The Year 2000 problem (also known as the Y2K problem, the millennium bug, Y2K Bug, and Y2K) was a computer problem that affected lots of computer systems. 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). This meant that the computer could confuse the year 2000 with the year 1900, because both would be written as 00. 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 to avoid the bug. The preparation for Y2K had a significant effect on the computer industry. No big computer failures occurred when the year changed to 2000.

+The '''Year 2000 problem''' (also known as the '''Y2K problem''', the '''millennium bug''', '''Y2K Bug''', and '''Y2K''') was a computer problem that affected lots of computer systems. It happened because of the way in which some early [[computer program]]s were made to handle only years containing two digits (for example '92 instead of 1992). This meant that the computer could confuse the year 2000 with the year 1900, because both would be written as 00.

People were panicked by press coverage and media speculation, as well as corporate and government reports.

-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 program]]s 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 a big concern that very important [[industry|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 significant 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.
-Then everyone was like.. AHHHH! then nothing happened. the end.
