The phenomenon appeared in the early 1970s. It was thanks to the popularity of young French actress Sylvie Vartan and the movie she played in called "Cherchez l'idole" ("Look for the Idol"). The movie came out in Japan in November 1964 under the title "Aidoru o Sagase". The term "idol" started being used for girls, mostly between 14 and 16, who were just beginning their path to stardom or for very young new stars.
