Before 'The Muppet Show,' Jim Henson produced slapstick coffee commercials featuring the puppets.

Jim Henson and his Muppets were part of the first season of 'Saturday Night Live' because NBC was hoping to tamp down Lorne Michaels' countercultural plans for the show.

'The Muppet Show' debuted in the UK because it was rejected by every US network.

Jim Henson and his creative team constructed several optical illusions to make the Muppets appear as though they walked through the real world.

Watch a medley of Pets.com commercials with the famous sock puppet mascot

Pets.com used a sock puppet decorated like a dog (operated by comedian Michael Ian Black) as the company's mascot. The sock puppet became synonymous with the brand. An auto lender company called BarNone Inc. later purchased the sock puppet for $125K and rebranded it with the slogan "Everybody deserves a second chance."

Jim Henson's lone Oscar nomination was for an experimental short film he made in the '60s that features no puppets.

Jim Henson's 1986 film 'Labyrinth' was initially a commercial failure in the US, though it slowly gained an audience that now considers it a cult classic.

Before 'SNL,' producer Lorne Michaels was a performer

Michaels was a costar on "The Hart and Lorne Terrific Hour," a popular show on the Canadian network CBC. As these clips show, it was a standard variety show, something Michaels would intentionally react against with "SNL."

Michael Nesmith, an original member of the '60s group the Monkees, created a music video show that inspired MTV.

'Potter Puppet Pals' was one of the internet’s first viral videos

Created by animator Neil Cicierega in the early 2000s, Potter Puppet Pals featured felt puppets parodying the Harry Potter characters. Its 2007 video “The Mysterious Ticking Noise” became an early YouTube sensation, amassing more than 200 million views.

Wally Feresten is the man behind the show's iconic cue cards

"SNL" obsessives are familiar with the show's cue cards, which occasionally appear on air in fourth-wall-breaking segments. They might even recognize Wally Feresten, the man who's been handwriting (and holding) them since 1990. This podcast interview delves into Feresten's curious life behind the scenes at "SNL" and his unexpected turns in front of the camera.

'SNL' began as a low-budget replacement for reruns of 'The Tonight Show'

Johnny Carson, host of "The Tonight Show," asked NBC to move his reruns to weeknights instead of weekends. That freed up a weekend slot and the network decided to try a new live show.

SNL's history in 60 seconds

Saturday Night Live has been a fixture of American comedy since 1975. Created by Lorne Michaels and Dick Ebersol, the show was designed as an alternative to late-night reruns, blending live sketch comedy, political satire, and celebrity impressions.

'Lazy Sunday' was YouTube's first viral hit

Initially aired on television, the 2005 "Saturday Night Live" digital short featuring Andy Samberg and Chris Parnell took off on YouTube, becoming one of the platform's first viral videos. The song may be a joke, but its success underscored how online video could extend the lifespan of regularly televised content.

'SNL' was originally called 'NBC's Saturday Night'

Another show already owned the title: the short-lived "Saturday Night Live with Howard Cosell." The variety show only lasted one season and was widely panned, despite featuring several talented comedians—like Bill Murray, Christopher Guest, and Billy Crystal—who'd later be stars on "SNL" ... after officially changing its name.

Watch the 'Star Wars Holiday Special,' a 1978 spin-off that became a cult classic

The CBS television special is a hokey variety show that was widely panned after it aired and, as a result, was never officially released on home video. George Lucas had little involvement, though it did feature the original cast alongside guest stars like Bea Arthur. Interestingly, it also features Boba Fett's first appearance.

Mel Brooks got his first big break in 1950 as a writer on Sid Caesar's 'Your Show of Shows,' a pioneering TV variety show.

Walt Disney’s Laugh-O-Gram Studio featured his earliest innovations in animation

From 1951 to 1965, the former B-24 bomber pilot performed science experiments that home audiences could replicate on "Watch Mr. Wizard," inspiring about 50,000 Mr. Wizard Science Clubs throughout North America. Subsequent series, including "Mr. Wizard’s World" and "Teacher to Teacher with Mr. Wizard," ran on Nickelodeon until 1996.

Following the scandals, CBS briefly banned canned laughter

The network was looking to correct the public perception that its programming was fraudulent, so it banned laugh tracks and fake applause from its broadcasts. The policy didn’t last long; within a few years, sitcoms were regularly “sweetened” with the sound effects.

Eddie Murphy saved ‘SNL’ from getting canceled in the early '80s

Before he had his own show, Pee-wee Herman appeared on 'The Dating Game'

Paul Reubens' character Pee-wee Herman would become a sensation with his 1986 children's show "Pee-wee's Playhouse," but in 1979 he appeared as the hilariously naive character on "the Dating Game." It's not clear if the show (or its audience) understood what they were seeing.

The ubiquitous 1990s “Got Milk?” ad campaign was intended to fix milk’s dwindling popularity in the late 20th century

Despite its success in spreading the word about milk, the sales numbers weren’t quite as impressive. This Mental Floss article details the marketing efforts themselves, as well as how milk lobbyists didn’t necessarily succeed despite their revolutionary ads.

'Truth or Consequences' was the first TV quiz show

The game—which forced contestants who answered questions incorrectly to face "consequences" in the form of wacky stunts—debuted in 1941 with a one-off experimental broadcast on WNBT, then reappeared on NBC in 1950. In 1956, a fresh-faced Bob Barker made his television debut as the show's new host.

After five seasons, Lorne Michaels quit ‘Saturday Night Live‘

Lorne Michaels left the show in 1980, citing burnout and disagreements with network executives. He tried several gigs, including a sketch comedy show called “The New Show” that was strikingly similar to “SNL,” but nothing stuck. He returned to "SNL" in 1985.

See a ranking of the most iconic Super Bowl advertisements ever aired

Mario's archnemesis hosted a children's show in the 1980s

"Super Mario Bros." grew so popular in the '80s, even King Koopa, the video game's villain, had his own television show, though it's been all but erased from TV history. There's good reason for that: It was a bizarre enterprise, featuring '30s cartoons, a grumpy stand-up comedian, and cheap production.

'SNL' spinoffs have had mixed success

As “SNL” became more popular, Lorne Michaels sensed an opportunity to turn some of the show’s most popular sketches and characters into feature films. It’s a strategy that had mixed results: “Wayne’s World” and “The Blues Brothers” are modern classics, while others, like “It’s Pat” and “The Ladies Man,” performed poorly with audiences and critics alike.

Comedian Nathan Fielder opened a store called 'Dumb Starbucks,' which was protected by US parody law.

Jim Downey arrived at “Saturday Night Live” in 1976, the same week as Bill Murray. He also wrote a legendary monologue from “Billy Madison,” and created David Letterman’s “Top Ten."

John Pemberton only sold roughly 25 gallons of Coca-Cola syrup in its first year

That equates to roughly 9 drinks per day. But once he brought it to pharmacies that hooked the syrup up to their soda fountains, sales increased significantly, with roughly 2,000 gallons being sold two years later. This video about Coca-Cola's early history is narrated by actress Jenny Slate for a Comedy Central series called "Drunk History," so not all of it is intended to be entirely factually accurate.

Matt Groening wrote the comic 'Life in Hell' before creating 'The Simpsons'

The strip began in 1977 as a self-published book featuring disturbing-looking rabbits navigating the indignities of life in Los Angeles, where Groening had recently moved. It was picked up by the Los Angeles Reader in 1980 and then syndicated by over 250 newspapers by 1986. Eventually, it caught the eye of James L Brooks, who was looking for a cartoonist to create sketches for "The Tracey Ullman Show" for Fox.
