Memes can be traced back to the chain letter

Memes emerged in the 1980s and 1990s

Today's Internet users might think of memes as references spread online through images, videos, and audio clips. But the merger between memes and the internet didn't happen until the 1980s and 1990s—years after the term meme was first coined to describe a different phenomenon.

Memes are 'ready-made language'

Internet memes—groups of texts with shared core content, medium, and stance—are what we, as creators and consumers, make of them. Through their seemingly innocuous and irreverent design, these "bite-sized" transmissions have become vehicles of misinformation, conspiracy, propaganda, activism, and subversive messaging.

Biologist Richard Dawkins coined the term 'meme'

His 1976 book "The Selfish Gene" proposed that units of culture could be replicated, passed on, and evolve as they were transmitted, similar to human genes. He called this unit a "meme," to be pronounced like "cream."

A joke about mercury in an elevator led to the invention of emoticons

A false message about mercury contamination was posted in response to a physics problem on Carnegie Mellon's discussion board in 1982, which some users took seriously. The need to indicate which messages were jokes led to the creation of facial expressions using special characters.

How Chuck Norris 'Facts' gave birth to the modern meme

In the early 2000s, anonymous, absurdly hyperbolic jokes about one B-level action star suddenly appeared everywhere on the internet. "Chuck Norris Facts" were spawned by a high school senior, who'd noticed something funny online and taken it to the next level. As Ryan Hockensmith shows in this detailed history, Spector's joke laid the groundwork for the modern meme.

Memecoins are a type of cryptocurrency—a form of digital currency with a wide variety of uses—created around popular 'memes,' or viral internet jokes.

The history of malware includes computer viruses, worms, trojans, and ransomware

Some of the earliest significant pieces of malware—the Creeper worm and the Elk Cloner virus—displayed silly messages to users without causing major harm. As computer science has advanced, malware has become more easily spread, incorporated social engineering to manipulate users, targeted infrastructure systems, and been used by governments for virtual espionage.

Why millions of telegrams are still sent every year

Telegrams enabled much faster communication across distances when they were invented in the 1800s, but they became generally obsolete after emails and cell phones were widely adopted. So why are 17 million still sent every year? A combination of factors: the legal requirement to send paper documents far and fast, the resistance to updating processes, and nostalgia.

'Creepypasta' is a meme that has its roots in folklore

The genre of crowdsourced, horror folklore comes from copypasta, a term that refers to snippets of content copy-and-pasted online ad nauseam. These memes' allure stems at least partly from how they seemingly rise from nowhere, with tales crafted by many hands over many iterations.

What is a reply all email storm?

When 30,000 people receive an email, to which anyone can "reply all," a spontaneous chain reaction of many more messages can be sparked, producing what's known as an "email storm." This has happened at a large scale in several high-profile cases, most notably in Thomson Reuter's email database. Check out Know Your Meme's breakdown of this phenomenon and description of several major examples.

The story behind one iconic meme

The 2012 post titled "Just a book owners smile" shows 11-year-old Maggie Goldenberger—resplendent in her braces, pigtails, and treasure map-like vest—holding a trio of Goosebumps books and grinning wildly at the camera. Another user quickly captioned it, "GERSBERMS. MAH FRAVRIT BERKS."

X (Twitter) started as a way to share short updates via text

What began as a way to share 140-character updates quickly grew into a vital platform for activism, politics, and pop culture. Hashtags, trending topics, and retweets—now common across the internet—originated on the platform.

Measles reached global transmission during the 15th- and 16th-century Columbian exchange

A look at historical ciphers, from the Spartan 'scytale' to the Navajo Code Talkers

From the Greek word for "hidden writing," cryptography in Ancient Greece took the form of batons around which a long strip of leather or parchment was wrapped, after which messages were written. Recipients needed a scytale of the correct width to encircle received ribbons and reveal the message. Members of the Navajo Nation created a code that remained unbroken throughout its use in World War II.

Many believe modern fan fiction began with 'Star Trek'

While people have always reinterpreted preexisting stories, fanfiction is often noted for its communal, interactive element, which many believe started with the TV show "Star Trek." Fans were so passionate about the show that they began creating stories set in the show's universe and sharing them with fellow superfans through conventions and self-published fanzines, like 1968's "Spockanalia."

The history of rickrolls (this isn't one)

Rickrolling describes a bait-and-switch meme in which a seemingly relevant hyperlink takes clickers to videos or gifs of Rick Astley’s 1987 single, “Never Gonna Give You Up." It's possible this seemingly ubiquitous internet prank can be traced to a 2006 segment of a radio show in rural Michigan. Erik Helwig called into the show during a listener comment segment and, without saying anything, played Astley's single for all those tuning in.

Grandmaster Flash’s ‘The Message’ set the template for hip-hop composition

This 1982 single is one of the most recognizable beats in hip-hop history, thanks to some inspiration from popular disco and new wave records. The song’s bigger contribution, though, is that it pushed lyrics front and center, turning the rapper from a party-rocking master of ceremonies into a truth-telling MC.

Graffiti dates back to at least ancient Pompeii, where citizens scrawled messages to one another on public walls

Pre-coin currencies like shells were subject to counterfeiting

While it is difficult to pinpoint the very earliest form of money that was used, a type of shell called cowrie shells were used as currency as far back as 3300–2000 BCE. These shells were imitated using ivory, bone, clam shells and more.

Peptides may have predated ribosomes—the cell's protein factory

Some scientists have hypothesized that peptides and RNA molecules may have coevolved as a single, mixed "chimeric" molecule, fueling the beginning of protein production and predating a primitive version of the ribosome. All life today uses ribosomes to make peptides. (Some users may experience a paywall.)

Changing a single letter in DNA can permanently alter an organism

Genetic mutations occur when cells replicate, which requires a copy of DNA to be created, and involve substituting, deleting, or inserting letters in a cell's genetic code. Mutations can be caused by normal cellular processes, chemical exposure (e.g., carcinogens), or radiation and may result in genetic disorders or genetic variations that drive evolution.

Breaking down how Dickinson viewed letters as an extension of her poetry

The poet's many correspondences were dashed with playful arrangements of text, offering her pen pals surprises once they opened their envelopes. Jana Dambrogio and Daniel Starza Smith explain how Dickinson even creatively used the 19th-century security technique of letterlocking in poetic ways.

Synaptic plasticity allows neurons to communicate effectively and form memories

First proposed in 1949, synaptic plasticity allows the brain to adjust communication strength between neurons. This ability to change synaptic strength—either briefly or over long periods—is essential for learning and memory, with long-term synaptic plasticity forming the basis of how memories are stored.

Mark Twain invented an unsuccessful board game

“Memory Builder” was based on pinning historical events in their correct chronological order. It was test-marketed in 1891, but never took off. One critic said, “The game looked like a cross between an income tax form and a table of logarithms.”

The word 'toasting' goes back to the 17th century

The act of clinking drinks and wishing fellow revelers good fortune is an ancient tradition, but the term for it dates back to the late 17th century. Although there are numerous explanations for its origins, the most likely is that people associated the act with the toast placed in wine, which provided flavor and absorbed acidity.

A 2019 Facebook event called on attendees to "Storm Area 51, They Can't Stop All of Us," resulting in countless memes, the creation of a music festival, and eventually the arrests of those who did try to approach the area.
