The series was created by Donald P. Bellisario and Don McGill as a backdoor pilot with the season eight episodes "Ice Queen" and "Meltdown" of JAG. The series premiered on September 23, 2003 featuring an ensemble cast which has included Mark Harmon, Sasha Alexander, Michael Weatherly, Cote de Pablo, Pauley Perrette, Sean Murray, Wilmer Valderrama, Jennifer Esposito, Emily Wickersham, Brian Dietzen, Duane Henry, Lauren Holly, Rocky Carroll, and David McCallum.
Senior Special Agent Leroy Jethro Gibbs (Mark Harmon) was born in Stillwater, Pennsylvania to Jackson and Ann Gibbs. He enlisted in the Marine Corps in 1976 and became a Scout Sniper. After serving tours of duty in Panama and Iraq, he retired from the Marine Corps with the rank of Gunnery Sergeant. He joined NIS, which later became NCIS, after his wife Shannon and only daughter Kelly were murdered in 1991. He later traveled to Mexico and murdered the drug dealer responsible, a crime he kept concealed for twenty years. Since then, he has been married and divorced three times, and is single, although he has had a number of romantic relationships since his last divorce.
