Millions watch it. Few know who’s behind it. This is the story of the companies who rule the online adult entertainment business.

Streamed by millions every day, porn is everywhere. It shapes our culture, our relationships, and even technology. Yet, nobody seems to know who really controls the business. The power brokers tend to lurk in the shadows, while their performers remain quite literally exposed.

In The Kink Machine: The Hidden Business of Adult Entertainment, two Financial Times journalists, Patricia Nilsson and Alex Barker, start digging into the porn industry and following where the money flows. Their reporting uncovers a shadowy power structure that includes billionaires, tech geniuses, and the most powerful finance companies in the world.

A gripping exposé of how power operates behind the most taboo corner of the internet, Nilsson and Barker unravel a story about control, influence, and an industry with staggering cultural reach that no one really wants to talk about—until now.
