NEW YORK (AP) —   Roger Ailes (aylz), who transformed TV news by creating Fox News Channel, only to be ousted at the height of his reign for alleged sexual harassment, died Thursday, Fox News reported. He was 77.

Authorities in Florida are saying Roger Ailes died of bleeding on the brain caused by an earlier fall at home.

The Palm Beach County Medical Examiner’s Office says the Fox News Channel founder died of a subdural hematoma — or bleeding on the brain — caused by the fall. The death has been ruled accidental and there was no evidence of foul play.

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.

A former GOP operative to candidates including Richard Nixon, Ronald Reagan and George H.W. Bush, Ailes later turned his media savvy to running TV networks. In early 1996 he accepted a challenge from media titan Rupert Murdoch to build a news network from scratch to compete with CNN.

That October, Ailes flipped the switch on Fox News Channel. It became the audience leader in cable news. It also emerged as a powerful force on the political scene, while the feisty, hard-charging Ailes swatted off criticism that the network he branded as “Fair and Balanced” had a conservative tilt.

He was abruptly dismissed from Fox News in July 2016 in the wake of a lawsuit filed by former anchor Gretchen Carlson accusing Ailes of sexual improprieties.
