MySpace. YouTube. Facebook. Friendster. Nearly every teen in America is on the Internet every day, socializing with friends and strangers alike, "trying on" identities, and building a virtual profile of themselves - one that many kids insist is a more honest depiction of who they really are than the person they portray at home or in school.

In "Growing Up Online," Frontline peers inside the world of this cyber-savvy generation through the eyes of teens and their parents, who often find themselves on opposite sides of a new digital divide. A generation with a radically different notion of privacy and personal space, today's adolescents are grappling with issues their parents never had to deal with: from cyber bullying to instant "Internet fame," to the specter of online sexual predators.

Frontline producer Rachel Dretzin investigates the risks, realities, and misconceptions of teenage self-expression on the World Wide Web.
