Ted Turner, the brash media mogul who created CNN and revolutionized how Americans watched television, and who wielded his media empire and wealth to pursue liberal global causes and land conservation, has died. He was 87.

Turner died Wednesday, according to his family.

In 2018, he revealed he had been diagnosed with Lewy body dementia, a neurodegenerative disease, which had been progressing in recent years.

Turner’s outsize public persona — some called him the “Mouth from the South” for his freewheeling trash talk — matched the Georgian’s influence on news, politics, sports and entertainment in the late 20th century. Turner repeatedly shook up established industries by invading quickly and expanding options for consumers, while railing against monolithic competitors who were less daring or nimble than his maverick Turner Broadcasting System.

Turner created the cable stations TBS, TNT and Turner Classic Movies; he owned the Atlanta Braves baseball team, the Atlanta Hawks basketball team and revitalized professional wrestling with World Championship Wrestling.

Turner was one of the first adopters of cable and satellite broadcasting technology, and for many rural Americans living beyond the tower signals of major cities, he was the first person to bring them interesting TV.

The media baron constantly generated headlines. He had a Clark Gable pencil mustache, raced sailboats, cavorted with the late communist leader Fidel Castro in Cuba, and at one point married Academy Award-winning actress and activist Jane Fonda. His wealth enabled him to become one of the largest private landowners and wealthiest philanthropists in the United States.

His crowning cultural achievement was the creation of the Cable News Network in 1980, which created the model for today’s cable news titans. The 24-hour news channel was not widely expected to be a success. All-night broadcasting had not been proven as a business model in an industry dominated nationally by corporate monoliths ABC, NBC and CBS, where news programming was something that happened on a set schedule. And CNN’s headquarters weren’t in media centers such as New York or Los Angeles, but in Atlanta.

Turner believed that “over-the-air networks would decline as audiences turned to videos and other outlets for entertainment on demand,” wrote the late journalist Daniel Schorr in a 2001 memoir.

“The network future belonged to whoever would deliver what was happening now — live news and live sports. That was why he wanted to be the first to deliver all news, all sports, all the time,” wrote Schorr, whom Turner courted to join CNN.

Within two years, CNN had more than 9 million subscribers. By the 2000s, Turner’s once far-flung idea for an around-the-clock news service had become so successful that it had attracted imitators such as MSNBC (now called MS NOW) and Fox News.

“We not only became profitable, but also changed the nature of news — from watching something that happened to watching it as it happened,” Turner said of CNN in 2004. “If we needed more money for [broadcasting from] Kosovo or Baghdad, we’d find it. If we had to bust the budget, we busted the budget. We put journalism first, and that’s how we built CNN into something the world wanted to watch.”

Fox Corp. Chairman Emeritus Rupert Murdoch, who was both a rival and friend of Turner’s, said his “vision for 24-hour cable news transformed the media industry and gave viewers everywhere a front seat to witness history unfold. His impact as a trailblazer has left an indelible mark on our cultural landscape.”

Turner recognized the value of global distribution long before his rivals, launching CNN’s international business in the mid-1980s. He bought his first western property, the Bar None Ranch in Montana, and would eventually become one of the nation’s largest individual landowners with nearly 2 million acres, which provide habitat for threatened species and his beloved American bison.

“Ted’s entrepreneurial spirit, creative ambition and willingness to take risks changed the media industry forever,” David Zaslav, chief executive of Warner Bros. Discovery, which owns CNN, said Wednesday in a note to employees. “He believed deeply in the power of ideas, in doing things differently and in building platforms that could inform, inspire and connect people around the world.”

Robert Edward Turner III was born in Cincinnati on Nov. 19, 1938, and raised in Georgia. A mischievous child — who became a mischievous adult despite attending the Georgia Military Academy (later renamed Woodward Academy) near Atlanta — he had a tough childhood at the hands of his alcoholic father, Ed.

“Ninety percent of the arguments I had with Ed were over his beating Ted too hard,” Ted’s mother, Florence Turner, recalled later.

“My dad ran an old-fashioned household and he insisted that pretty much everything had to be his way,” Ted Turner said in a 2008 memoir. “My father and I had a complex relationship but I loved him.”

The younger Turner attended Brown University but dropped out before graduating. His savings had run out, his father had stopped financially supporting his tuition, and in his final days on campus, he was suspended for bringing a woman to his dorm room, according to his memoir.

He soon joined his father’s expanding billboard company, Turner Advertising, where he had been working off and on for years since childhood.

He inherited the business at the age of 24 after his father died by suicide. By then, Turner had already had years of experience, and he worked furiously to reverse his father’s recent sale of part of the company to a competitor and paid down its daunting debt, an act that presaged the empire-building to come.

While growing the business, Turner also pursued his passion for competitive sailing, which is how he met his first wife, Judy Nye, in college. It’s also how their marriage ended. Turner intentionally hit his wife’s boat during a 1963 race to keep her from passing him, and the pair, who had two children, split immediately afterward.

It was to be the first of three divorces. . “My problem is I love every woman I meet,” Turner said. He would go on to win the America’s Cup in 1977 while expanding his father’s company into a modern multimedia conglomerate.

Leveraging the billboard business, Turner started buying local radio stations across the South in the late 1960s. In 1970, he bought the Channel 17 television station in Atlanta, competing with local network affiliates by airing old movies whose rights were affordable and picking up programming dropped by the less nimble competition. He didn’t like putting news on prime time back then — too negative — and soon picked up broadcast rights for the Braves, Hawks and other local sports.

The Braves were a ratings hit, and when the team flailed and went up for sale, Turner’s company became its owner in 1976. The team continued to flail but Turner boosted its profile with gimmicks such as sewing “Channel 17” on the back of a pitcher’s jersey and dressing up as the team’s batboy and manager, to the league’s disdain. Turner bought the Hawks shortly after.

Facing entrenched local network affiliates, Turner expanded his independent station’s reach across the South and then the U.S. by embracing the new technologies of cable and satellite broadcasting. Channel 17 became nationally known as the “SuperStation,” with call letters WTBS, later shortened to TBS.

The quirky Atlanta station’s local broadcasts of old movies and sports games had become national broadcasts.

Still hungry for more, Turner finally turned his attention to news programming. He launched CNN in 1980 in a desperate bid to create a national 24-hour news channel before the broadcast titans ABC, NBC and CBS — and their gargantuan budgets — could beat him to it.

“The 24/7 genre started with Ted Turner,” veteran CNN journalist Christiane Amanpour said Wednesday on CNN. “He was the original, and he made us all proud, and he made us all hopeful, and he made us all strive for his vision of a better world.”

There were some lean early years. But the nascent channel fended off an attempt by ABC to create a competitor, and critics could see the value of an ever-present news channel, even if quality was a little thin at times.

“Non-viewers of CNN are missing a lot. There are so many reasons to watch,” Los Angeles Times critic Howard Rosenberg wrote in 1986, hailing the six-year-old channel as an “institution.” “It’s not always good, but it’s always there.”

In 1986, CNN was the only broadcaster running live coverage when the Challenger shuttle liftoff ended in disaster. In 1991, the network gave Americans a live and uninterrupted look at the invasion of Iraq. American officials held news conferences knowing that Iraqi leader Saddam Hussein was watching them on CNN.

Americans had seen images of war before, but not broadcast nonstop into their homes.

“CNN seeks to be a stethoscope attached to the hypothetical heart of the war, and to present us with its hypothetical pulse,” the French theorist Jean Baudrillard wrote, critiquing the conflict as a media spectacle. Media scholars began to wonder whether a “CNN effect” was influencing government policy. Officials found that they now had to respond much more quickly to crises unfolding on live television.

Turner was not adversarial to communist countries of the era and even tried his own version of the Olympics, called the Goodwill Games, a bit of private-sector peace-craft that brought the Soviet Union and the U.S. out of their respective Olympic boycotts and back into direct competition in the 1980s. All on television, of course.

Turner also saw professional wrestling as part of his sports portfolio, at one point trying to pit his World Championship Wrestling program against competitor Vince McMahon’s wrestling empire, then called the World Wrestling Federation. Turner similarly tried to take a bite out of MTV with the Cable Music Channel, with a promise “to stay away from the excessive, violent or degrading clips to women that MTV is so fond of putting on.”

Moralism was a Turner hallmark. Turner had started his life as a conservative — he had met his second wife, Jane Smith, at a 1964 fundraiser for Republican presidential candidate Barry Goldwater — but later turned toward more liberal-leaning causes, such as world peace, nuclear nonproliferation and fighting climate change.

At the 1990 American Humanist Assn.’s annual convention, Turner presented his “Ten Voluntary Initiatives” — his atheistic version of the Ten Commandments — which included pledges to world peace, environmentalism, nonviolence and “to have no more than two children, or no more than my nation suggests.” He would become a major private donor to the United Nations, pledging $1 billion and launching the United Nations Foundation.

In 1991, a year marked by the collapse of the Soviet Union, the first U.S. war against Iraq and the confirmation hearings of Supreme Court Justice Clarence Thomas, Time magazine named Turner its “Man of the Year” for his “visionary” creation of CNN, which covered those events live. He also married Fonda that year (the ceremony was reported by CNN) and his Braves narrowly lost the World Series.

Time’s honorific was also a nice bit of corporate synergy. The magazine’s parent company, Time Warner, owned about 20% of Turner Broadcasting System stock.

Turner launched the Cartoon Network in 1992, which helped introduce his then-newly acquired Hanna-Barbera characters — including Fred Flintstone, Yogi Bear and Scooby-Doo — to a new generation of viewers.

Adversaries thought that Turner’s ventures could be reckless and impulsive. Far-seeing accomplishments in national broadcasting and the creation of CNN were also paired with several expensive misadventures, including a failed attempt to buy CBS.

Turner had to unwind a purchase of the MGM film studio less than a year after buying it, though he held onto one valuable asset: The studio’s film library, which became the foundation of the Turner Classic Movies channel and, later, jewels in the Burbank-based Warner Bros. studio vault.

In 1996, Turner Broadcasting merged with Time Warner to form the world’s largest media company, marking the beginning of the end of Turner’s apex in corporate media. Time Warner’s 2000 merger with budding internet giant AOL, then the largest-ever corporate merger, ended in disaster. Turner, who had not been a key player in the negotiations and had made no secret of his disdain for that deal, was fired as an executive.

“Ted Turner was one of the rare leaders who truly changed the trajectory of an industry,” Versant Media Chief Executive Mark Lazarus, a former Turner underling, said in a statement. “I saw firsthand his willingness to take risks and his belief that media could be something bigger and more impactful.”

CNN Worldwide Chairman Mark Thompson added: “He was and always will be the presiding spirit of CNN. Ted is the giant on whose shoulders we stand.”

Turner resigned from the AOL Time Warner board in 2003, and in 2007, announced he had sold his company shares. In his later days, one of his best-known ventures was his Ted’s Montana Grill restaurant chain. His philanthropy and land conservation efforts and protection of the American bison became guide posts during his retirement years.

While CNN maintains influence in the U.S. and abroad, its TV ratings have declined in recent years — a casualty of changing consumer behavior, the rise of social media, derision from President Trump — and several ownership changes.

During the last decade, CNN has had three different corporate owners. The company is poised to be sold again, this time to billionaire David Ellison’s Paramount Skydance. That proposed merger would bring CNN under the same roof as CBS News.

“I’ve often considered and joked about what I might want written on my tombstone,” Turner said in a 2008 memoir. “At one point, when I felt like I could get out of the way of the press, ‘You Can’t Interview Me Here’ was a leading candidate. … These days, I’m leaning toward, ‘I Have Nothing More to Say.’”

Turner is survived by his five children — Laura Turner Seydel (Rutherford), Robert Edward “Teddy” Turner IV (Blair), Rhett Turner, Beau Turner, Jennie Turner Garlington (Peek) — 14 grandchildren and a great granddaughter. The family plans a private service and a public memorial at a later date.
