The original CSI show that launched three spinoff series and accumulated numerous awards, including Golden Globes, first aired in 2000. Originally based on the acronym for Crime Scene Investigators working in Las Vegas, CSI follows a murder mystery of the week format, relying on a core team of specialists that changed throughout the run of the series. As one of the busiest crime labs in America, the series follows the investigators nights as they rely on technology and knowledge of criminal psychology to solve mysteries. Stars that have been regularly featured on the show range from Laurence Fishburne to Ted Danson and Marg Helgenberger to Elisabeth Shue.

Although the show aired its final episode on CBS in 2015, you can still watch CSI online, thanks to various legal streaming options.
