Netflix will remove seasons 18 and 19 of the procedural drama NCIS from its streaming library on October 1, 2026. This move follows a licensing agreement with Paramount that requires the removal of older seasons as new ones are added.
Why it matters
Licensing agreements dictate the availability of long-running series on various platforms, often leading to the periodic rotation of content. This mechanism ensures that while some seasons disappear from Netflix, the entire catalog remains accessible on the studio's own platform, Paramount+.
Paramount+ currently hosts 23 full seasons of NCIS, while Netflix continues to adjust its library inventory. The removal involves seasons 18 and 19, the latter of which features the final appearance of Mark Harmon as Gibbs in episode 4.
The players
Netflix
Netflix is a global streaming service that manages a large library of licensed and original television content.
Paramount+
Paramount+ is a subscription video-on-demand service owned by Paramount Global that serves as the primary home for its studio's intellectual property.
Mark Harmon
Mark Harmon is a prominent actor known for his long-running lead role as Special Agent Leroy Jethro Gibbs on NCIS.
CBS
CBS is a major American commercial broadcast television network that produces and airs the NCIS series.
The details
Netflix periodically updates its NCIS offerings by pulling older content under its contract with Paramount. While seasons 1 through 5 were previously reintegrated in January 2025, the platform is now scheduled to drop the more recent installments to make room for incoming content.
Timeline
June 2024: Netflix removed the first 11 seasons of NCIS.
January 2025: Netflix reintegrated seasons 1 through 5 of the series.
October 1, 2026: Netflix will remove NCIS seasons 18 and 19.
October 6, 2026: NCIS Season 24 is scheduled to premiere on CBS.
Industry Dynamics
This rotation reflects the ongoing strategy of the streaming wars, where studios leverage their own platforms to maintain exclusive rights to legacy hits. By controlling the distribution flow, major studios ensure that subscribers are funneled toward their dedicated streaming services.
Viewers currently watching seasons 18 and 19 on Netflix will need to finish the episodes before the October 2026 deadline to ensure they do not lose progress. After this date, the complete archive of all 23 seasons will remain available for streaming on Paramount+.
The takeaway
Licensing agreements are constantly reshuffling content across streaming platforms, making long-term access unpredictable. For fans of long-running series, sticking with a primary studio-owned platform is often the only way to ensure uninterrupted access to the full catalog.
What happens next
NCIS Season 24 is scheduled to premiere on CBS on October 6, 2026.
