NCIS continues to dominate television, with 11 episodes making the top 100 telecasts of 2023. Despite strong contenders like the Super Bowl and other popular dramas, NCIS stands out. Noteworthy broadcasts include a three-show NCIS crossover and the debut of NCIS Hawaii. Season 21 is set to premiere with fresh episodes, coinciding with the launch of NCIS Hawaii. Unfortunately, David McCallum, known as Dr. Donald Mallard, passed away during the show’s hiatus, leading to a somber moment in the upcoming season. Fans can catch up on previous episodes, including the top 11, on Paramount Plus.
