Year 2000 problem
The English used in this article or section may not be easy for everybody to understand. (December 2011)
The Year 2000 problem (also known as the Y2K problem, the millennium bug, Y2K Bug, and Y2K) was a problem that happened because of the way in which some early computer programs were made. They were made to handle only years containing 2 digits (for example '92 instead of 1992), and people started fearing that date-related processing would happen incorrectly for dates and times after December 31 1999. It caused concerns that many industries (such as electricity or financial) and government functions would stop working at exactly midnight, January 1 2000, and on other critical dates which were called "event horizons". More people were panicked by press coverage and other media speculation, as well as corporate and government reports. Companies and organisations around the world had to check and upgrade their computer systems. The preparation for Y2K thus had a significant effect on the computer industry. No massive computer failures occurred when the year changed to 2000. Debate continues on whether the absence of computer failures was the result of the preparation undertaken or whether the problem had been overstated.
