1. Sensationalism for the gratification of a gawking public; gratuitous saturation. Glitterporn is the media equivalent of driving past an accident and being unable to look away.
2. Media coverage of celebrities down to the last mundane detail of their lives.
Examples include media coverage of celebrities ala Tabloid TV, the Scott Peterson murder trial, and the Washingtonienne sex scandal.
As I watch Entertainment Tonight's coverage of Britany Spears's recent knee injury, I asked myself, "Why do I watch this glitterporn when I could be living my own life?"
