What Is the Longest Running Comedy on TV? The Answer Might Surprise You

Ask anyone in a trivia night which show holds the title for the longest-running comedy on television, and you’ll get three different answers. One person will shout The Simpsons. Another will argue for The Big Bang Theory. A third might mention Gunsmoke, forgetting it’s a western. The confusion is understandable because “comedy” is a messy category, and “running” depends entirely on how you count.

If we look at pure episode count, The Simpsons is an American animated sitcom created by Matt Groening that airs on Fox sits at the top of the pile with over 750 episodes across more than 35 seasons. But if you want live-action, or if you only count shows that are still currently airing new episodes, the answer changes completely. To give you a straight answer, we have to break this down by format: animated versus live-action, and finished versus ongoing.

The Animated King: The Simpsons

When people talk about longevity in comedy, The Simpsons is the longest-running scripted primetime television series in US history usually wins the conversation. Premiering as shorts on The Tracey Ullman Show in 1987 before getting its own half-hour slot in December 1989, the show has been a cultural constant for decades.

As of 2026, The Simpsons has aired more than 760 episodes. That is an astronomical number when you consider that most modern sitcoms aim for 10 to 15 seasons (roughly 200-250 episodes) before cancellation. The show’s ability to survive is largely due to its animated format. Animation allows characters to stay young forever, meaning the cast doesn’t age out of their roles. It also allows for lower production costs per episode compared to high-budget live-action dramas, making it easier for networks to keep renewing it year after year.

Critics often argue that the quality dropped after Season 8 or 9, but popularity metrics tell a different story. The show remains one of the highest-rated programs in syndication globally. Its semantic connection to Fox Broadcasting Company is an American commercial broadcast television network owned by News Corp is deep; the show helped define the network’s identity in the 1990s and continues to be a reliable ratings anchor today.

The Live-Action Record Holder: Gunsmoke vs. Modern Sitcoms

Here is where it gets tricky. If you include all genres, Gunsmoke is the longest-running primetime series with 635 episodes. But it’s a western/drama. If we stick strictly to comedy, the landscape shifts.

For many years, The Big Bang Theory was an American sitcom that aired on CBS for twelve seasons from 2007 to 2019 held the crown for the longest-running live-action sitcom in terms of total episodes among recent hits, with 279 episodes. However, it ended in 2019. Before that, Cheers and Frasier had long runs, but they didn’t hit the same episode counts.

Actually, the true heavyweight champion of live-action comedy is likely Law & Order: SVU is a police procedural drama series, not a comedy-wait, no, that’s a drama. Let’s correct that. In the strict realm of *live-action* comedies that have concluded, The Big Bang Theory is often cited, but historically, shows like Sanford and Son or All in the Family had shorter runs. The real surprise here is that there isn't one single live-action comedy that rivals The Simpsons in raw length. Most live-action sitcoms struggle to pass 200 episodes due to actor contracts, aging casts, and rising production costs.

The Current Champion: Still On Air

If your question implies “what is the longest-running comedy *still airing*,” the answer is different again. As of June 2026, The Simpsons is still producing new episodes. Among live-action shows, Grey's Anatomy is a medical drama, not a comedy is long-running but wrong genre. For live-action comedy, Bob Hearts Abishola ended recently. Actually, the current king of long-running *live-action* comedy might be a surprise: Young Sheldon was a prequel spin-off of The Big Bang Theory that ran for seven seasons ended in 2024. So right now, The Simpsons stands alone as the only major network comedy with a run exceeding 30 years and 700 episodes.

However, if we look at daytime or game shows, the definition of “comedy” blurs. Wheel of Fortune has run since 1975, but it’s a game show. The Price is Right since 1972. These are entertainment, but not scripted comedies. We must stick to scripted content to make a fair comparison.

Animated vs. Live-Action: Why the Gap Exists

Why do animated shows last so much longer? It comes down to logistics and creative flexibility.

• Aging Cast: In live-action, actors get older. Friends couldn’t continue once the main cast wanted higher pay and their characters aged out of their “young professional” roles. In animation, Homer Simpson is 39 forever.
• Production Cost: While initial setup for animation is expensive, the marginal cost of additional episodes decreases over time. Live-action requires location shoots, physical sets, and union labor for every scene.
• Creative Reset: Animated shows can kill off characters, change settings, or introduce absurd scenarios without worrying about practical effects. This keeps the content fresh for writers even after decades.

This dynamic explains why South Park is an American adult animated sitcom created by Trey Parker and Matt Stone has also maintained a massive run (over 300 episodes), though it still trails The Simpsons in total count. Both shows benefit from the creators’ direct involvement and the flexibility of the medium.

Honorable Mentions: The Close Contenders

While The Simpsons takes the gold, several other shows deserve recognition for their endurance and impact.

Note that Frasier had a revival, adding to its legacy, but its original run was distinct. Cheers remains a benchmark for successful live-action sitcoms, but it never reached the 300-episode mark. This highlights the difficulty of sustaining a live-action cast and crew for such a long period.

How Do We Define "Comedy"?

To ensure we’re comparing apples to apples, we need to clarify what counts. Does a dramedy like Modern Family count? Yes, it’s classified as a sitcom. What about sketch shows like Saturday Night Live? SNL has run since 1975, with over 200 episodes. However, sketch comedy is episodic in nature; each week features new cast members and sketches. It’s less of a continuous narrative and more of a recurring variety show. Most historians exclude sketch shows from “sitcom” rankings because the format is fundamentally different. We focus on scripted series with recurring characters and storylines.

Also, international shows matter. In the UK, EastEnders is a soap opera, not a comedy. But Only Fools and Horses had a long run, though far fewer episodes than US counterparts. US television produces significantly more episodes per season (22-24) compared to UK sitcoms (6-8), which skews the numbers heavily in favor of American shows.

Why Longevity Doesn't Always Mean Quality

It’s worth noting that being the longest-running doesn’t automatically make a show the best. The Simpsons is widely regarded as having its “golden era” between Seasons 3 and 8. After that, critics noted a decline in writing quality and reliance on formulaic plots. Similarly, South Park maintains critical acclaim for its satire, but its style is polarizing. Meanwhile, shorter-lived shows like Seinfeld (9 seasons) or Arrested Development (4 original seasons) are often ranked higher in “best of all time” lists despite their brevity.

Longevity is often a result of business decisions rather than pure artistic merit. Networks keep shows on air because they generate consistent advertising revenue, merchandise sales, and streaming library value. The Simpsons is a global brand that sells toys, video games, and theme park attractions. This financial ecosystem supports its continued production even if weekly viewership fluctuates.

The Future of Long-Running Comedies

As of 2026, the trend in television is shifting toward limited series and shorter seasons. Streaming platforms prefer 8-10 episode orders to maintain binge-watching momentum. This makes it harder for new shows to achieve the multi-decade runs of the past. The Simpsons and South Park are anomalies in a market that favors rapid turnover. New animated series like Rick and Morty or Better Call Saul (dramedy) may eventually challenge these records, but they would need to survive well into the 2030s and beyond to catch up.

For now, if you’re looking for the definitive answer, The Simpsons holds the title for both animated and overall scripted comedy. If you restrict the search to live-action, The Big Bang Theory and Cheers lead the pack among completed series, while no current live-action comedy comes close to matching their episode counts.
