Digital Nation

According to recent Kaiser Family Foundation data, American children aged 8 to 18 average more than 50 hours a week with digital media -- that's more than a full work week. Coming Feb. 2, 2010 to PBS, FRONTLINE's "Digital Nation" explores the implications of living in a world consumed by technology and the impact that this constant connectivity may have on future generations. In this segment from "Digital Nation," FRONTLINE correspondent Douglas Rushkoff travels to the edge of the digital frontier -- South Korea -- for a look at a country that's embraced the wired world more thoroughly than any place on Earth, and is now potentially facing a new public health crisis: internet addiction.
