Cartoon Network (CN) is an American cable television network owned by Turner Broadcasting which airs animated programming. The channel was launched on October 1, 1992, after Turner purchased the animation studio Hanna-Barbera Productions in 1991. It was originally a 24-hour outlet for classic animation properties from the Turner Broadcasting libraries and was all-ages-oriented, but now the channel targets children and teens (about ages 8–15) with mature content during its late night daypart Adult Swim, which is treated as a separate entity for promotional and ratings purposes. The network broadcasts shows ranging from action to animated comedy. Original series started in 1994 with Space Ghost Coast to Coast, along with Cartoon Cartoons original programs like Dexter's Laboratory, Cow and Chicken, I Am Weasel, The Powerpuff Girls, Ed, Edd n Eddy, Johnny Bravo, and Courage the Cowardly Dog. In 2009, it started airing live-action programming, including movies from Warner Bros. and New Line Cinema. The network celebrated its 20th birthday; this celebration started on October 1, 2012, and ended on November 4, 2012.
