CSI: Crime Scene Investigation, which premiered in 2000, and wrapped its 15th season on February 15, 2015, has officially been cancelled. Millions of fans across the globe mourn the loss of this innovative drama.

Upon its premiere 15 years ago CSI revolutionized the television industry, becoming one of the first crime based series to focus on forensic scientists and those who worked more “behind the scenes,” as opposed to the classic police officer or detective. This has inspired numerous similarly focused shows such as Bones, CSI spinoffs [Miami, New York, Cyber], and Criminal Minds, among others.

CSI has been criticized, as oftentimes the forensic scientists on the show do not specialize in one discipline and also conduct raids, interrogate criminals, and do other things that do not fall under their job descriptions. This has even influenced public perception of forensic sciences. The term “CSI effect” has been circulating since 2004, and refers to how the portrayal of the forensic sciences on CSI has increased awareness, interest, and general perception of forensic science.
CSI is also notable for having experienced several cast revamps throughout its long life, while still continuing to garner viewership. Only one original actor who appeared in the first episode remains, following the conclusion of season 15.

Although consistently drawing a large amount of viewers, and in earlier years holding a stable viewership, CSI has declined in ratings in the past few years.
While CSI will not be returning for a season 16, a 2 hour TV movie, in which original stars and fan favorites William Petersen and Marg Helgenberger will also appear, premieres on September 27, serving as a conclusion to the series. Ted Danson, who currently stars on CSI: Crime Scene Investigation, will also reprise his role, and appear in new seasons of CSI: Cyber.

Be sure to tune in to CBS on September 27!
