CSI stands for Crime Scene Investigation. The original series (just called CSI: Crime Scene Investigation) is set in Las Vegas. The first spin off is CSI: Miami, and CSI:NY is just on it's first series. It's really interesting - the teams investigate murders by looking at the forensic evidence etc. William Petersen is in the first one, David Caruso in the second one, and Gary Sinise (one of my favourite actors) is in the third one. They are shown on Five, CSI:NY is on on a Saturday night, so I usually end up recording it.
