Y2K Nostalgia: See historical photos of new millennium panic before the year 2000
Updated Dec. 18, 2024, 3:38 p.m. ET

According to the National Museum of American History, “the term Year 2000 bug, also known as the millennium bug and abbreviated as Y2K, referred to potential computer problems which might have resulted when dates used in computer systems moved from the year 1999 to the year 2000.” In an effort to save space, earlier electronic computers “abbreviated the four-digit year designation and stored only the final two digits," according to the museum. “The fear was that when clocks struck midnight on January 1, 2000, affected computer systems, unsure of the year, would fail to operate and cause massive power outages, transportation systems to shut down, and banks to close. Widespread chaos would ensue.” “Research firm Gartner estimated the cost of Y2K remediation to be $300 - $600 billion. Businesses and government organizations created special technology teams to ensure that all hardware and software was Y2K compliant (Y2KC).” In this file photo, Sam and Ria Skemp and the pet Chihuahua, Rattel, celebrate the New Year on Dec. 31, 1999, at home with party and all of the things they bought for Y2K, including gas masks.
