Wondering what commercial fiction is? When authors describe their books, they usually describe them as either “genre” or “literary.” Genre books encompass mystery, romance, science fiction, horror, and other popular categories. Some books are classed as mixed genres, like dark romance or historical fiction.
Genre books are plot-based. They follow strict rules about what readers expect in terms of characters, settings, dialogue, ending, and—most importantly—a plot that keeps readers turning the pages. You can still find high-quality characters and excellent writing in a genre book, but these don’t matter if the plot doesn’t keep the pages moving.
Literary books, by contrast, are character-based. These books are noted for their beautiful language and the way they express themes that matter to the writer. They may have loose, aimless plots, ambiguous endings, and unrelatable characters. A genre novel wants to tell a good story. A literary writer wants their book to explore what it means to be human.
One type of genre book is the type that’s classified as strictly commercial fiction. This is a book whose aim is to appeal to a large audience. Commercial fiction is written with an eye on market trends. The writers don’t spend much time developing themes or crafting perfect sentences. Commercial fiction is an umbrella term covering a wide range of genres.
These are the books you’ll see in airport displays, commanding center stage in bookstores, or being turned into movies. The goal of commercial fiction is to entertain. They’re sometimes called “escapist” because commercial fictions gives readers a chance to immerse themselves in another world.
Commercial fiction books are often criticized for being lightweight and badly written. They are considered to have less artistic merit than literary fiction. That criticism has merit. Some of the world’s best-selling books are poorly written. They’re crammed with cliches, doubtful grammar, and clunky wording. They play fast and loose with historical facts or legal procedures. The saying that “being popular doesn’t mean it’s good” certainly applies to commercial fiction books.
That said, there are genre writers who produce beautifully written, thematically rich, and thought-provoking commercial fiction books. Some have been made into movies that are works of art. Readers shouldn’t dismiss them just because they’re commercially successful.
There’s no question that this commercial fiction makes money. Importantly, it is the economic engine of the publishing industry. Publishers know they’re going to make money from these writers, so they are more willing to invest their resources in printing and marketing books with their bylines. Writers, agents, marketing firms, and others all enjoy the profits these books bring in. The success of commercial fiction ensures that publishers and bookstores stay in business.
One writer who crossed all these genres in his career was Mario Puzo, author of The Godfather. Puzo was a struggling writer in Brooklyn who had repeatedly failed to get readers interested in his literary works. His published novels received critical acclaim, but they didn’t make much money.
However, he often entertained his friends with what he called his “Mafia stories” about his life growing up around Italian gangsters. His friends urged him to use those stories in future books. On the brink of bankruptcy, he finally decided to write a purely commercial book about a Mafia family. He sold it to the commercial house G.P. Putnam’s Sons in 1965.
It was published in 1968. By then, he was so broke, he was ready to tell his wife that they would have to sell their house. Before that happened, he learned that the publisher had sold the paperback rights to The Godfather for $400,000, which would equal $3 million in today’s money. Puzo thought his agent was playing a prank on him when he got the call.
The book was a blockbuster that broke all earlier sales records. By 1971, it had sold 7 million copies.
Shortly after that, Paramount Studios made him an offer he couldn’t refuse: to turn The Godfather into a movie. The studio hired him to co-write the script with director Francis Ford Coppola. Released in 1972, the movie had huge critical and commercial success. Puzo won an Oscar and became a professional screenwriter. To this day, the script and movie of “The Godfather” are regarded as some of the greatest in American film history.
Later in life, Puzo said he initially felt bad that he had “sold out” his literary ambitions for money. He noted that people didn’t even know he had written other books. But he made peace with the fact that “Through The Godfather, I came to my true gift: a storyteller.”
Do you have some exceptional stories that will grip readers’ imaginations? If so, you may have what it takes to write a commercial fiction blockbuster.
To write a commercially successful book, focus on these key characteristics.
Some writers have sold so many books that they’ve become synonymous with their genres. These writers got to the top early and remain dominant.
These are writers who climbed to the top and stayed there. In recent years, writers like Gillian Flynn, Colleen Hoover, Liane Moriarty, and E.L. James have dominated the best-seller lists, but it isn’t clear that their books will continue to top sales lists for decades.
King exemplifies the enduring power of becoming known for a specific genre. With over 300 million books sold and countless movie and TV adaptations, he is known as the “King of Horror.” King’s books have created a cultural impact for decades. He broke through in the 1970s and dominated the bestseller lists for 20 years. His books continue to generate sales because readers know to expect horror blended with universal human themes and compelling characters.
Brown excels at creating hooks that readers can’t put down. Take his smash bestseller The DaVinci Code. Its premise involves a race to solve a murder, uncover a religious conspiracy, and find clues in famous works of art. The action takes place across historical eras and world-famous locations. The reader knows that the stakes are high, and the conflict is clear. The book also highlights the importance of market research and controversy to drive sales.
Author of the surprise bestseller Girl on the Train, Hawkins is an excellent example of an author who straddles the line between commercial and literary fiction. The suspense novel combines a fast-paced plot full of twists and turns, the hallmarks of commercial fiction, with other elements, like the unreliable narrator and psychological depth, which characterize literary fiction. It’s an example of how a novel can achieve both critical and commercial success.
If you want to write commercial fiction, study the writers who have made it to the top. Focus on plot, engaging characters, and a solid hook. Become a storyteller who lets readers escape their everyday lives.
