Turner Broadcasting System, Inc. was an American television and media conglomerate founded by Ted Turner in 1965. Based in Atlanta, Georgia, it merged with Time Warner (later WarnerMedia) on October 10, 1996. As of April 2022, all of its assets were absorbed into Warner Bros. Discovery (WBD). The headquarters of Turner's properties were largely located at the CNN Center in Downtown Atlanta, and the Turner Broadcasting campus off Techwood Drive in Midtown Atlanta, which also houses Techwood Studios. Some of their operations were 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 was 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 the Cable News Network (CNN)—the first 24-hour news channel. It later launched a sister cable network, TNT; the professional wrestling promotion World Championship Wrestling (WCW), the animation-centered Cartoon Network (which later spawned an adult-oriented night-time sister network in the form of Adult Swim, as well as the classic-cartoon channel Boomerang), and the classic-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. WCW assets were later sold to the World Wrestling Federation (WWF, now WWE) in 2001.
