Unlike television personalities, idols are marketed for their image, attractiveness, and personalities.[22][2] An idol's main objective is to "sell dreams", offering fans a form escapism from the troubles of daily life.[3] As such, they are seen as role models to the public, and their personal lives and image can sometimes be tightly controlled by their talent agencies,[4] even though there are also agencies who focus on their idols' career without interfering in their private lives.
