episodes. The Bugs Bunny Show aired on CBS from 1968 to 2000.

18 Teenage Mutant Ninja Turtles

Teenage Mutant Ninja Turtles would be the ideal franchise to create if you were looking to appeal to dudes of all ages. The four skateboarding turtles are literally living in a sewer with their bearded rat sensei, who is feeding them as much pizza as they can handle. Yes, after the turtles invaded the world of merchandise (school bags and cuddly toys), it became a touch overdone, but there was a time when Saturday mornings wouldn't have been worth it without the reptiles with their charming names. Teenage Mutant Ninja Turtles aired on CBS from 1987 to 1996.

17 Voltron: Defender of the Universe

Voltron: Defender of the Universe was one of those Saturday morning cartoon programs that wasn't the greatest. It was successful because of its toy line, which contained awesome action figures of the characters. The Japanese anime television series Beast King GoLion served as the inspiration for the first season's Lion Force Voltron, while the unrelated Japanese anime television series Armored Fleet Dairugger XV served as the inspiration for the second season's Vehicle Voltron.

The U.S. version of the program centered on a group of five young pilots who were in charge of five robot lions that, when assembled, became Voltron, a massive robot fighter. Voltron: Defender of the Universe was in syndication from 1984 to 1985.

16 Inspector Gadget

Chronicling the countless misadventures of the dim-witted but well-meaning eponymous crime fighter and cyborg human, Inspector Gadget was a fun and massively entertaining show for kids that showcased the police inspector's many awe-inspiring devices that help him solve cases and fend off his dangerous arch nemesis Dr. Claw. The superhero sci-fi comedy series ran from 1983 to 1986 but remained in syndication well into the late '90s, attracting a new audience of passionate viewers that became enamored by the delightfully bumbling protagonist. The program's success led to the establishment of the Inspector Gadget franchise that would lead to countless films, TV shows, and video games.

15 DuckTales

The experiences of Scrooge McDuck and his three grandnephews, Huey, Dewey, and Louie, who were left with Scrooge after their Uncle Donald Duck enlisted in the Navy, were chronicled in the Disney animated series Duck Tales. McDuck's money or his lucky dime would be sought for by evil villains in the episodes. Everyone also adored Scrooge McDuck's money box, which was so full of gold coins that he could jump in and swim through it almost like a huge pool.

Duck Tales, which ran from 1987 to 1990, was rerun on ABC from 1996 to 1999. The 1990 animated feature film DuckTales the Movie: Treasure of the Lost Lamp and a 2017 television series relaunch with David Tennant as Scrooge's voice were both inspired by the series.

14 Darkwing Duck

Following the conclusion of Ducktales, the Darkwing Duck narrative was developed into a stand-alone series. The cartoon followed an anthropomorphic duck character who must combine his desire for glory as the mask-wearing superhero Darkwing Duck with his attempts to be a loving-urbanized parent to his adoptive daughter Gosalyn. Darkwing Duck originally aired on Disney Channel in 1991, got syndication, and moved to ABC, where it aired from 1991 to 1992.

13 Sonic the Hedgehog

Oddly enough, in the early-90s, two distinct cartoons with a Sonic theme were broadcast simultaneously: The Adventures of Sonic the Hedgehog and Sonic the Hedgehog. Our hearts belong to Sonic the Hedgehog, lovingly dubbed Sonic SatAM, because it aired on Saturday mornings and maintained a darker atmosphere in contrast to the well-known video games. Even if it immediately qualifies as a classic since Steve Urkel (Jaleel White) provided the voice for Sonic, the point is further emphasized by the excellent visuals and unexpectedly good character-building. From 1993 to 1994, Sonic the Hedgehog was broadcast on ABC.

12 He-Man and Masters of the Universe

The toy line Masters of the Universe by Mattel served as the inspiration for He-Man and the Masters of the Universe. The show is set on the magical, mythical, and fantastical planet of Eternia. The most powerful man in the universe, He-Man, is created whenever Prince Adam raises the Sword of Power and declares, "By the Power of Grayskull!" he is given amazing secret powers. He-Man and She-Ra: The Secret of the Sword is the feature-length theatrical film that served as the premiere for the show's spinoff series She-Ra: Princess of Power. The initial run of He-man and the Masters of the Universe ran in syndication from 1983 to 1985. Reruns remained in syndication until 1988, when the USA network bought the rights and broadcast the series from 1988 to 1990.

11 ThunderCats

One of the most interesting Saturday morning offerings was ThunderCats. The titular characters of the Rankin-Bass children's classic animated series, Lion-O, Cheetara, Panthro, Tygra, WilyKit, and WilyKat, followed a gang of cat-like humanoid aliens on the planet Third Earth. In essence, ThunderCats fulfilled the long-standing childhood ideal of playing the part of a giant cat, which the program effectively catered to. ThunderCats spawned two reboots that continued the original storyline. From 1997 through 2002, Cartoon Network aired a rerun of Thundercats, which first ran in syndication from 1985 to 1989.

10 The Smurfs

No matter what you may think of the latest hybrid Smurfs films — which are being delayed, per DeadlineThe Smurfs is a must-see. In the 80s, the Saturday morning cartoon block featured a lot of episodes of the Hanna-Barbera Productions television series. Based on a Belgian comic called Les Schtroumpfs by artist Peyo, the animated series follows a group of little blue creatures that hide in the woodland in mushroom-shaped homes from the evil wizard Gargamel and his cat Azrael, who seek to kidnap the Smurfs, so they may make a potion that would convert ordinary stuff into gold. NBC broadcast The Smurfs from 1981 until 1989.

9 Animaniacs

The WB

After a long first season, Animaniacs, which debuted as an afternoon weekday program, switched to Saturday mornings. It included a big cast divided into various segments. The Warners, three brothers known as Yakko, Wakko, and Dot, were prominently displayed. These 1930s cartoon characters were imprisoned in the Warner Bros. water tower on the Burbank studio property until the 90s when they managed to escape. Pinky and the Brain, two genetically modified laboratory mice that repeatedly and vainly try to rule the world, were the subject of another well-liked recurring section. From 1993 to 1995, Animaniacs aired on Fox; from 1995 to 1999, it moved to The WB.

8 Pinky and The Brain

A spin-off to the wonderfully zany WB series Animaniacs, the '90s sci-fi comedy hit Pinky and The Brain follows the mismatched pair of genetically modified lab mice as the diabolical Brain and dopey Pinky attempt to gain complete power and plot to take over the world. The underrated cartoon gem ran from 1995 to 1998 for four seasons on the Kids' WB, and like with its companion show, much of the humor was directed at adult audiences, and it was full of hilarious parodies of major pop culture moments and figures. The entertaining characters from Pinky and the Brain went on to return as a segment in the 2020 revival of Animaniacs, airing for three seasons.

7 X-Men: The Animated Series

The wholesome and fun program concluded in 2001 but due to its immense popularity with young audiences, the series yielded the theatrical film Recess: School's Out that same year and an additional three direct-to-video sequels.

4 Scooby-Doo, Where Are You!

Taft Broadcasting 

One of the most enduring symbols of children's television is Scooby-Doo, Where Are You!. Four youngsters (Fred, Daphne, Velma, and Shaggy) and a cowardly dog named Scooby-Doo were followed on television in the Hanna-Barbera series as they drove in the Mystery Machine van, which would frequently conveniently break down or make a pit stop at an odd perhaps haunted place. The members of Mystery Inc. offered their assistance in order to try to solve the weekly spooky mystery.

The series went on to inspire movies, more television shows, children’s toys, merchandise, and more. Scooby-Doo even had a crossover with the live-action paranormal hunting series, Supernatural. Surprisingly enough, Scooby-Doo, Where Are You! aired on CBS for only a short time, from 1969-1970.

3 Tiny Toon Adventures

Pig. Classic Warner Bros. characters like Bugs Bunny, Elmer Fudd, and Daffy Duck pop up in the series as the college's faculty members, and it heavily parodies Hollywood and major events from the 1990s via the use of slapstick humor and cartoon violence. Tiny Toon Adventures ran from 1990 to 1992 for 3 seasons and also had two specials that were released in 1994, and it is getting rebooted with Tiny Toons Looniversity, scheduled to debut in September 2023.

1 Pokémon

For late 90s and early 2000's kids, Pokémon was THE cartoon of the era. Based on the popular video game, the story of Ash Ketchum and Pikachu on a quest to become a Pokémon master entertained kids all over the world. It helped solidify Kids WB as a Saturday Morning destination that later shows like Yu-Gi-Oh, Jackie Chan Adventures, and Xialon Showdown would cash in on. While Pokémon never quite went away, and Ash's story only just recently concluded, those early years of the anime series hold a special place in the hearts and minds of fans. Just play that incredible theme song and watch an entire room start to sing along.
