How BookTok is fueling the streaming boom with book adaptations

BookTok’s rise is reshaping the streaming landscape

The BookTok community—voracious readers who share reviews and recommendations—is transforming the streaming wars. Production studios are increasingly turning to influential creators and pre-existing fanbases to drive viewership, placing their bets on book adaptations to capture audiences.

"To me, it's a way of finding treasure," said Hannah Griffiths, head of adaptations at independent production house Banijay. "It's such a sophisticated readership... they've done a lot of the work for you by sifting and finding the good material."

By the numbers: Book adaptations dominate streaming

Nearly half of the original drama series that premiered on Netflix, Disney+, and Amazon Prime Video from January 2024 to June 2025 were book adaptations, according to a March 2025 report by the Publishers Association.

Among the top 50 highest-grossing films from 2020 to 2024, adaptations earned 57% more at the box office than non-adaptations, per industry data.

Amazon Prime Video’s recently revealed sizzle reel of upcoming projects is dominated by book adaptations that have already cultivated devoted online audiences.

BookTok’s built-in fanbases reduce marketing costs

Griffiths emphasized that BookTok is a highly accessible and dynamic fan base that directly signals what audiences want. She noted that studios often don’t need to spend heavily on marketing, as TikTok’s organic reach drives awareness.

"Production houses don’t really have to spend any money marketing these shows, because TikTok is going to do it for them," she said.

Big payouts for popular titles

While studios rarely disclose deal prices, leaks indicate that sought-after titles can command multimillion-dollar contracts. For example, Amazon MGM secured the movie rights to Rebecca Yarros’ romantasy novel "The Last Letter" for a reported $2 million in 2025 after a heated bidding war.

In 2025 alone, more than 50 million BookTok-recommended books were sold across European markets, generating over €800 million in revenue, according to NielsenIQ BookData.

Success stories fuel future adaptations

The success of certain adaptations is paving the way for future content, proving that the right titles can yield significant returns. For instance:

• "Bridgerton" Seasons 1 and 3 are among Netflix’s top ten most-watched series of all time.
• Season 3 of "The Summer I Turned Pretty" on Amazon Prime Video drew 70 million views in its first 70 days, boosted by BookTok fans who promoted love interests using tags like #TeamConrad and #TeamJeremiah.

Romantasy leads, but fantasy adaptations lag

Most adaptations to date have focused on contemporary romance, even as the romantasy genre—blending romance and fantasy—gains traction. However, fantasy concepts often require more complex visual effects, and major titles in this space have yet to premiere.

For example, Yarros’ bestselling romantasy "Fourth Wing" took an unusually long time to develop. Amazon acquired the rights in 2023, and its adaptation is still in progress.

BookTok provides unfiltered audience insights

Victoria Marini, an agent at the High Line Literary Collective, told Axios that BookTok offers studios real-time consumer data, unlike traditional bestseller lists curated by editors.

"The math informs those editors, but they are ultimately meant to tell a story of what the country is reading. Whereas BookTok data, no one is filtering that data to tell a story. It's just raw, and that makes
