Barry Diller (born February 2, 1942, San Francisco, California) is an American media executive who led Paramount Pictures (1974â84), Twentieth Century-Fox (1984â92), and IAC/InterActiveCorp (2003â10). He helped create the Fox Network and later built a digital-media and Internet-commerce empire through IAC.
Diller dropped out of the University of California, Los Angeles, and in 1961 he took a job as a mail clerk at the William Morris Agency. In 1966 he began working as a programming assistant at the American Broadcasting Company (ABC), where he rose in the ranks to become a vice president of the company. There he gained acclaim for his successful programming innovations such as the TV miniseriesânotably Rootsâand the made-for-TV movie of the week.
In 1974, Diller moved to Paramount Pictures, where he served as chair and chief executive officer. Under his leadership Paramount became the most successful of the Hollywood studios in the late 1970s and the early â80s, producing such movies as Saturday Night Fever and Raiders of the Lost Ark and the popular television series Cheers.
In 1985, he became chair and CEO of Twentieth Century-Fox and later, under new owner Rupert Murdoch, was given the job of creating a fourth television network. With programs such as MarriedâŠwith Children and The Simpsons delivered by satellite to a hastily assembled group of affiliates, the Fox Network succeeded against all odds.
In 1992, Diller left Fox and purchased QVC, a home-shopping cable network. Two years later he was defeated in his attempt to buy his old employer, which had been renamed Paramount Communications. In the same year, QVC and CBS announced a merger, but it was quickly squelched by QVC investors.
Diller then sold QVC and started on a series of mergers and acquisitions. In 1995 he bought Silver King Communications, Inc., a 1992 spin-off of the Home Shopping Network (HSN), which included a number of local television stations. By the end of the year, Diller had become the chair and CEO of the corporation, which acquired HSN in 1996.
He subsequently merged both Silver King and HSN with the newly acquired Savoy Pictures Entertainment, Inc., to form HSN, Inc. Following the completion of his acquisition of the two cable networks USA Network and the Sci-Fi Channel (now Syfy)âthrough which he acquired assets of the production company Universal Television and gained partial ownership of the international ticket retailer TicketmasterâHSN, Inc., was renamed USA Networks, Inc. (USAI), in 1998.
Diller subsequently merged the companyâs online division, Ticketmaster Online, with the online city guide CitySearch to form Ticketmaster OnlineâCitySearch, Inc. In 1999 he acquired the independent-film studios October Films and Gramercy Pictures, which he merged to form USA Films (which later became Focus Features).
By the turn of the century, Diller had created a vast multimedia empire by consolidating his acquisitions. From 2002 to 2003 he served as the interim cochair and CEO of the Paris-based media conglomerate Vivendi Universal, S.A. USAI partnered with Vivendi in the creation of an American subsidiary called Vivendi Universal Entertainment LLLP.
USAI became the interactive-commerce company InterActiveCorp in 2003. The following year USAI became IAC/InterActiveCorp, which operated such Web sites as Ask.com and the online dating service Match.com. In 2010, Diller stepped down as CEO, though he continued as chair.
In June 2026, Diller, through IAC (which renamed itself People Incorporated effective August 2026), offered to acquire the remainder of MGM Resorts International, in which IAC already owned about a 26% stake. The all-cash proposal of $48.30 a share valued MGM at about $18 billion. Diller said the company was undervalued and that MGM would be better able to pursue its growth strategy as a privately held company. Because he served on MGMâs board of directors, Diller said he would recuse himself from board deliberations concerning the proposal.
Dillerâs personal life was long the subject of speculation until he published his memoir Who Knew in 2025. The book included a candid account of his longtime relationship with fashion designer Diane von Furstenberg, an excerpt of which was published in New York Magazine.
The two met in 1974, began dating soon after, and despite a breakup in the early 1980s, reunited in 1991 and married in 2001. Their relationship defied public expectations: Diller wrote openly about his attraction to men and the fear that once kept his personal life compartmentalized and hidden. Yet he described his bond with von Furstenberg as âan explosion of passionâ that endured for decades.
The memoir added rare depth to a figure often defined solely by his business achievements.
