Context & Background
Since its television debut in 2003 as a spin-off of JAG, the flagship NCIS series has evolved into one of the longest-running scripted primetime shows in American television history. The series underwent its most significant transition during Season 19 when long-time lead Mark Harmon (Special Agent Leroy Jethro Gibbs) departed, passing the torch to Gary Cole as Special Agent Alden Parker.
The transition proved highly successful, sustaining strong ratings and allowing the series to cross the historic Season 23 finish line in May 2026. The franchise's enduring popularity relies heavily on its formula of character-driven drama, procedural mystery, and military culture. By maintaining a reliable schedule, CBS has cemented the show as a multi-generational viewing staple.
