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". CSI has been the number one scripted series in the Neilsen ratings for three years running.
This show is based on the box office film in 1998 'The Net'. After Angela Bennett a computer expert opens an unexpected email she is then thrown in to a world of terrorism, drugs, and money. The terrorists are called the praetorians, everything they do is build around the computer age.
