Fan fiction has slowly become a part of mainstream publishing

Several bestsellers began as fan fiction

Ali Hazlewood's "The Love Hypothesis" began as "Star Wars" fan fiction. Cassandra Clare's "Mortal Instruments" series was about "Harry Potter" characters Draco Malfoy and Ginny Weasley. Anna Todd's "After" series was an example of "real life fiction," or fan fiction that is about real people rather than fictional ones (the books were originally based on the boy band One Direction).

Fanfiction proliferated on fan-made sites in the 1990s

As the internet became more accessible in the '90s, fanfiction writers created websites dedicated to publishing stories about their favorite characters. Still, the hobby was far from mainstream. As one writer from that time said, "Going to Star Trek/comic book conventions in the '80s and '90s was something nerds did. Telling people you read or wrote fan fiction put you in the super geek category."

Fan fiction is now studied at universities, including Princeton and Harvard

Some professors approach the genre as a unique form of literature that expands the boundaries of art. Comparative literature courses read the source material as well as its fan fiction byproducts, asking students to analyze the conditions that might've produced such dramatic reinterpretations.

'Harry Potter’ transformed the young adult publishing industry

The series’ success reshaped the market for youth fiction. In 1997, about 3,000 young adult titles were published annually. By 2009, that number soared to 30,000 as publishers chased the next major phenomenon.

One data scientist argued that fan fiction improved writing

In an academic study, University of Washington professor Cecilia Aragon found that fan fiction often teaches young writers how to craft stronger sentences and convey complex ideas effectively. Much of that comes from the larger fan fiction community, which regularly comments on others' stories, offering kind-hearted constructive criticism in what she calls "distributed mentoring."

One writer believes fantasy is a form of realism

The literary genre has become massively popular in the 2020s, turning a previously marginal form into a mainstream concern. Spufford, a literary novelist who grew up loving books that explored fantastic worlds, argues that fantasy is so popular because it so accurately reflects the real world.

If a publisher wants to sell fan fiction, they encourage writers to change key details

Historically, companies that publish popular fan fiction have their authors change a few details—like character names, settings, or other details—to avoid potential copyright violations. Many believe the risk is worth the reward, though the legality remains murky. (Some users may experience a paywall.)

One 'Harry Potter' fan fiction deals with cognitive science and philosophy

Eliezer Yudkowsky's "Harry Potter and the Methods of Rationality" is not your typical fan fiction: It uses JK Rowling's fictional universe to wrestle with rationalist philosophy and the physics behind the magic taught at Hogwarts. The book went on to become popular in Silicon Valley, especially in the effective altruism movement.

Fan fiction implies art is an ongoing, communal practice

Although some serious literary types disregard fan fiction, other academics consider it a fascinating development in art and communication, one that allows everyday people to participate in worldbuilding and storytelling.

'Harry Potter' became one of the most successful franchises in history

What began as a story written in cafés by an unknown author grew into a global phenomenon—spanning seven books, eight films, theme parks, and video games—reshaping modern popular culture.

Modern fan fiction exists in a legal gray area

Modern copyright law prohibits using someone's intellectual property (like a character) without their permission. By and large, fan fiction is tacitly condoned by copyright holders because it's commonly distributed for free. If anything, the copyright holders often benefit by allowing passionate fan communities to flourish.

The US paperbacks of JRR Tolkien's 'Lord of the Rings' series transformed fantasy from a fringe literary genre to a mainstream form.

Fanfic can provide fans with wish fulfillment

Rather than complaining about a writer's decisions, fan fiction is interactive, providing the fandom with the opportunity to tell the story in the way they see fit. That's especially evident in "shipping," a popular fan fiction trope that's focused on the romantic pairing of characters who are not romantically involved in the source material.

Some fan fiction allows readers to place themselves in their favorite stories

One subgenre of fan fiction is called "self-insert." It's exactly as it sounds: The form takes a preexisting story and inserts a reader proxy into the world of the story, acting as a form of wish-fulfillment.

Fan fiction relies on tropes and subgenres

Fan fiction sites often appear to be littered with inscrutable codewords, with stories labeled as "AU," "drabble," or "PWP." These alert readers to elements of a fan fiction: "AU" is an alternative universe narrative; "drabble" is a very short story; "PWP" stands for "plot? What plot?"

Unpacking the rapid rise of romantasy, the genre that blends fantasy and romance

The subgenre—primarily aimed at female readers and sometimes bordering on erotica—has become a sensation, due in no small part to its popularity on social media platforms like TikTok. Writers like Sarah J. Maas and Rebecca Yarros harken back to early Gothic works, which similarly sought to combine the supernatural and the erotic.

The success of 'Fifty Shades' raised questions about fan fiction and copyright

James might've revised her "Twilight" fan fiction book "Master of the Universe" before it was republished as "Fifty Shades of Grey," but studies found that the two manuscripts were essentially the same text. Some wondered whether that meant Stephanie Meyer, author of "Twilight," was entitled to royalties, though Meyer never pursued legal action.

Many believe modern fan fiction began with 'Star Trek.'

Fan fiction is an unauthorized reinterpretation of a copyrighted story

Writers have always reinterpreted and retold others' stories. (John Milton, for example, used characters from the Bible in "Paradise Lost.") Fan fiction, though, refers to unauthorized, creative retellings of copyrighted stories intended for other fans.

The 21st-century novel is increasingly autofictional

Although autofiction, a literary genre blending autobiography and fiction, has been around for millennia, it has become a popular mode in the 21st century. This extensive study of the genre—which analyzes works by Megan Boyle, Tao Lin, and others—argues that the form has become more prevalent because it mirrors the defining technology of the times: social media.

Lucasfilm discouraged fan fiction that sexualized its characters

The self-published fan fiction zines of the '60s, '70s, and '80s were obscure enough that they rarely attracted the attention of the copyright holders of their source material. But Lucasfilm, the production company behind the "Star Wars" films, threatened legal action against fans who published X-rated stories and "homosexual expressions of love" featuring its characters.

EL James' 'Fifty Shades of Grey' was originally 'Twilight' fan fiction

The first volume in the popular erotic romance series was originally called "Master of the Universe" and focused on the main characters of "Twilight," the popular vampire series by Stephanie Meyer. After it became a hit in fan fiction communities, James removed the references to "Twilight" and changed the title. It would go on to be the fastest-selling paperback of all time in the United Kingdom and lead to additional books and film adaptations.

Writers like Colleen Hoover and Emily Henry have propelled romance to become the most popular genre in publishing, generating over $1B annually.

Consumers are buying more books now than they were 20 years ago, thanks to a 2020 boom and a popular literary corner on TikTok.

Jane Austen inspired stories that some now consider fan fiction

Sybil G. Brinton's 1913 novel "Old Friends and New Fancies" brought together characters from Austen's six major books. Other works of JAFF (Jane Austen Fan Fiction) followed in the same style. The books appealed to the budding group of Janeites, a term referring to Jane Austen superfans.

In 2000, The New York Times introduced a separate bestseller list for children's books after Harry Potter titles occupied top spots on the main list for more than a year.

Fantasy is a genre that relies on the supernatural

Fantasy is a literary genre that embraces supernatural and magical elements. While the stories often follow common narrative archetypes, like a quest, they frequently take place in elaborately constructed worlds, which sometimes have their own complex physics, lifeforms, and societies.

Fantasy has dozens of subgenres

“Fantasy” itself is a rather broad way of characterizing fiction. The genre encompasses many subgenres, including epic (like JRR Tolkein’s “Lord of the Rings”), dark (like Neil Gaiman’s “Coraline”), or even superhero (like your favorite Marvel or DC comics).

Hockey romance novels have become an unexpected sensation

The combination was not an obvious hit, but books like "Hockey With Benefits," "Body Check," and "Puck and Prejudice" (a Jane Austen fan fiction) have grown popular thanks to a romance novel boom and an interest on TikTok. Now, HBO and Amazon are taking note with streaming adaptations. (Some readers may experience a paywall.)

Readers discovered AI prompts in several romantasy books

In 2025, readers discovered AI prompts in three writers' texts, with one even instructing the AI bot to make a passage sound more like another romance writer. This Futurism piece digs into the scandals and how it's contributed to readers' skepticism about the genre's more prolific writers.

How 'Star Wars' changed science fiction

The popularity of "Star Wars" shifted the market away from the more literary, and sometimes cynical, science fiction of the 1960s and '70s. In the wake of George Lucas' space opera, publishers and studios wanted similarly optimistic adventure stories. In time, though, writers like William Gibson would react against that and, in turn, create the "cyber punk" subgenre.

Science fiction or new technology?

Dystopian literature is no longer relegated to the page, with innovations like the Tesla Cybertruck and Meta virtual reality headsets mirroring the aesthetics of texts like "The Running Man" and "Neuromancer." In this essay, Casey Michael Henry argues that the images from these works remain while their messages have faded.

Why dystopian literature remains popular

Yale English professor Joe Cleary argues that dystopian literature’s continued relevance is due to a torrent of additional societal anxieties and that the streaming adaptations of dystopian classics "The Handmaid’s Tale" and "The Man in the High Castle" have expanded the genre’s popularity, introducing new audiences to its tropes.

Early reviews turned ‘Harry Potter’ into an unexpected hit

Though only 500 hardback copies of "The Philosopher’s Stone" were printed in 1997—and mostly sent to libraries, due to doubts it would sell—glowing reviews and word of mouth fueled a surge in demand. Within a year, the book had sold more than 70,000 copies in the UK.

Romantasy fans explain why they think the genre is so maligned

Romantasy grows more popular every year, but that doesn't mean it's taken seriously as literature. Hosts from KPBS' "The Finest" attended Comic Con 2025 to get romantasy fans' takes on the genre's unserious reputation.

The ‘Harry Potter’ franchise is valued at more than $32B

Combining book sales, films, theme parks, and merchandise, Harry Potter ranks among the world’s highest-grossing media franchises—estimated at more than $32B in total value, alongside giants like Star Wars and Marvel.

How Harlequin became the most famous name in romance fiction

The publisher, which began as a modest family operation in 1949 in Winnipeg, took off when it noticed its bestselling titles were romance novels.

'The Wonderful Wizard of Oz' was the first major American fantasy novel

Baum blended elements of Hans Christian Andersen, the Brothers Grimm, and Lewis Carroll, placing them in an American context. The illustrations of William Wallace Denslow brought the fantastical elements to life, as seen below.

Fantasy and science fiction are distinct genres, though they sometimes overlap

Fantasy stories take place in universes where magic exists; science fiction stories take place in universes that are still grounded in the physics of our world. In science fiction, supernatural powers have scientific explanations. Think of “Spiderman”: Peter Parker gains his powers after being bitten by a radioactive spider.

Dystopian satire became more prominent in the 20th century

Although "anti-utopian" stories have always existed, the international conflicts of World War I and World War II inspired some of dystopian literature’s most influential novels, like Yevgeny Zamyatin’s "We," Aldous Huxley’s "Brave New World," and George Orwell’s "1984." In the decades to follow, more writers would follow the example of those early novels, using the dystopian model to critique artificial intelligence, climate change, and more.

Early English fantasy writers built on horror and Gothic texts

After the success of 19th-century books like Mary Shelley’s “Frankenstein” and Robert Louis Stevenson’s “The Strange Case of Dr. Jekyll and Mr. Hyde,” readers were eager for more stories that deviated from realism. Early 20th-century texts like George MacDonald’s “Phantastes” and Lord Dunsany’s “The King of Elfland’s Daughter” met the moment, laying the groundwork for the fantasy genre.

JRR Tolkien believed fantasy literature was an entirely different world

Tolkien effectively invented modern fantasy, which often relies on an intricate universe, complete with its own languages, cultures, lifeforms, physics, and systems. When an author did this effectively, he called it “Faërie”—a sort of enchantment that transports the reader into the fictional world.
