Disney's other phenomenally successful movie-musical/cross-marketing cash cow, the Cheetah Girls have evolved from their humble -- OK, totally auspicious -- beginnings as the protagonists of a best-selling series of young-adult books about an all-girl pop band. In 2003, the Disney Channel made the very wise decision to turn the stories of Galleria, Chanel, Aquanetta and Dorinda into a made-for-TV movie starring tween princesses Raven-Symone, Adrienne Bailon, Kiely Williams and Sabrina Bryan. Two more films (with a fourth promised in 2010), their incredibly lucrative soundtracks and a Christmas album followed. In 2006, the Cheetah Girls (sans Raven-Symone) went live, for real this time, becoming an actual touring act (opening for Vanessa Hudgens). In 2007, the trio released TCG, their first non-soundtrack, non-holiday studio album.
