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

JRR Tolkien redefined fantasy for a new generation

Tolkien’s debut novel, 1937’s “The Hobbit,” was aimed at young adults, yet it felt far more serious than the whimsical tales of Lewis Carroll or L. Frank Baum. "What Tolkien does is take the 'otherworld' fantasy developed in the 19th century and makes it child-sized, melding it with folklore and Norse myth," notes Farah Mendlesohn, the author of “Rhetorics of Fantasy.”

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.

'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 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.

In 1974, 'Dungeons and Dragons' turned fantasy into a game

Inspired by the fantasy paperback explosion of the late 1960s and early 1970s, Gary Gygax and Dave Arneson published the original incarnation of the game, which immersed players in worlds similar to fantasy fiction. Since then, several newer editions have been released. In recent years, podcasts and livestreams featuring individuals playing the game have gained popularity.

'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. The book was an instant smash hit, selling out its initial 10,000-book pressing within the first eight months. By the time it entered the public domain in 1956, it had sold 3 million copies.

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.

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).

The calendars of the 'Lord of the Rings'

JRR Tolkien's epic fantasy trilogy "The Lord of the Rings" is a seminal work in the history of literature partly due to its creator's obsessive focus on systematic detail—including the calendars used in the world. Take a fantastic dive into the minutiae of Tolkien's creation by learning the different approaches to time organization in the Shire or Rivendell with this dense, comprehensive resource based on Tolkien's appendices.

'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.

JRR Tolkien and CS Lewis met at Oxford and bonded over Norse mythology

The “Lord of the Rings” mastermind and “The Lion, Witch, and the Wardrobe” author were colleagues at Oxford University and shared an appreciation for Norse mythology, which continues to inform the fantasy genre. They were also a part of the same informal literary group, the Inklings, where they’d discuss one another’s works-in-progress.

Check out cheap, mass-market, and often trashy editions of classic books from Ralph Ellison, James Joyce, Jane Austen, and many more.

Lewis Carroll's 'Alice's Adventures in Wonderland' turned the fantasy genre upside down

A lot of 19th-century British fantasy was often stiff; its children’s literature was often overly didactic. Carroll’s novel—about a young girl who falls into an unusual world full—was neither, offering vivid, psychedelic imagery and seemingly nonsensical word games.

Mass market paperbacks—the chunky, cheaply made books—were originally designed to fit in a pocket.

Tolkien's grandson says 'Lord of the Rings' was influenced by WWI

JRR Tolkien fought in World War I, an experience his grandson, Simon Tolkien, says informed the fantasy legend’s famous trilogy. The companionship between Frodo and Sam and Sauron’s pervasive evil, according to the younger Tolkien, were directly influenced by time on the battlefield.

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.

The word ‘fantasy’ wasn't used to describe the genre until the 20th century

The word—at least as a word used to describe fiction—didn’t appear in the Oxford English Dictionary until 1949. Scholars believe that’s due to the arrival of the Magazine of Fantasy and Science Fiction, an influential publication, and the rise in fantasy’s popularity following World War II.

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.

A book series aimed at World War II soldiers helped popularize works like 'The Great Gatsby' and 'Of Mice and Men.'

‘Beowulf’ is a foundational text for modern fantasy

The story is the earliest surviving poem in the English language and enshrined many Anglo-Saxon ideals about heroism, loyalty, and adventure. JRR Tolkein was an enthusiastic fan of the poem, even lecturing about it in 1936, and mirrored many of its themes in “Lord of the Rings.” Critics have also highlighted the influence on later fantasy stories, including “Harry Potter.”

The fantasy-based tabletop role-playing game 'Dungeons and Dragons' has seen a renaissance in the last few years

It's becoming mainstream after being relegated to the dorks for decades. LinkedIn cofounder Reid Hoffman has contemplated the role the game played in his own formation as a person and a business leader.

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.

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

King's books are now taught by college professors

Stephen King’s horror, fantasy, and science fiction were once considered lowbrow and unworthy of serious academic study. That's changed over the last 50 years, with King courses and symposiums taking place at universities around the world.

The first ‘Harry Potter’ book was retitled for US readers

Scholastic changed "Harry Potter and the Philosopher’s Stone" to "Sorcerer’s Stone" in 1998, fearing the original title sounded too academic and might confuse American readers unfamiliar with the word’s magical meaning.

The Beatles tried to get the rights to make a 'Lord of the Rings' film starring the band members as Gollum, Frodo, Gandalf, and Samwise.

'Harry Potter’ became the first kids' book to top the New York Times list since 1952

After its 1998 US release, "Harry Potter and the Sorcerer’s Stone" reached No. 1 on The New York Times Best Seller list—the first children’s book to do so since "Charlotte’s Web." By September 1999, the first three books held the top three spots on the list.

In 1996, King had 6 books on the New York Times bestseller list

Stephen King has been wildly popular for decades, but he was never more visible than in the 1990s—especially for one week in 1996. All six volumes of the serialized novel "The Green Mile" appeared on the New York Times bestseller list. Reading the article not only provides some context for King's ubiquity, but also hints at what would become a norm in publishing: a few big-name authors dominating the charts with their popular series. (Some users may experience a paywall.)

Circulating libraries helped the novel's popularity surge

As literacy rates began to rise in the 19th century, so did the demand for reading materials. The only problem? Newspapers and books weren’t cheap, and newly literate middle-class families struggled to afford literature. That changed when booksellers began offering small fees for patrons who decided to borrow rather than purchase books. This was eventually called a circulating library, an innovation that would satisfy the burgeoning readership of novels and increase literacy rates further.

Ursula K. Le Guin worked to dismantle fantasy's clichés

The author is one of the genre’s most legendary names, constructing high fantasies like “The Earthsea Cycle” that detail intricate new worlds. In 2004, she delivered a lecture criticizing books and movies that rely on a simple formula: white characters, Medieval settings, and a battle between good and evil. “Whenever I find a fantasy that is set in a genuinely imagined society and culture instead of this lazy-minded, recycled hokum,” she said, “I feel like setting off fireworks.”

'Harry Potter' dominance led The New York Times to create a new bestseller list

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.

The printing press spread novels widely

Johannes Gutenberg's invention of the printing press in 1440 changed how writing was reproduced. It allowed multiple manuscripts to be copied via movable type rather than by hand, making more literature more widely available. Over time, that change caused literacy rates to rise, creating a market for even more literature.

JRR Tolkien believed fairy tales needed dramatic reversals of fortune

Tolkien coined the term "eucatastrophe" to define what he believed as an essential key to good storytelling: “The consolation of fairy-stories [is] the joy of the happy ending: or more correctly of the good catastrophe, the sudden joyous ‘turn.'"

Horror exploded as a commercial literary genre in the late 1960s

Ira Levin’s 1967 novel “Rosemary’s Baby” showed publishers horror was a viable commercial genre. That was proven again in 1971, with William Peter Blatty’s “The Exorcist” and again in 1974 with Stephen King’s “Carrie.” The books dealt with societal fears (the occult, drugs, sex) during a time of political upheaval.

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."
