New York — Roger Ailes, who built Fox News into a powerful cable giant that transformed both American television and politics, has died at the age of 77, the network announced on Thursday.
The Fox co-founder, a consultant to Republican presidents widely credited with leading a revival of the US conservative movement, was ousted from the network last year under the cloud of a series of sexual harassment allegations.
A friend of media titan Rupert Murdoch, Ailes was seen as a central figure in the conservative US political movement, who stood down at Fox in July last year after a sexual harassment lawsuit from former news host Gretchen Carlson.
His wife’s statement, first published on the conservative Drudge Report, said: "I am profoundly sad and heartbroken to report that my husband, Roger Ailes, passed away this morning."
Ailes, she said, "was a loving husband to me, to his son Zachary, and a loyal friend to many. He was also a patriot, profoundly grateful to live in a country that gave him so much opportunity to work hard, to rise — and to give back."
There was no immediate indication of the cause of death.
Under the leadership of Ailes, Fox became America’s most widely watched cable news channel, home to key conservative political commentators and drawing an audience distinct from rivals CNN and MSNBC.
"Today America lost one of its great patriotic warriors," said Fox News host Sean Hannity, in a tribute to his friend and mentor read out on air.
"Few people in this life will ever reach for the profound level of impact that Roger Ailes had on the country," Hannity said. "As his opponents played checkers in life Roger was always the strategist, playing chess five steps ahead at another level."
By creating a cable news giant which became a favourite of conservatives, Ailes became a central US political figure.
In the 2008 book, Dark Genius: The Influential Career of Legendary Political Operative and Fox News Founder Roger Ailes, political scientist Kerwin Swint described Ailes as "the dominant media figure of our time", who "radically altered our political and communications landscape".
Ailes served as a consultant to presidents from Richard Nixon to Ronald Reagan to George HW Bush and, according to some analysts, helped revive conservative politics in the US. He was also reported to have advised President Donald Trump in the 2016 campaign.
"Apart from the presidents he served, he was arguably the single most important figure in the creation of modern conservatism," David Greenberg, a Rutgers University political scientist, wrote in an essay for Politico last year.
"By fusing television’s power to conjure feelings of anger and resentment to an ideology of cultural populism that demonised liberal elites, Ailes set forth the methods and the message that would help conservative politicians win and maintain power for decades."
