NEW YORK (AP) — Ted Turner could never be defined by just one role. He was a media mogul, philanthropist and conservationist. A yachtsman who won boating’s most famous race and a baseball owner who captured the World Series trophy.

The brash television pioneer who died Wednesday made his greatest mark on the news business when he launched CNN nearly a half-century ago and with it, the 24-hour cable news cycle — a revolutionary moment that transformed the industry.

His media empire grew to include CNN International, the Cartoon Network, TNT and Turner Classic Movies. Then he used his riches to become one of America’s most extensive landowners, dedicating his final years to preserving natural habitats, saving endangered species and reducing nuclear weapons.

Turner died at age 87 while surrounded by his family, according to Turner Enterprises, which oversees his vast businesses and investments. A cause was not released. He was diagnosed in 2018 with Lewy body dementia, a progressive neurological disorder.

A Southerner whose outspoken wit earned him the nicknames “Captain Outrageous” and “The Mouth of the South” during his youthful years, Turner was a celebrity in his own right when he married actor Jane Fonda in 1991, just before being named Time magazine’s Man of the Year.

“If only I had a little humility, I’d be perfect,” he once bragged.

Slowed late in life by his illness and long out of the television business, he concentrated on philanthropy — donating a stunning $1 billion to United Nations charities — and his more than 2 million acres of property, including the nation’s largest bison herd.

His garrulous personality sometimes overshadowed a driven, risk-taking business acumen. By the time he sold his Turner Broadcasting System to Time Warner Inc. in a 1996 media megadeal, Turner had turned his late father’s billboard company into a global conglomerate that included seven major cable networks, three professional sports teams and a pair of hit movie studios.

President Donald Trump on Wednesday called him “one of the Greats of All Time.”

Turner’s signature achievement was creating CNN, the first 24-hour, all-news television network in 1980. It was born of frustration — he often worked late after network newscasts had gone off the air, and was in bed by the time his local stations did their own news.

He took a chance by launching what some called the “chicken noodle network” in the early days of cable television, living in an apartment above its Atlanta office.

“I was going to have to hit hard and move incredibly fast and that’s what we did — move so fast that the (broadcast) networks wouldn’t have the time to respond, because they should have done this, not me,” Turner recalled in a 2016 interview with The American Academy of Achievement. “But they didn’t have the imagination.”

CNN’s breakthrough came during the Gulf War with Iraq in 1991. Most television journalists fled Baghdad. CNN stayed, capturing images of the war’s outbreak, with anti-aircraft tracers streaking across the sky and correspondents flinching from the concussion of bombs.

“His first love was family and he had five children. But very close behind, he’s always told me that his greatest achievement was CNN. But he had so many over the years,” Tom Johnson, CNN’s president from 1990 to 2001, told The Associated Press on Wednesday.

Turner was promised a role in CNN after his company’s sale to Time Warner for $7.3 billion in stock but was gradually pushed out, much to his regret.

“I made a mistake,” he later said. “The mistake I made was losing control of the company.”

That same year — 1996 — saw the birth of Fox News Channel and arrival of a new dominant mogul in cable news, Rupert Murdoch. Turner once compared Murdoch to Adolf Hitler. The bitter rivals later reconciled over environmental concerns.

Warner Bros. Discovery CEO David Zaslav on Wednesday called Turner a visionary and a trailblazer.

“Ted’s entrepreneurial spirit, creative ambition and willingness to take risks changed the media industry forever,” Zaslav said in a note to employees at Warner, CNN’s parent company, which is nearing a mega merger with Paramount.

Robert Edward Turner III was born Nov. 19, 1938, in Cincinnati. When he was 9, his family moved to Savannah, Georgia. After being expelled from Brown University for sneaking a female student into his room, Turner came to Atlanta to work for his father’s billboard company.

His ambitions at that point were broad, he later recalled: “I used to tell people I wanted to become the world’s greatest sailor, businessman and lover all at the same time.”

After his father’s 1963 suicide, Turner took over the company. In 1970, he bought an independent UHF station with a signal so weak it didn’t even cover Atlanta.

On Dec. 17, 1976, he began transmitting the station to cable systems across the country via satellite. It became the TBS SuperStation. “It was the start of something bigger than we ever imagined,” Turner said.

TBS’ collection of old movies and “The Andy Griffith Show” reruns was augmented by Turner’s acquisition of baseball’s Atlanta Braves, which slowly attracted fans across the nation and declared themselves “America’s team.”

Major League Baseball Commissioner Rob Manfred said Turner transformed how fans experience sports.

In the 1980s, Turner went deeply into debt to buy MGM, another move greeted with skepticism.

But the acquisition gave his company a huge library of vintage movies that eventually launched the TNT and Turner Classic Movies networks. His devotion to older movies earned Turner a star on the Hollywood Walk of Fame in 2004. He was also criticized for adding color to classic movies like “Casablanca,” which he said he did to appeal to a younger audience.

TBS also acquired the Hanna-Barbera animation library, which led to the Cartoon Network.

“He sees the obvious before most people do,” Bob Wright, former president and CEO of NBC, told The New Yorker in 2001. “We all look at the same picture, but Ted sees what you don’t see. And after he sees it, it becomes obvious to everybody.”

Asked to share the secret to his success, Turner said: “Early to bed, early to rise, work like hell and advertise.”
