Quiz Books Soar as Non-Fiction Sales Decline: Surprising 2025 Trends

New data reveals quiz books saw a remarkable 25% rise in readership in 2025, bucking the downward trend in non-fiction publishing. Bibles also proved popular as overall book sales fluctuated.
Quiz books have emerged as an unlikely hero in the publishing industry, defying the overall decline in non-fiction sales, according to the latest data from NielsenIQ BookData. In 2025, quiz book spending increased by nearly a quarter, marking the best year for the genre since records began in 1998.
The surprising data suggests that while many readers may be gravitating away from traditional non-fiction titles, they still have a strong appetite for interactive, engaging content that quiz books provide. This trend highlights the evolving preferences of modern book consumers, who are increasingly seeking out formats that offer a more immersive and participatory reading experience.
