NCIS

NCIS, formerly known as NCIS: Naval Criminal Investigative Service, is an American police procedural drama television series revolving around a fictional team of special agents from the Naval Criminal Investigative Service, which conducts criminal investigations involving the U.S. Navy and Marine Corps. The concept and characters were initially introduced in a two-part episode in the eighth season of the CBS series JAG. The show, a spin-off from JAG, premiered on September 23, 2003 on CBS and, to date, has aired nine full seasons and has gone into syndicated reruns on USA Network, Cloo, and Ion Television. Donald Bellisario is co-creator, along with Don McGill, as well as executive producer. NCIS was originally referred to as Navy NCIS during season one; Navy was later dropped from the title as it was redundant. In season seven, NCIS was joined by a spin-off series, NCIS: Los Angeles, starring Chris O'Donnell and LL Cool J. In 2011, NCIS was voted America’s favorite television show. On March 14, 2012, CBS renewed NCIS for a 10th season scheduled to premiere on September 25, 2012. It was also reported Brian Dietzen will be promoted to series regular for season 10.
