Summary
While binge-watching an entire series can typically be done in a couple of long nights or weekends, watching the whole gamut ofNCISshows would take much longer than that.The originalNCISseries has been on air since 2003 and has 21 seasons. In season 21, the franchise celebrated the1000th episode ofNCISbetween the flagship and its spinoff series. The 1000NCISepisodes compriseNCIS, NCIS: Los Angeles, NCIS: New Orleans, NCIS: Hawai’i,andNCIS: Sydney.With so many shows to watch, fully experiencing the franchise is a serious investment.
It would take a long time to watch all 1000 episodes (and counting) of theNCISfranchise, and it’s about to get even trickier with the introduction of two new series that will expand thesharedNCISuniverseeven further.NCIS: OriginsandNCIS: Tony & Zivawill add more episodes to theNCISroster, telling the stories of core Major Case Response Team members Jethro Gibbs, Ziva David (Cote de Pablo), and Anthony DiNozzo (Michael Weatherly). The characters hail from the main series, which had released 467 episodes ahead ofNCISseason 22.

All 8 Spinoffs In The NCIS Franchise Explained
NCIS has evolved into a massive franchise with 8 spinoffs to explore. Their key differences make for distinct viewing experiences and characters.
It Would Take Around 30 Days To Watch All Of The NCIS Universe
Binge-Watching NCIS Would Take One Month
To binge-watch the entire NCIS universe, the avid viewer would need 42,936 minutesand 47 seconds to spare. In other words, that’s over 715 hours (or between 29 and 30 days). If a person wanted to have anNCISmarathon, watchingNCIS, NCIS: Los Angeles, NCIS: New Orleans, NCIS: Hawai’i,andNCIS: Sydneyfrom start to finish without taking any breaks, they would need to watch for a whole month straight. A good starting point could be getting familiar with the franchise throughNCIS: Sydney,the only series that can be comfortably watched in a day or so.
20,114 minutes, 4 seconds

13,800 minutes, 36 seconds
6,381 minutes, 46 seconds

2,294 minutes, 20 seconds
NCIS: Sydney
346 minutes, 1 second
While getting to know Gibbs, Tony, Ducky, and the rest of the MCRT on a deeper level is intriguing, catching up with the Washington D.C. team alone would take 335 hours or about 13 days. If a person wanted to brief themselves from the time that Leroy Gibbs boarded Air Force One inNCISseason 1, episode 1, “Yankee White,” totheNCISseason 21 finale, they would need to take about two uninterrupted weeks to do so. Having so muchNCISuniverse to explore is exciting, but there is only so much time in a day.
How Long It Would Take To Watch The Main NCIS Show At A Realistic Speed
Watching NCIS Would Realistically Take Two Years
It’s understandable not to have a whole month to dedicate toNCIS,and that would be without sleeping or taking any breaks. If a person wanted to experienceNCISat a realistic speed, watching the entire franchise whileviewing about an average of an hour ofNCISdaily would take almost two years. By then, another season of the flagship series could have been released, adding to the load. That’s in addition to new seasons fromNCIS: Origins, Tony & Ziva,andSydney,which will continue to expand theNCIStimeline, respectively.
