Modern fan fiction exists in a legal gray area

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.)

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.

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.

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.

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 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.

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.

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?"

Fan fiction has slowly become a part of mainstream publishing

In 2025, the SenLinYu fantasy novel "Alchemised," which began as "Harry Potter" fan fiction, became a bestseller after being traditionally published; its movie rights were sold for over $3M. The mainstreaming of the genre is due to a combination of factors, including publishing's interest in the hard metrics that fan fiction websites provide.

George RR Martin opposes fan fiction

The "Game of Thrones" author is all for fans creating their own stories, but he finds attempts to commercialize fan fiction distasteful. He's also not interested in reading it. "What I see doesn't affect me, so if you want to do it, I don't care," he said in an interview, "but please don't send it to me."

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.

Graffiti exists in a legal gray area

"Street art" has become a major seller in the art world, yet many states still consider graffiti to be illegal vandalism. Copyright law complicates the situation further, offering protections for "original works of authorship fixed in a tangible medium of expression," even if they've been created illegally.

Some attorneys are using true crime fans to their advantage

True crime fans are notorious for falling down rabbit holes. Now that passionate interest is being exploited by attorneys marshaling influencers to serve as informal public relations representatives, a trend that's blurring the lines between fan theories and reality.

Fair use may shield AI companies from potential copyright violations

AI models are trained on enormous datasets built from content scraped from websites across the internet. Copyright law includes a four-factor test to determine whether copies of content fall under fair use, but the law's enforcement has been inconsistent.

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.

Section 230 is the law that shaped the modern internet—and free speech online

Passed as part of the Communications Decency Act, Section 230 shields online platforms from legal liability for user-generated content while allowing them to moderate it and host speech freely, making it one of the most debated laws governing free expression today.

The original Mickey Mouse's copyright has expired, but Disney still owns the trademark

In 2024, "Steamboat Willie"—the 1928 Walt Disney animation with the first depiction of Mickey Mouse—entered the public domain. While anyone is free to build on the original characters and storyline of "Steamboat Willie," Disney still owns the trademark for Mickey Mouse, so any branding with the character's depiction that appears to be from Disney is off-limits.

Accessing the dark web is legal in the US, the EU, and most countries worldwide

As long as users do not pay for illegal goods or services or acquire illegal content, they cannot be prosecuted. Those on the dark web include academics, researchers, and cybersecurity experts gathering threat intelligence on cybercriminals, cyberterrorists, and state actors, as well as protesters, activists, and grassroots organizers.

How the GNU General Public License ensures software remains free and open

Rather than copyright, the free software license is based on the principles of copyleft—users are allowed to use, modify, and distribute software without charge, provided that any derivative works remain free. The license was introduced in 1989 by Richard Stallman, who founded the Free Software Foundation to promote the accessibility of software.

The man behind Comic Sans, the world's most contentious font

Comic Sans is often used as a joke, but it wasn't intended that way. Its creator wanted something eye-catching and original, something that reminded people of iconic comics like Batman and Watchmen.

The site—which was launched in 2008 by 3D-printer manufacturer MakerBot—hosts more than 2 million user-generated design files to build everything from prosthetic hands to replacement dishwasher parts (or the "Golden Snitch" from "Harry Potter). The community behind it rapidly designed and shared files for face shields and ventilator components amid the COVID-19 pandemic.

Postmodernism is a cultural movement that valued pluralism

Postmodernism is an artistic movement (in architecture, fashion, music, literature, and more) that embraced fragmentation, eclecticism, pastiche, and pluralism. The movement's practitioners reacted against modernism, which valued Enlightenment ideals, high culture, and clean aesthetics.

Learn why modern scientific patterns have been described as theories rather than laws

After confirming that the accuracy of some laws of physics is limited to certain domains, science became more hesitant to categorize identified mathematical relationships, such as quantum mechanics, as unchanging laws. Instead, these recent, complex frameworks are designated as theories to acknowledge that they are conditional and may be part of a larger, more complete future framework.

Art theft is the third-largest source of criminal revenues worldwide, thanks in part to the subjective nature of valuing a work of art.
