In Who Knew, Barry Diller tells his story for the first time (and what a story it is).

In a career spanning six extraordinary decades, Barry Diller has become one of the most successful executives in media history. Diller's ascent was meteoric, launching ABC-TV's Movie of the Week at age twenty-seven, becoming CEO of Paramount Pictures at age thirty-two, and launching the Fox TV network at age forty-four. Along the way, Diller oversaw the production of classic films such as Saturday Night Fever, Raiders of the Lost Ark, and Home Alone and hit TV shows such as The Simpsons, Married…with Children, and Cops. Along the way Diller tangoed with movie stars and moguls, using his unique management acumen to set the table on his terms. He went on to develop some of the most successful online businesses in the world, including Expedia, Match, and Angi. Indeed, Diller's media savvy changed the course of American culture.

While successful professionally, Diller struggled personally. In Who Knew, he reveals the extent of those struggles with astonishing candor before finding his "unique and complete love," Diane Von Furstenberg. Intimate, candid, and moving, Who Knew is a memoir filled with heart, imbued with humility, and infused with wisdom.
