JAG (U.S. military acronym for Judge Advocate General) is an American legal drama television show with a distinct U.S. Navy theme, created by Donald P. Bellisario, and produced by Belisarius Productions in association with Paramount Network Television (now CBS Television Studios). This series was originally aired on NBC for one season from September 23, 1995, to May 22, 1996, and then on CBS for an additional nine seasons from January 3, 1997, to April 29, 2005. The first season was co-produced with NBC Productions, and was originally perceived as a Top Gun meets A Few Good Men hybrid series.
In the spring of 1996, NBC announced that the series had been canceled after finishing 79th in the ratings, leaving one episode unaired. In December 1996, the rival network CBS announced it had picked up the series for a midseason replacement original 15 completed episodes from its second season. For several seasons, JAG climbed in the ratings and was on the air for nine additional seasons. JAG furthermore spawned the hit series NCIS, which in turn led to spin-offs NCIS: Los Angeles and NCIS: New Orleans.
In total, 227 episodes were produced over 10 seasons. At the time of the original airing of its fifth season in the United States, JAG was seen in over 90 countries worldwide. JAG entered syndication in early 1999.
