Non-event

A non-event is an anticipated or highly publicized event that does not occur or turns out to be anticlimactic or boring. Non-events are disappointing, as they are often much hyped prior to their occurrence.

Some notable non-events of recent history have been:

• The much-hyped 1973 appearance of Comet Kohoutek
• The 1986 appearance of Halley's Comet
• The live prime time special of Geraldo Rivera opening Al Capone's vault, which turned out to be empty
• The Y2K bug
