Turner Broadcasting System, Inc. was an American television and media conglomerate. Founded by Ted Turner and based in Atlanta, Georgia, it merged with Time Warner (later WarnerMedia) on October 10, 1996. As of April 2022, all of its assets are now owned by Warner Bros. Discovery (WBD). The headquarters of Turner's properties are largely located at the CNN Center in Downtown Atlanta, and the Turner Broadcasting campus off Techwood Drive in Midtown Atlanta, which also houses Turner Studios. Some of their operations are housed within WBD's corporate and global headquarters inside 30 Hudson Yards in Manhattan's West Side district, and at 230 Park Avenue South in Midtown Manhattan, both in New York City, respectively. Turner is known for several pioneering innovations in U.S. multichannel television, including its satellite uplink of local Atlanta independent station WTCG channel 17 as TBS—one of the first national "superstations", and its establishment of CNN—the first 24-hour news channel. It later launched a sister cable network, TNT, the children's channel Cartoon Network, and the movie channel Turner Classic Movies (TCM). Turner South—a network devoted to regional sports and southern lifestyle programming—was launched by Turner in 1999, but was later sold to Fox Sports Networks in 2006 to form SportSouth. The same year, it acquired Liberty Media's stake in their joint venture Court TV. On June 14, 2018, Time Warner, including Turner Broadcasting System, was acquired by telecom firm AT&T and re-branded WarnerMedia. After the purchase, "Turner" was phased out as a corporate brand, and on March 4, 2019, its properties were dispersed into either WarnerMedia Entertainment (TBS, TNT, and TruTV), WarnerMedia News & Sports (CNN, Turner Sports, and AT&T SportsNet), or brought directly under Warner Bros. (Cartoon Network, Adult Swim, and Turner Classic Movies). On August 10, 2020, the WarnerMedia Entertainment and Warner Bros. Entertainment assets were merged to form WarnerMedia Studios & Networks Group. As of 2020, AT&T reported the financial results for WarnerMedia's ad-supported cable networks under the Turner business unit, while also using the term "the TNets" to refer to the group of TBS, TNT, and TruTV in press releases. On April 8, 2022, WarnerMedia merged with Discovery, Inc. to form Warner Bros. Discovery, and almost all of both companies' ad-supported cable networks were brought under the unit Warner Bros. Discovery U.S. Networks (though Turner International remained as the international company website until 2022 (due to result of the Warner Bros. Discovery merger).
