CSI is an innovative, new type of crime drama because the characters use cutting edge forensic tools to examine the evidence to solve the case. Rather than a 'whodunnit' cop show (investigating witnesses / suspects), CSI explores the 'howdunnit'. These top Las Vegas criminologists are challenged weekly to solve grisly murders in this unusually graphic (and hugely popular) drama. Methodical Gil Grissom heads the team, assisted by Catherine Willows.

CSI has been the number one scripted series in the Neilsen ratings for four years running. CSI is now in its 7th amazing season. An immediate ratings smash for CBS, the series adroitly mixes painstaking deduction, gritty subject matter and intriguing characters. The network quickly capitalized on its megahit with spin-offs `CSI: Miami' and `CSI: NY.'
