Because from the 1950's to the 1980's, in an almost universal practice, computer software programmers used just two digits to identify a year when writing software code. It made sense then, and it made their job easier. The reality , however, is that while technological improvements have occurred, many computer programs have not been rewritten. And the truly unfortunate reality is that the doomsday talk in the press is probably true. But most technology experts agree the problem is real , will have unexpected and undesirable consequences , and may be much graver than anyone has yet realized .
Most businesses rely on one, or a variety, of computer systems for their daily operation.
This reliance usually extends to the computer systems of the business' suppliers that provide essential goods, services and information. Some businesses have already begun the process of ensuring that their computer systems are End of Century compliant. This work can be carried out by using internal resources, outside consultants, or a combination of both. Some of these businesses will find that fixing the affected software may not be an option when the original code has been lost or a license to alter the software cannot be obtained from the software creator. Questions have arisen whether businesses that have purchased software that is not End of Century compliant will have any recourse against software vendors for damages relating to the End of Century problem.
