"Today America lost one of its great patriotic warriors".
In the 2008 book, "Dark Genius: The Influential Career of Legendary Political Operative and Fox News Founder Roger Ailes", political scientist Kerwin Swintdescribed Ailes as "the dominant media figure of our time", who "radically altered our political and communications landscape".
Fox News host Sean Hannity tweeted a message of condolence.
Two weeks later, Ailes was ousted from the network with a $40 million severance package.
According to a Palm Beach police report, a caller contacted 911 dispatchers just before 2 p.m. on May 10, saying Ailes had fallen in his bathroom, hit his head and had serious bleeding. "After all he built in his career, he for all practical purposes died alone".
Former president George H.W. Bush said he loved Roger Ailes, and a Democrat remembered the former Fox News chairman for his love of America.
Rick Folbaum, an anchor for CBS's local news station in Miami who previously worked for Fox News, reflected on Alies and the sexual harassment scandal that dominated the past year.
In 1996, after making CNBC the most successful business network in history, Ailes convinced News Corp Chairman Rupert Murdoch to launch an iconoclastic and fearless news channel at a time when the legacy liberal media virtually monopolized the airwaves.
Gabriel Sherman, who wrote a biography about Ailes, said the media giant "revolutionized politics and made it entertainment". Fox rose to the top of cable news ratings in the 2000s, with the center-right channel dominating its far-left competitors CNN and MSNBC.
The crowning achievement, however, was sullied in his final months by the charges of sexual misconduct. That total included a $20 million settlement in September to former Fox and Friends co-host Gretchen Carlson, who filed suit against Ailes. Carlson alleged that she was sacked for rebuffing Ailes' advances.
