When NCIS first premiered more than two decades ago, few could have imagined the huge cultural impact it would go on to have. Now, as the series approaches its 500th episode, it stands as one of the longest-running and most successful crime dramas in television history.
Throughout the years, the show has gone through major cast changes and unforgettable storylines — including the shocking death of Special Agent Kate Todd. Despite the changes, the series has remained strong thanks to its winning formula: gripping investigations combined with deep, character-driven storytelling.
Today’s cast — including Gary Cole, Wilmer Valderrama, Sean Murray, and Katrina Law — continues to carry the legacy forward as the iconic CBS drama celebrates another historic milestone.
