CSI: Crime Scene Investigation is a multi-media franchise that began with the self-titled original series developed by Anthony E. Zuiker. The series follows various detectives as part of the CSI teams as they work behind the scenes (and in the field) to uncover the truths behind unsolved murders. The series has also enjoyed an extensive collection of simulation-style video games over the years as companions to ongoing television shows.
