Karaoke establishments around the country today are not just places for singing in a group — they are increasingly for watching films, holding children's parties or for solo-crooning sessions.

Karaoke operators are offering a slew of new services that leverage their private rooms and attract new customers as the industry is expected to shrink in the face of the nation's aging population.

Valic Co., which operates 175 Cote D'azur-branded karaoke houses nationwide, started an experimental service at some locations last September dubbed Cinekara, making available recently released films for their customers to watch.
