The adaptation effect

According to internal metrics released by Netflix, book-based adaptations accounted for 20% of total viewing hours in 2025, totaling approximately 9 billion global views. This viewership has translated into measurable gains for both frontlist and backlist titles across multiple formats.

The impact of screen adaptations on book sales is particularly evident in the performance of specific titles released in early 2026. Alice Feeney’s 2020 psychological thriller, His & Hers, reached #15 on Amazon’s bestseller list following its series debut in January. During the same period, Spotify reported a 494% increase in audiobook consumption for the title.

Similarly, the film adaptation of Emily Henry’s People We Meet on Vacation led to a 97% increase in sales across all formats within two weeks of its release. Spotify also recorded a 515% jump in global listens, according to Netflix.

According to Publishers Weekly, Ben Lee, SVP of backlist at Penguin Publishing Group, noted that the title, which already had nearly 3 million copies in print, returned to the New York Times bestseller list following the Netflix premiere.

Data suggests that “tie-in” editions and digital formats are primary beneficiaries of the streaming effect. Jennifer Iacopelli’s YA romance Finding Her Edge saw its paperback tie-in version outsell the original hardcover by 800% in the eight weeks following its debut. The title also experienced a 990% increase in global audiobook listens on Spotify.

The influence extends beyond domestic sales to international licensing. Alice Sutherland-Hawes of ASH Literary reported that the announcement of the Finding Her Edge adaptation facilitated 13 additional translation deals and a U.K. publishing contract within weeks. This trend of renewed international interest was also observed in the backlists of established authors. In the U.K., Agatha Christie’s Seven Dials Mystery saw sales increase fourfold following the premiere of its series adaptation, while in the U.K., Julia Quinn’s Bridgerton series saw sales triple in conjunction with the premiere of Season 4.

The “first look” or announcement phase of production is also proving to be a significant sales catalyst. Miriam Parker, VP and associate publisher at Ecco, stated that the February announcement for Shelby Van Pelt’s Remarkably Bright Creatures nearly doubled the novel’s sales. The book has now surpassed 4 million copies sold as it prepares for a May 2026 release on Netflix.

With a pipeline of high-profile adaptations including 3 Body Problem, Heartstopper Forever, Narnia, and Pride and Prejudice, the publishing industry continues to integrate streaming cycles into its long-term marketing and distribution strategies.
