The Year 2000 problem (also known as the Y2K problem, the millennium bug, and the Y2K Bug) was the result of a practice in early computer program design that caused some date-related processing to operate incorrectly for dates and times on and after January 1, 2000. It caused widespread concern that critical industries (such as electricity or finance) and government functions would cease operating at exactly midnight, January 1, 2000, and on other critical dates which were billed as "event horizons". This fear was fueled by the attendant press coverage and other media speculation, as well as corporate and government reports. People who understand how computers work recognized that finely tuned systems could get "confused" when the 97, 98, 99, ?? ascending numbering assumption suddenly became invalid. Companies and organizations world-wide checked and upgraded their computer systems. The preparation for Y2K thus had a significant effect on the computer industry. No significant computer failures occurred when the clocks rolled over into 2000. Debate continues on whether the absence of computer failures was the result of the preparation undertaken or whether the significance of the problem had been overstated.
