Fifteen seasons. Fifteen years. Talk about a good run. "CSI: Crime Scene Investigation" premiered back on October 6, 2000 and it's finally ending on September 27, 2015. It's not a shock to see the series end -- how long would you expect it to go on? -- but CBS made it official today, adding that the show will close with a two-hour TV movie starring OGs William Petersen and Marg Helgenberger. Season 15 already aired 18 episodes from September 2014 to February 2015, and the writing was on the wall when CBS cut the episode order by four. But at least they are giving the show a TV movie with the original cast, instead of just coldly announcing "You're canceled."

In more positive news, current "CSI" star Ted Danson will just move on over to the Patricia Arquette spinoff, "CSI: Cyber." So it's not like they're giving up on the franchise. But it's truly the end of an era to see the original modern crime procedural fade to black. This is the show that popularized forensic science as something cool, and darn near badass. And it's not too shabby to still earn more than 7 million viewers and a 1.1 rating after 15 seasons. Those were the Season 15 finale numbers, and that was without fans knowing for sure that this would be The End, so CBS can probably expect even better numbers for the 9/27 TV movie. Will you be tuning in for the big farewell?
