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. TBS originated as WTCG, a UHF terrestrial television station in Atlanta, Georgia. 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. TBS is a national cable and satellite channel, available throughout the entire United States. Until October 1, 2007, the national TBS feed could not be viewed within its home media market of the Atlanta metropolitan area, due to the over-the-air presence of WTBS, which carried a nearly identical schedule, plus the required public affairs programming and E/I programming for children.
