TBS (originally an initialism of Turner Broadcasting System) is an American basic cable television network owned by the Global Linear Networks division of Warner Bros. Discovery. It carries a variety of programming, with a focus on comedy, along with some sports events through TNT Sports, including Major League Baseball, Stanley Cup playoffs, and the NCAA men's basketball tournament. As of September 2018, TBS was received by approximately 90.391 million households that subscribe to a pay television service throughout the United States. By June 2023, this number has dropped to 71.3 million households. TBS' sister networks are TNT, TruTV, and Turner Classic Movies, with the first two channels also providing sports coverage through TNT Sports.
TBS was originally established on December 17, 1976, as the national feed of Turner's Atlanta, Georgia, independent television station, WTCG. The decision to begin offering WTCG via satellite transmission to cable and satellite subscribers throughout the United States expanded the small station into the first nationally distributed "superstation". With the assignment of WTBS as the broadcast station's callsign in 1979, the national feed became known as SuperStation WTBS, and later SuperStation TBS, TBS Superstation, or simply TBS. The channel broadcast a variety of programming during this era, including films, syndicated series, and sports (including Atlanta Braves baseball, basketball games involving the Atlanta Hawks and other NBA teams, and professional wrestling including Georgia Championship Wrestling, Jim Crockett Promotions, World Championship Wrestling and All Elite Wrestling).
