CSI: Crime Scene Investigation
The series follows Las Vegas criminalists working for the Las Vegas Police Department as they use physical evidence to solve grisly murders in this unusually graphic drama, which has inspired a host of other cop-show "procedurals". The series mixes deduction, gritty subject matter and character-driven drama. The network later added spin-offs CSI: Miami and CSI: NY, which have both been cancelled after ten and nine seasons respectively.
