Chipmunks is an animated music group created by Ross Bagdasarian, Sr. in 1958. The group consists of three singing animated anthropomorphized chipmunks: Alvin, the mischievous troublemaker, who quickly became the star of the group; Simon, the tall, bespectacled intellectual; and Theodore, the chubby, impressionable one. The trio is managed by their human father David Seville. In reality, David Seville was Bagdasarianâ€™s stage name, and the Chipmunks themselves are named after the executives of their original record label
In the 2007 CGI/live-action movie adaptation and its 2009 sequel, they were voiced in dialogue by Justin Long, Matthew Gray Gubler and Jesse McCartney, respectively. Bagdasarian, Jr. and Karman continue to perform the singing voices for Alvin, Theodore and the Chipettes, but Steve Vining now does Simonâ€™s singing voice. They are one of the successful music groups of all time, earning five Grammy awards, an American Music Award, a Golden Reel Award, a Kids Choice Award, and have been nominated for two Emmy awards.
