The first television series to feature the characters was The Alvin Show. The cartoon gave more distinctive looks and personalities to the three chipmunks than just their voices, and an animated portrayal of Seville was a reasonable caricature of Bagdasarian himself. The series ran from 1961 to 1962, and was one of a small number of animated series to be shown in prime time on CBS. Unfortunately, it was never an immediate success in prime time and was canceled after one season, only to find new life in syndication.
In addition to Alvin cartoons, the series also featured the scientist Clyde Crashcup and his assistant Leonardo. Those characters did not feature prominently on any of the later series. Crashcup made a single cameo appearance in A Chipmunk Christmas, and in an episode of Alvin and the Chipmunks. The television series was produced by Format Films for Bagdasarian Film Corporation. Although the series was broadcast in black and white, it was produced and later re-run in color. 26 episodes each were produced for the Alvin and the Chipmunks and Clyde Crashcup segments, along with 52 musical segments.
