This bonus episode is from Hot Money, a new podcast from Pushkin and the Financial Times.

When Financial Times reporter Patricia Nilsson started digging into the porn industry, she made a shocking discovery: Nobody knew who controlled the biggest porn company in the world. Now, Nilsson and her editor, Alex Barker, have figured out who the guy was, and much more.

In this episode, the fourth in the series, Patricia and Alex wonder how it's legal for porn sites to host millions of videos uploaded by users. The answer is in the story of an Ohio family in the early 1990s.

It involves a family IT business, an FBI raid and a court case that set the precedent for porn – and for tech giants like Facebook and Twitter.
