TBS (Turner Broadcasting System) is an American cable television channel owned by Time Warner. It shows a variety of programming, with a focus on comedy, along with some sports coverage, including Major League Baseball and portions of the NCAA Men's Division I Basketball Championship.

The "TCG" officially stood for Turner Communications Group, the forerunner to Turner Broadcasting System, but the station used "Watch This Channel Grow" as a promotional slogan.
