CBS cancels ‘CSI,’ will air Two-Hour Movie Finale

CBS has officially cancelled "CSI: Crime Scene Investigation" after 15 seasons. The network announced that the crime drama will end with a two-hour movie finale on Sept. 27.

Joe Adalian with Vulture was the first to report on the news last week.

According to Variety, the finale will reunite the show's original stars William Petersen and Marg Helgenberger. Other cast members will also reportedly return for the last episode.

"It's easy to take it for granted," said Kelly Kahl, CBS senior executive VP. "This is one of the strongest and longest-running dramas in TV history. This was one of the shows that reversed our fortunes and put us in the right direction."

"CSI" is the second long-running show to get canceled so far. FOX recently ended "American Idol."

Entertainment Weekly wrote, "In the weeks running up to the announcement. CSI was considered likely to score some kind of renewal despite struggling mightily in the ratings this year. The show averaged 11.2 million viewers and a 2.1 rating among adults 18-49 (including seven days of DVR playback). Those numbers could have been potentially survivable for a freshman series, but shows tend to get more expensive to produce as they age."

"CSI's" Ted Danson will reportedly head to the spinoff show, "CSI: Cyber," which was just renewed. He will star opposite Patricia Arquette.

"CSI" was not the only show to get canned by CBS. CBS also canceled "The Millers," "Battle Creek," "Stalker" and "The McCarthys."

The network renewed "2 Broke Girl," "The Big Bang Theory," "Madam Secretary," "Mom," "Mike & Molly," "NCIS: NOLA," "Scorpion," "Survivor," "NCIS," "The Good Wife," "Criminal Minds," "Blue Bloods," "Hawaii Five-0," "NCIS: Los Angeles," "Elementary," "Person of Interest," "The Odd Couple," "The Amazing Race," "The Undercover Boss," "60 Minutes" and "48 Hours."
