CSI: Crime Scene Investigation (also known as CSI) is an American crime drama television series, which premiered on CBS on October 6, 2000. The show was created by Anthony E. Zuiker and produced by Jerry Bruckheimer. It is filmed primarily at Universal Studios in Universal City, California.
The series follows Las Vegas criminalists as they use physical evidence to solve grisly murders in this unusually graphic drama, which has inspired a host of other cop-show "procedurals". An immediate ratings smash for CBS, the series mixes deduction, gritty subject matter and popular characters. The network quickly capitalized on its hit with spin-offs CSI: Miami and CSI: NY, and renewed CSI for an eleventh season on May 19, 2010.
CSI has been recognized as the most popular dramatic series internationally by the Festival de Télévision de Monte-Carlo, which has awarded it the "International Television Audience Award (Best Television Drama Series)" three times. CSI's worldwide audience was estimated to be over 73.8 million viewers in 2009.
