Why Sitcoms Still Use Laugh Tracks in 2026

In 2016, exactly three new broadcast sitcoms bothered with a laugh track, and all three aired on CBS. The format looked finished — a relic from an era of three-network television, kept alive by one aging demographic on one aging network. A decade later, broadcast television is currently running more multi-camera comedies with laughter than without: seven versus five. One of them, Chuck Lorre's "Georgie & Mandy's First Marriage," sits in the Nielsen top five.

The laugh track was supposed to be dead. Somehow it keeps getting back up.

Why do sitcoms still use laugh tracks?

Because, uncomfortably for its critics, it works on people. A 1974 study found that jokes followed by canned laughter increased what researchers called "conformity pressure" — test subjects rated the same joke funnier when they heard others laughing at it, essentially laughing along to fit in. More recent research described by The Hollywood Reporter found laugh tracks trigger something close to a mirror response, the same reflex that makes a yawn contagious. There's also a simpler explanation floating underneath the psychology: hearing other people laugh is warm. It turns a solitary act — one person, one screen — into something that feels shared, even at 1 a.m., even alone.

Where did the laugh track actually come from?

From a sound engineer's frustration with real audiences. Charles Douglass, an engineer at CBS, built a device in the early 1950s called the Laff Box that could play back a curated library of human laughter — hundreds of distinct laughs, according to Looper, most originally recorded during dialogue-free stretches of "The Red Skelton Show." Douglass built it because live studio audiences were unreliable — they laughed too long, too late, or not at all — and network executives wanted every joke to land the same way every time. The Laff Box debuted on 1950's "The Hank McCune Show" and by the following decades had become close to mandatory across American prime time.

It was never universally loved, even at its peak. A CBS production executive told Billboard magazine in 1955 that he personally hated "canned laugh tracks" but used them because television viewers expected an audience to be there. The actor and producer David Niven was less diplomatic, calling it, in a separate 1955 interview, "the single greatest affront to public intelligence I know of." None of that criticism slowed its spread. By the 1960s and '70s it had colonized even animated shows with no studio audience to sweeten in the first place — "The Flintstones," "The Jetsons," eventually the medical drama "M*A*S*H," whose co-creator Larry Gelbart fought for years to drop it and only won the argument for the show's operating-room scenes.

So why did it nearly disappear?

Two forces did the damage: international pushback and a new comedic style built to reject it. Several Latin American, Mexican and Canadian productions never adopted canned laughter at all, sometimes adding it only when a show was sold to a U.S. network. That example, paired with the rise of "cringe comedy" pioneered by the U.K.'s "The Office," gave American creatives room to argue the opposite case network executives had spent decades insisting on. "The Office," "30 Rock," "Arrested Development" and "Malcolm in the Middle" all built their humor on discomfort and silence rather than a cue to laugh, and audiences followed them anyway. By 2016, the laugh track had been reduced to three shows, all on one network, all seemingly waiting to be cancelled.

What changed to bring the laugh track back?

Television got relentlessly, aggressively real everywhere else, and the laugh track ended up looking strange again — strange enough to be interesting. Prestige comedies like FX's "The Bear" and prestige dramas like HBO's "The Last of Us" and "The Pitt" trade in grinding authenticity; a Disney "Star Wars" series is dark enough that critics compare it to a war drama. Against that backdrop, a multi-camera sitcom's shadowless living rooms and disembodied audience laughter read less like a dated format and more like a deliberate, almost theatrical artifice — a style choice rather than an accident of history.

Streaming comedies, by contrast, have mostly stayed single-camera, chasing the same grounded realism as prestige drama. That split has produced an odd generational gap: many of the highest-rated new streaming comedies still lose in the ratings to decades-old, laugh-tracked reruns of "Friends" and "The Big Bang Theory," shows a large chunk of their audience wasn't alive to watch the first time. It's the same tension that shows up in why streaming services keep cancelling shows after a single season — the economics of chasing prestige don't always match what audiences actually rewatch.

Does removing the laugh track change how a joke lands?

Often, yes, and not subtly. YouTube is full of "Friends" and "Big Bang Theory" clips with the laughter stripped out, and the effect is frequently described as unsettling rather than funny — one commenter, cited by Looper, said that without the laugh track, "it looks like a bunch of people who really hate each other." But the effect isn't universal. Researchers who compared audience response to laugh-tracked "Seinfeld" against the laugh-less, similarly aged "The Simpsons" found the two performed about the same, according to Science News — suggesting the track sweetens some material more than others, rather than functioning as a blanket trick that works on any joke.

There's also a stranger, more literal wrinkle to the format that has nothing to do with comedy theory. Many of the original Laff Box recordings, made in the 1950s, were still being recycled into shows decades after they were first captured — meaning a chunk of the laughter audiences hear on modern reruns came from people who are, by now, almost certainly dead. The joke lands. The laughter answering it is a ghost.
