This is the theme song for the CBS TV series CSI
, which went on the air in 2000 (although when the huge "YEAAAHHH!!!!" is heard it's actually from "Won't Get Fooled Again," also by the Who, which was is spliced in). The song is an appropriate choice, as the crime scene investigators try to determine "who" the victims are and "who" killed them. Fans of the The Who also fit the demographics of the show, which is targeted to baby boomers.
When CBS created spin-off shows, they used more Who songs: CSI Miami
(2002) uses "Won't Get Fooled Again
"; CSI New York
(2004) uses "Baba O'Riley
"; CSI: Cyber
(2015) uses "I Can See For Miles
The Who and CBS have gotten along quite well, as the shows enjoyed stellar ratings and the group has profited from the use of the songs.
