As the year 2000 approached, governments and businesses faced an unusual computer problem. Many older systems stored years using only two digits instead of four to save storage space.
This meant that 1999 was stored as "99." When the year changed, 2000 was supposed to be represented by the number "00."
Some programs could interpret "00" as the year 1900 instead of 2000, which could lead to errors in date calculations, financial records, expiration dates, and other systems that relied on accurate dates.
Solving this problem took years of work. Businesses and governments had to identify vulnerable systems, rewrite software, replace outdated hardware, and repeatedly test their systems before January 1, 2000.
These efforts cost enormous sums of money. Although estimates varied, Gartner predicted that the cost of addressing software problems worldwide would reach between $300 billion and $600 billion, while businesses and government agencies in the United States were expected to spend around $100 billion.
