Geraldo Rivera, Brit Hume, and Laura Ingraham were among the the journalists who praised Ailes in tweets.
Fox News is reporting that Roger Ailes has died at the age of 77. Instead of a hero, some saw Ailes as a promoter of bigotry and fear, who left behind a culture of sexual harassment at the network he built. O'Reilly has denied those accusations.
From the start, Ailes had a clear conservative vision of what he wanted Fox to be as he took the network to the top of the cable news ratings and made it a major profit centre for Mr Murdoch's Twenty-First Century Fox media empire.
As of now, no cause of death has been released, reports CNBC. The death has been ruled accidental and there was no evidence of foul play.
Ailes, who recently purchased a $36 million mansion in Palm Beach, Fla., apparently hit his head after falling in the bathroom of the residence on May 10, according to a Palm Beach police event report. The resulting Fox News eventually became the highest-rated television news network in America, eventually unseating CNN with a staggering 90-million household reach. "His advice to Presidents Nixon and Reagan was historic and helped elect both". In an excerpt from the 2013 biography "Roger Ailes Off Camera", Ailes said he knew his days were numbered.
Ailes had run Fox News under the slogan "fair and balanced" and conservatives found it a much-needed antidote to the perceived liberal slant of traditional media.
Former Arkansas Gov. Mike Huckabee, a former Fox News personality and Roger Ailes' friend, is calling the former Fox chief "a genius".
Ailes was a media visionary, no doubt about it.
During his earlier days as a political consultant, Ailes was a sought-after debate coach, working with Reagan in 1984 and readying then-Vice President Bush for his presidential debates with Gov. Michael S. Dukakis of MA in 1988. Roger was my best friend, the most wonderful loving husband and father to our son Zachary, He was a loyal friend to so many. He suffered from hemophilia, according to a source familiar with the matter.
Few other details were immediately available, including whether the victim was taken to the hospital.
Sean Hannity, perhaps Fox's biggest current star, is rending his garments. "RIP", Ingraham wrote on Twitter.
With news of his death, prominent Fox News hosts and guests shared their remembrances of a man who they say leaves a lasting legacy of altering the American media landscape and political discussions.
Ailes resigned from Fox News under pressure on July 21, 2016 due to numerous sexual harassment allegations. "Roger was a great patriot who never ceased fighting for his beliefs".
Before joining Fox, he served as adviser to several USA presidents, from Richard Nixon to George Bush Senior. Ailes allegedly made frequent advances at Carlson-he reportedly told her during a private meeting that "you and I should have had a sexual relationship a long time ago". The lawsuit quickly triggered accounts from more than 20 women with similar stories.
