NCIS is an American police procedural television series that follows a fictional team of special agents from the Naval Criminal Investigative Service. The show blends elements of military drama and police procedural genres. The concept and characters were initially introduced in two episodes of the CBS series JAG (season eight, episodes 20 and 21: “Ice Queen” and “Meltdown”). A spin-off from JAG, the series premiered on September 23, 2003, on CBS. Since then, NCIS has completed twenty full seasons and is syndicated on the USA Network. The series was co-created and executive produced by Donald P. Bellisario and Don McGill.
