Year 2000 problem
The Year 2000 problem (also known as the Y2K problem, the millennium bug, Y2K Bug, and Y2K) was a problem. It happened because of the way in which some early computer programs were made to handle only years containing two digits (for example '92 instead of 1992). 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. People were panicked by press coverage and 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 this had a significant effect on the computer industry. No big computer failures occurred when the year changed to 2000.
