It's pretty successful, so, unless the writers do something tragic to the long-term storyline or one of the prominent characters that meets with widespread hatred from their fans, I think they can keep going until they plan to quit and therefore plan a spectacular ending to the show.

NCIS can go on until they run out of good stories

I agree with becca85

NCIS can go forever if it has to as long as it keeps going as it is now I will keep on watching it until the time comes. NCIS will live on forever in my heart.

yer i agger parker89 ncis is the best and i will allways watch the repets

Picked two, but the show is doing incredibly well at the moment. So it could well be running for far more. Just hope NCIS isn't too affected by the cuts CBS has announced.

NCIS should never end ^^

I don't want it to be canceled cuz if there planed it then that means we can found out how it ened for our team if it got canceled then that means it would end at cliff hanger and we may never found out want happened.

I don't want it to end at all but we all know it will sooner or later. :(

i live in the uk and i watch it over here ! i started to watch half way thru the seasons but i brought them all on dvd just to catch up becuase the earlier seasons where pretty funny especially between Kate & tony and then they short of switched to Abby & McGee but for some reason the latest seasons like 6-7 have been a little bit boring :( ashamed to say becuase i love ncis theirs been a few good episode between 6-7 apart from that it been pretty good maybe their building up for the final season :( p.s it's not funny like it used to be but gotten more serious in the storylines as any one else notice this :( :( :( :( :(
