What's the correlation between idols and brainwashing? First I shall tell you my opinion about idols. For me, an idol is someone who appears in media and has beautiful appearance. Idols are usually seen with attractive expressions, poses, and clothings. Basically they are delicious for one's eyes. They seem to always be there for you, entertain you with their looks, voice, and talents.
One thing about them is that, even if you feel indifferent about them at first, if you see their pretty face very often, their charm will get you and you will love them. (Note: you must not hate their personality for this to happen though, and sometimes the charm can wear off). It is not difficult to find their gorgeous faces, especially on the Internet where you can download their digital pictures. Then you can view it anytime you want, or even set it as your desktop wallpaper.
Psychologically when a human often encounter another, a familiarity feeling will develop. It is not limited only in physical meetings....
