Most of the ‘Super Mario Bros.’ sequel was borrowed from a preexisting Nintendo game

‘Mario Bros.’ was a 'Donkey Kong' spin-off

“Donkey Kong” was a big success, spawning a sequel and a Mario spinoff: 1983’s “Mario Bros.,” starring Mario and his brother Luigi. Realizing his hero didn’t resemble a classic carpenter, Miyamoto turned Mario into a plumber and set the brothers loose in a sewer system that resembled the platform-climbing gameplay of “Donkey Kong.” Watch the gameplay below.

‘Super Mario Bros.’ was influenced by ‘Alice in Wonderland’

In 1985’s “Super Mario Bros.,” Mario and Luigi grow larger—becoming “Super Mario Bros.”—if they ingested mushrooms. “...if you think of stories like ‘Alice in Wonderland’ and other types of fairy tales, mushrooms always seem to have a mysterious power, and so we thought the mushroom would be a good symbol for why they get it and get big,” Miyamoto told NPR in 2015.

The levels for 'Super Mario Bros.' were designed by hand

Miyamoto and codesigner Takashi Tezuka sketched the world of the game—called Mushroom Kingdom—by hand before handing it off to developers. In the interview below, they show off some of those original illustrations.

'Super Mario Bros.' was released in 1985

The game was designed by Shigeru Miyamoto and Takashi Tezuka and published by Nintendo in Japan and North America in 1985. It’s seen as a landmark in the history of video games and minted the Mario character as a pop culture icon.

'Super Mario Bros.' teaches players its rules as they go

Rather than constantly climbing up the screen from platform to platform like “Donkey Kong,” “Super Mario Bros.” moves from left to right. In anticipation of gamers’ confusion with the new style, Miyamoto designed the first level as a walk-through, allowing players to learn the rules without reading a manual.

'Super Mario Bros.' helped save the video game industry

A 1983 crash left the industry in tatters, desperate for a hit. Nintendo’s focus on a more immersive home experience was realized in “Super Mario Bros.,” bringing the industry from the arcade to the living room. The title eventually sold over 40 million units.

The game turned Japan into a major cultural exporter

“Super Mario Bros.” kicked off decades of cultural ascendancy not only for Nintendo, but for Japan, which grew into one of the world’s major cultural exporters through anime, fashion, and music.

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.

1993’s ‘Super Mario Bros.' was the first live-action movie based on a video game

The 1993 live-action adaptation was supposed to be an easy hit, thanks to the brand Nintendo had already established. But the film, starring Bob Hoskins, John Leguizamo, and Dennis Hopper was a critical and commercial flop. Hoskins would later called it “the worst thing I ever did.”

Famicom was the predecessor to the NES

Before the Nintendo Entertainment System was released in the US, Nintendo released a similar console in Japan with some interesting differences, including a Delorean-like exterior and a built-in microphone for karaoke.

Koji Kondo composed the game’s iconic soundtrack with a limited palette of sounds

The game’s soundtrack and effects were limited by the Nintendo Entertainment System’s 8-bit hardware, which had significantly fewer sounds than a typical synthesizer. That didn’t stop Kondo from writing some of the most recognizable video game music in history.

The origins and evolution of the movie sequel

Sequels have long leveraged the financial success of a first installment into a second, or third, part, as far back as the earliest novels in the 18th century, like Jonathan Swift's "Gulliver's Travels," which inspired countless spin-offs. The film...

'Stadium Events' is one of the rarest Nintendo games

The game, in which players compete in Olympic-style events, is notoriously boring, but it's also incredibly rare, thanks to a branding change after the cartridge's initial run. That's made it one of the most sought-after video games, with buyers paying over $35K for it.

Sudoku was originally called 'Number Place'

While there are earlier variations on the game, the modern version appeared in 1979, though it was then called "Number Place." The game was slightly altered and renamed in Japan.

The 1987 Nintendo video game 'Stadium Events' isn't known for being particularly fun, but its scarcity has made it a highly sought-after item that has sold for up to $35K at auction.

The game 'Counter-Strike' was developed in a dorm room

College student Minh Le designed the game through "modding," effectively building on the code of a preexisting game, the game "Half-Life" in his spare time.

'Romeo and Juliet' was based on a preexisting narrative poem

Arthur Brooke's "The Tragical History of Romeus and Juliet" was first published in 1562 and shares many details with Shakespeare's "Romeo and Juliet." Shakespeare wasn't alone in his borrowing; Brooke's poem was based on other earlier Italian stories. None of this writing was considered fan fiction—copyright law didn't exist, and stories were regularly cribbed from preexisting sources.

'The Simpsons' show-within-a-show was based on a real cartoon

Most "Simpsons" fans assume "The Itchy and Scratchy Show," the violent cartoon Bart Simpson loves, is a disturbing inversion of "Tom and Jerry." In reality, it's based on "Herman and Katnip," a "Tom and Jerry" knockoff that was similarly grotesque.

'The Empire Strikes Back' was influenced by 'Apocalypse Now,' a movie George Lucas was originally supposed to direct

Lucas provided the name for the gritty movie about the Vietnam War (and was supposed to direct it before it was taken on by his friend, Francis Ford Coppola), but the 1980 installment in the "Star Wars" saga features several parallels to "Apocalypse Now," including the dark, mysterious setting and aerial fight scenes.

Components of the 'ghost gun' allegedly used by Luigi Mangione were 3D printed

Although some "ghost guns" are firearms whose serial numbers have been removed, many others are built from pieces that can be printed using readily available online data files. Federal laws and some states do not prohibit the construction of these DIY firearms for personal use.

Parents criticized 'Dungeons & Dragons' during the 'Satanic Panic'

The role-playing game became popular enough to attract the ire of special interest groups, like Bothered About Dungeons & Dragons (or BADD) during the so-called "Satanic Panic" of the 1980s and 1990s, when parents believed the game was corrupting children.

The Ramones' 'Pet Sematary,' the theme song for the Stephen King novel of the same name, was written while the band was admiring the writer's collection of horror memorabilia.

Some Pokémon have been named after real and fictional organisms, while some real-world species have been named after Pokémon, such as Chilicola charizard and Binburrum zapdos.

Stephen King's basement inspired a Ramones classic

The horror writer was a fan of the band and invited them to his home in Maine. While hanging out in the basement, Dee Dee Ramone, the band's bassist, stole away with a copy of King's "Pet Sematary" and wrote a song about it. The song appeared in the film adaptation of the book, which began shooting a month later.

2 Tone ska aimed to counteract a segregated England

The 2 Tone record label, spearheaded by the Specials, popularized second-wave ska in the late ‘70s, which married British punk with Jamaican rhythms. The music—intentionally multicultural and performed by multiracial bands—was a response to England’s growing nativism.
