Growing up with a TV in the 90s or early 2000s meant one thing. You were basically a test subject for some of the weirdest, most experimental animation ever put to screen. Honestly, looking back at cartoon network shows all the way from the "Checkerboard" era to the present day, it's a miracle half of this stuff got greenlit. While Disney was busy being polished and Nickelodeon was focused on being "gross-out" funny, Cartoon Network was the place for the outsiders.
It wasn't just about the cartoons. It was about an attitude.
The network started as a way for Ted Turner to dump old Hanna-Barbera reruns into a 24-hour cycle. Nobody thought it would become a cultural powerhouse. But then the "What a Cartoon!" project happened. Suddenly, you had creators like Genndy Tartakovsky and Craig McCracken just doing... whatever they wanted. That’s how we got the classics. But the history of these shows is a lot messier than the nostalgia-tinted TikTok edits make it look.
The Experimental DNA of the Classics
If you look at cartoon network shows all together, the early 2000s were the undisputed peak of creative freedom. Dexter’s Laboratory and The Powerpuff Girls were the hits, sure. But think about Courage the Cowardly Dog. That show was legitimately terrifying. It used photo-realistic masks, 3D CGI models that didn't fit the art style, and psychological horror themes that probably sent a few kids to therapy. John R. Dilworth, the creator, basically treated a kids' network like an indie film festival.
It worked because the network didn't have a "brand" yet. They were desperate for content.
Then came the "City" era. This was arguably the best branding in TV history. They made it look like all the characters lived in one giant metropolis. You’d see the Joker getting a parking ticket while the Eds from Ed, Edd n Eddy were trying to scam him in the background. It created this sense of a shared universe long before Marvel made it cool. It made the viewers feel like they were part of a club.

Ed, Edd n Eddy is a weird one to revisit. Danny Antonucci, the creator, was known for adult animation like Lupo the Butcher. He brought this frantic, wobbling line art to a show about three kids trying to buy jawbreakers. It ran for nearly a decade. Why? Because it felt real. It captured the boredom of summer vacation better than any live-action show ever could.
When Things Got Weird: The Advent of Adult Swim and Late-Night Shifts
You can't talk about the full roster of shows without mentioning the split. In 2001, Adult Swim launched. It changed everything. Suddenly, the "all" in cartoon network shows all day long became a divided house. Space Ghost, a forgotten Hanna-Barbera superhero, was repurposed into a talk show host who hated his guests. It was anti-humor before the internet invented the term.
This era proved that animation wasn't just for kids. Samurai Jack is the perfect example. It’s a show that relies on silence. Genndy Tartakovsky used cinematic letterboxing and long, sweeping shots of landscapes inspired by Akira Kurosawa films. There are episodes where almost no one speaks for ten minutes. For a kids' network, that’s a death sentence in terms of "attention spans," yet it became one of the most respected pieces of animation in history.
But the mid-2000s were a bit of a slump. Remember the "CN Real" era? Most people try to forget it. The network tried to pivot to live-action reality shows like Destroy Build Destroy. It almost killed the brand. Fans hated it. The soul was gone.
The Renaissance: Adventure Time and the New Wave
Around 2010, everything changed again. Adventure Time and Regular Show arrived. If the early era was about "funny," this era was about "lore."

Pendleton Ward’s Adventure Time started as a goofy short about a boy and a dog. It ended as a sprawling epic about a post-apocalyptic wasteland, the cycle of reincarnation, and the trauma of a thousand-year-old ice wizard. It paved the way for Steven Universe, which tackled identity and grief in ways that were frankly revolutionary for a "cartoon." Rebecca Sugar, who worked on Adventure Time before creating Steven Universe, brought a musicality and emotional depth that hadn't been seen since the Disney Renaissance films.
Here's the thing people get wrong: they think these shows were just "random." They weren't. They were incredibly structured. The Amazing World of Gumball is a technical nightmare. It mixes 2D, 3D, stop-motion, and live-action backgrounds in every single frame. It’s one of the most expensive-looking shows ever made for TV, yet it plays it off like a low-budget sitcom.
The Shows That Time Forgot
We always talk about Johnny Bravo or Ben 10. But what about the ones that slipped through the cracks?
- Sheep in the Big City: A pun-heavy, surrealist masterpiece that felt more like a New Yorker comic than a cartoon.
- Time Squad: A show about fixing history that actually taught you things, albeit in a very chaotic way.
- Megas XLR: A love letter to anime and car culture that was canceled way too soon due to tax write-off nonsense.
- Sym-Bionic Titan: Another Tartakovsky gem that got axed because they couldn't figure out how to make toys for it.
The toy thing is a recurring theme. A lot of great cartoon network shows all suffered because they didn't sell plastic figurines. Young Justice was famously canceled (the first time) because the audience was "too female," and apparently, the executives thought girls didn't buy action figures. It’s a cynical side of the industry that often kills the best art.
The Impact of Streaming and the Future
Today, the landscape is fractured. Max (formerly HBO Max) is where a lot of these shows live now. The "Checkered Past" block on Adult Swim is trying to bring back that old feeling by airing Dexter and Courage for nostalgic millennials. It’s a smart move. People are tired of the ultra-clean, "CalArts style" animation that has dominated the last few years. They want the grit. They want the weirdness.

Look at Primal. It’s a show with zero dialogue about a caveman and a dinosaur. It’s brutal, beautiful, and airing on a network that started with The Flintstones. That’s a wild trajectory.
The reality is that Cartoon Network has always been at its best when the executives stay out of the way. When they let creators like Mike Lazzo or C.H. Greenblatt (Chowder) just do their thing, we get classics. When they try to chase trends (like the "CN Real" debacle or the excessive Teen Titans Go! marathons), the quality dips.
How to Revisit the Catalog Like an Expert
If you're looking to dive back into cartoon network shows all at once, don't just watch the hits. You’ve seen The Flintstones. You’ve seen Scooby-Doo. To really understand what made this network special, you have to look at the transition points.
- Watch the Pilots: Check out the original What a Cartoon! shorts. You can see the raw, unpolished versions of Family Guy, Johnny Bravo, and Larry & Steve (which eventually became Family Guy). It’s a masterclass in seeing how a character is born.
- Follow the Creators: If you like Dexter’s Lab, watch Samurai Jack and then Primal. You can see Genndy Tartakovsky’s style evolve from "thick outlines and comedy" to "no outlines and pure action."
- Appreciate the Soundscapes: Shows like Chowder and The Marvelous Misadventures of Flapjack used incredible sound design and mixed media. They don't look like anything else on TV.
- Check the "Canceled Too Soon" List: Watch The Life and Times of Juniper Lee or Generator Rex. These shows had massive potential but were overshadowed by the giants of their era.
The history of animation is basically the history of Cartoon Network. It’s the story of a weird little cable channel that decided kids deserved better than 22-minute toy commercials. They deserved art. Even if that art was a cow and a chicken being siblings, or a boy with a watch that turned him into aliens. It was all experimental. It was all a bit risky. And that's exactly why we still care about it twenty or thirty years later.
If you want to stay updated on where these shows are streaming or which ones are getting reboots (like the upcoming Powerpuff Girls revival), keep an eye on industry trade publications like Variety or Animation Magazine. The corporate shuffles at Warner Bros. Discovery mean the "all" in cartoon network shows all is constantly moving between platforms. Don't rely on just one streaming service; sometimes the best stuff is tucked away in "Legacy" sections or digital purchase stores. Your best bet is to build a physical collection of the "holy trinity" eras—the 90s classics, the City era, and the 2010s Renaissance—before licensing deals make them vanish into the digital ether.
