Includes all 398 episodes from 17 seasons on 100 discs; NCIS was originally a spin off from the TV series JAG. The show began airing on CBS in 2003. During season 1 the show was called Navy NCIS but was shortened to just NCIS before it aired for its second season. The show follows a group of investigators who work for the Naval Criminal. Crescent City: Part 1. When the body of a New Orleans politician and ex-NCIS agent washes ashore, the two field offices unite to uncover the motive and reveal the killer. Crescent City: Part 2. Gibbs and Special Agent Pride chase leads in New Orleans after evidence points to a copycat serial killer; Bishop sends DiNozzo a special souvenir.

The questions surrounding the future of NCIS are over.

The beloved CBS procedural has landed a renewal for Season 19, according to The Hollywood Reporter.

Additionally, it has been revealed that Mark Harmon will be back, months after reports suggested the actor would be saying goodbye to the series he has called home for 18 seasons.

There were reports that CBS could end the series without Harmon, meaning that the series would have wrapped with its current 18th season.

There is still a question surrounding Harmon's involvement, however. Without revealing what his role will be, fans will be left to question it until the announcement is made.

It is possible that the actor could be part-time, or we could be looking at a reduced episode order. CBS still has a lot of renewal and cancellation decisions to make, however.

Another possibility is that we could be approaching the end of NCIS as we know it.

CBS has already announced NCIS: New Orleans would be wrapping after seven seasons, and the jury is still out on whether NCIS: Los Angeles will be coming back.

It was recently reported that NCIS: Hawaii is nearing a series order, with the new take on the franchise to feature a female lead.

But CBS is largely staying quiet about what will become of the original NCIS. All we can do is speculate until we get that announcement.
