CSI: Crime Scene Investigation (commonly referred to as CSI or CSI: Las Vegas) is a popular, Emmy Award-winning CBS television series that trails the investigations of a team of Las Vegas forensic scientists as they unveil the circumstances behind mysterious and unusual deaths and crimes committed. First aired in October 2000, the show has since spawned two spinoffs, each enjoying their own success. The first spin-off, which debuted in September 2002, is set in Miami (CSI: Miami) and the show's second is set in New York City (CSI: NY) debuted in September 2004.
CSI: Miami is a spin-off of the popular CBS network series CSI: Crime Scene Investigation. Like the original CSI, CSI: Miami is a police procedural about a team of forensic scientists who serve the Miami-Dade Police Department. It is set in present-day Miami-Dade County (which mainly includes unincorporated Miami-Dade, as well as Miami, Kendall, Miami Beach, Coral Gables, Opa-Locka, Key Biscayne, etc.).
It is filmed primarily in the United States, mostly in the Los Angeles area (due to cheaper production/studio costs) and of course, all around the South Florida/Miami-Dade area. The series has been exported to over a dozen countries worldwide. The show averages 20 million viewers an episode, making it Monday's highest-rated series and one of the most watched shows in North America. In 2006, Reuters reported that the show is "the most-watched U.S. series around the world".
CSI: NY is an American police procedural television series which premiered on September 22, 2004. The series was the second spinoff from CSI: Crime Scene Investigation and was introduced during an episode of CSI: Miami when Horatio Caine journeyed to New York City in pursuit of a murder suspect who fled Miami. It is much bloodier than the Miami version, and was filmed in a hard blue light until Season 2, when CBS President Les Moonves wanted to make the show appear "less cold".
Another crossover between NY and Miami was featured on November 7, 2005 (CSI: Miami), and November 9, 2005 (CSI: NY), which involved a crashed plane and an escaped serial killer, and included members of both casts. Episode 322, "Cold Reveal", which aired May 9, 2007, featured a crossover between the series and Philadelphia-based police procedural Cold Case.
Like the other two CSI programs, the theme song is by The Who; this time the song is "Baba O'Riley", often incorrectly known as "Teenage Wasteland". Anthony E. Zuiker had wanted The Who's "Behind Blue Eyes" to be the show's theme song, but CBS president Leslie Moonves turned it down in favor of "Baba O'Riley."[1]
