PASADENA, Calif. (AP) -- "The Voice" is a ratings success for NBC, but judge Cee Lo Green says it has one more mountain to climb.
Green said Friday that "The Voice" has yet to mint a new music star from its contestants, and he'd like to be a part of changing that.
As a contrast, Fox's "American Idol" has developed stars like Kelly Clarkson and Carrie Underwood.
Green has alternated with Usher as a judge on "The Voice." He says he'd like to continue but he has other ambitions that might someday pull him away.
Green is starring in a TBS comedy series with his colleagues in the rap group Goodie Mob that is due to air later this year.
