died in 1972, his son Ross Jr. revived Alvin, Simon, and Theodore in 1979 on Saturday mornings, and on the 1980 album Chipmunk Punk. The series became more popular than it had been in the '60s, and albums of the Chipmunks singing country, Christmas, rock, and Hollywood favorites were big sellers, though they didn't enjoy chart success. Although the cartoon was no longer in production by the '90s, new Chipmunks records continued appearing, among them 1998's A-Files: Alien Songs.
In 2007, a film series debuted with Alvin & the Chipmunks -- the first being so successful that it spawned three sequels: 2009's Alvin and the Chipmunks: The Squeakquel, 2011's Alvin & the Chipmunks: Chipwrecked, and 2015's Alvin & the Chipmunks: The Road Chip. A CGI-animated TV series, ALVINNN!!! and the Chipmunks, premiered on Nickelodeon in mid-2015. The accompanying soundtrack -- We're the Chipmunks -- contained all-original material performed by Alvin, Simon, and Theodore, as well as their female counterparts, the Chipettes. In addition to a revamping of the main title theme, the soundtrack also included songs "Ooh Girl" and "Ring-A-Ding." ~ John Bush
