In the old days, before film and radio, in the age of authenticity, people read
novels and witnessed how the protagonists shaped their personalities—how they
became unique and autonomous individuals. This genre was called Bildungsroman: a
novel (Roman) depicting the building (Bildung) of an authentic self. Readers
learned from these media how to build themselves in the same way.
When watching, and participating in an Idol show, we also see how a personality
is built: At the outset, all competitors are unknown, average people. They have
a very low profile. At the end, at least the winners have become high-profile
idols. The essence of the show is not simply to depict, but, much more
intensely, as true reality TV, to actually be the life path by which a person
becomes who they are.
The old Bildungsroman, was a fantasy about self-building, whereas Idol is the
real—or better— wink, wink—hyperreal deal.
