Blue Screen of Death

From TeeVeePedia, the Internet TV Encyclopedia.

The Blue Screen of Death is a legendary phenomenon that most scientists claim doesn't actually exist. According to myth, if a television network cancels its entire lineup at the same time and doesn't replace any of the cancelled shows, their transmitter will begin broadcasting the Blue Screen of Death. This will cause other networks to disappear one by one, until at last all of television is consumed. This will signal God to begin Armageddon and the Last Judgment.

A similar phenomenon is believed to occur in computers, although so far this hasn't been seen yet.
