JAG is an American legal drama television show with a distinct military theme, created by Donald P. Bellisario, and produced by Belisarius Productions in association with Paramount Network Television (now CBS Television Studios). The first season was co-produced with NBC Productions.
Originally conceived as a Top Gun meets A Few Good Men, the pilot episode of JAG first aired on NBC on September 23, 1995, but the series was later cancelled on May 22, 1996, after finishing 79th in the ratings, leaving one episode unaired. Rival network CBS picked up the series for a midseason replacement, beginning on January 3, 1997. 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 spun off another fake-NCIS series and NCIS: New Orleans. JAG is also loosely connected to NCIS: New Orleans as Zoe McLellan acted in both series, but as different characters. Similarly, Dean Stockwell acted in JAG and appeared the in NCIS: New Orleans episode Chasing Ghosts as a different character.
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
