Walker, Texas Ranger is an American television action crime drama series created by Leslie Greif and Paul Haggis, both starring Chuck Norris as a member of the Texas Ranger Division. The show aired on CBS in the spring of 1993, with the first season consisting of three pilot episodes. Eight full seasons followed with new episodes airing from September 25, 1993 to May 19, 2001 and reruns continuing on CBS until July 28, 2001. It was broadcast in over 100 countries, and has since spawned a made-for-television movie, entitled Trial By Fire. The movie ended on a cliffhanger, which, as of 2013, has not yet been resolved. DVD sets of all seasons have been released. At various times since 1997, reruns of the show have aired, in syndication, on the USA Network and Action in Canada. As of September 13, 2010, the series is shown on WGN America.The show was known for its moral values. For example, the characters refrained from the use of drugs, and they participated in community service. Martial arts were displayed prominently as the primary tool of law enforcement and occasionally as a tool for Walker and company to reach out to the community. The show has since become one of the most popular action shows in television history and has gained a cult following for its camp appeal.
