Media mogul Barry Diller’s ‘revealing’ planned memoir mysteriously pulled from Amazon

An upcoming memoir by media mogul Barry Diller has been mysteriously pulled from Amazon.

It’s unclear if the planned book has been scrapped, delayed, or otherwise. Publisher Knopf and Diller’s office did not get back to us.

Sources first told Page Six about the book back in May, telling us there were some bombshells expected. Perhaps now we’ll never know?

A book deal was never announced by the publisher, but the memoir, “Who Knew,” popped up for pre-sales online with a 2025 release.

A cover image for the book has also been pulled.

Amazon, Target and other retail sites featured promo copy from the publisher saying, “In this revealing memoir, Diller recounts a life spent making deals, careers, and decisions that have changed the course of American culture.”

“Barry Diller has influenced every aspect of American culture for over 60 years. He changed how we watch TV, how movies are made, how we shop, how we consume media, and even how we date,” said the teaser copy of the author, the chairman of IAC and Expedia Group.

The promo verbiage also touted how Diller would detail his private life and business insights in the tome.

But as of this week, the book and any info about it has completely vanished online — and the title has been universally replaced with the words, “Untitled 7877” with the author as “Knopf.”

The billionaire who is married to fashion icon Diane von Fürstenberg started his career as a UCLA dropout working in the William Morris mailroom and rose to become a legend in the movie and TV biz at ABC, Paramount, Fox, and more.

He was the CEO of Paramount when the studio released projects including “Grease,” “Cheers,” “Raiders of the Lost Ark,” “Saturday Night Fever” and “Beverly Hills Cop.”

Diller was also CEO of 20th Century Fox, launching the Fox network and overseeing such seminal projects including “The Simpsons” and “Married… With Children.”

He also put together a deal to buy cable television’s USA Network in the 1990s, and has produced a number of Broadway shows.

Execs who got their starts under Diller include power players Michael Eisner, Jeffrey Katzenberg and Don Simpson.

In 1995, he founded IAC, which owns publishing company Dotdash Meredith, and is headquartered in a Frank Gehry-designed building downtown.
