Equally important to the group's commercial success is the group's image, carefully controlled by managing all aspects of the group's dress, promotional materials (which are supplied to teen magazines), and video clips. Typically, each member of the group will have some distinguishing feature and be portrayed as having a particular personality stereotype - such as "the baby", "the bad boy", "the nice boy" - whilst managing the portrayal of popular musicians is as old as popular music, the particular pigeonholing of boy band members is a defining characteristic of boy and girl bands.
The commercial success of specific boy bands does not tend to last long. As the fans (mostly preteen girls) of boy bands age, their musical tastes evolve and they seek something different. If success is sustained, often one or more members of the band will leave and seek a solo career (particularly if they have some songwriting ability), though few manage sustained solo success.
Famous boy bands:
In South Park, Cartman formed a boy band named Fingerbang[?]. In The Simpsons, Bart is recruited to a boy band named Party Posse[?] that is secretly a vehicle for subliminal army recruitment messages.
