Y2K Bug: A Hoax Created Behind The Scenes?

On New Year’s eve, December 31, 1999, the world came to a standstill. Millions of people around the globe sat waiting for the long anticipated transition into a new millennium. The event they were anticipating was called Y2K, or “Year 2000.” This year was predicted to be a harbinger of an apocalypse of sorts. A minute into January 1, 2000… fear of a worldwide power loss… major economies would crash… jails would spring open to let out vicious criminals… money in banks would be spewing out of ATM machines… countries would grind to a halt as people would not understand what is happening… The end of the world would have come… No one would be sure what would happen next, but everyone would quickly learn that the very devices that made their lives easy would turn on them as those devices failed to process the shift into the new millennium.1

But then, when the end of the year 1999 did come, and all the time zones jumped into the new millennium, almost nothing of the sort happened. Planes did not fall out of the sky, jails did not let criminals free, and the world was certainly no closer to its end. What was it that left a planet of about six billion human inhabitants panic-stricken?2 The villain in this case was a bug programmed at the very roots of computers. Computer storage space was available at a premium at the dawn of the computer age in the 1960s. To economize in this aspect, programmers displayed dates in a two-digit format rather than the conventional four digit(YYYY) format. The programmers failed to factor in the imminent jump to a new millennium, or even a new century. The problem was quite simply that computers would be unable to process any year after the year 1999. The systems would be set back by a century. As the realization dawned upon the commercial sector in the early 1980s, there wasn’t much panic. However, as more specific problems began sprouting, the problem was recognized. This problem, famously dubbed as the Y2K Crisis or the Millennium Bug was the reason for the worldwide panic in the late 1990s.3

The Y2K problem began with the development of commercial computing. In 1957, Rear Admiral Grace Murray Hopper invented a programming language called FLOW-MATIC, the first to be coded in English in order to make computers easier for businesses to use. FLOW-MATIC formed the basis for the programming language COBOL, the acronym for “common business-oriented language.”4 The most commonly used data storage media was the eighty-column punch card. Due to the limited storage possible on these punch cards, COBOL used only 6 digits for dates. For example, January 4, 1987 would be stored as 010487 in the MMDDYY format. This shortcut seemed to be revolutionary at that time in terms of economizing on storage space, but little did they know that it would be the reason for a worldwide panic-induced frenzied-spending to correct this “bug.”

In a testimony by Alan Greenspan, ex-chairman of the Federal Reserve before the Senate Banking Committee, he said,

“I’m one of the culprits who created this problem. I used to write those programs back in the 1960s and 1970s, and was proud of the fact that I was able to squeeze a few elements of space out of my program by not having to put a 19 before the year. Back then, it was very important. We used to spend a lot of time running through various mathematical exercises before we started to write our programs so that they could be very clearly delimited with respect to space and the use of capacity. It never entered our minds that those programs would have lasted for more than a few years. As a consequence, they are very poorly documented. If I were to go back and look at some of the programs I wrote 30 years ago, I would have one terribly difficult time working my way through step-by-step.”5

After the development of COBOL in 1957, no one really bothered to think ahead to chart out possible problems. However, one of COBOL’s developers, Robert Bemer, along with a group of computer scientists, picked up this issue and attempted to warn against the use of the two digit-style and rather argued for the four-digit style for years. However, the hunger for businesses to increase their profits made the big businesses overlook this warning. To most businesses and governments, the year 2000 seemed much too far away to worry about. They thought they would cross that bridge when they get there, but little did they know that this very act of ignorance would create a bridge so large that crossing it would be impossible for many. Bemer again published warnings in the years 1971 and 1979, but they were ignored yet again. Another warning was issued by Peter de Jager, a Canadian computer engineer, who published an article titled “Doomsday 2000” that predicted an economic recession in the year 2000. However, by then, the warning signs were already visible for the world to see.6 Robert Bemer and Peter de Jager weren’t really the first to notice the problem. Programmers knew what their earlier compromise to economize now meant, and they began laying their bets on the hope that the erroneous code would be scrapped by the year 2000. However, the program was integrated into almost every essential sector you could think of. As the year 2000 got closer, the Y2K bug did seem to be very real.

Although realization of this potential problem hadn’t yet dawned upon much of humanity, the spending had already begun to correct the issue in time. One of the earliest high spenders was the New York Stock Exchange, having reportedly spent a figure close to $29 million and recruited about a 100 programmers to fix the bug.7 The leading nation in responding to the Y2K crisis was the United States. However, planning only began in the late 1990’s when it had become a subject of serious discussion. At last, the bridge was in sight and the governments and companies around the world began to plan their voyage across the millennium. The biggest leap was made by the United States, when President Clinton created the President’s Council on Year 2000 Conversion on February 4, 1998 by executive order 13073. This council was formed with the intention of addressing the broader picture regarding the impact of the year 2000 conversion in the United States and around the world. The council worked closely with small and large businesses alike to encourage greater Y2K preparation. Seeing these efforts, the United Kingdom and Australia followed suit by adopting similar programs. The UK formed two agencies, Action 2000 and Taskforce 2000, which were granted funding of $544 million, whereas the Australian Commonwealth’s spending was estimated to be around $12 billion.8 The United States alone spent $100 billion, including $8.5 billion by the federal government, according to the U.S. Department of Commerce. The worldwide bill was estimated at between $500 billion and $600 billion.9 Many people argued against spending on a such a large scale when the prognosis of the issue was still debatable. However, the Governor of Georgia, Roy Barnes, aptly said, “I don’t think you can overprepare for a disaster that could have happened. I’d rather err on the side of caution rather than on the side of recklessness.”10

As countries around the world were spending large amounts on the problem, panic began to grow as realization of the possible dire prognosis set in upon the people. As the year 2000 approached, panic was hitting a fever pitch. People began to stockpile on essential supplies, some governments couldn’t meet their deadline for Y2K compliances, and people all around the world were preparing for the worst. At the stroke of midnight, on New Year’s eve 1999 the world moved into the new millennium without skipping a beat. No system failures occurred except for a few minor issues that were quite comical. A 105 year old man was directed to kindergarten as his age showed up as five on the records. Some newborn children were registered as born on January 1, 1900.11 Defense Minister John Hamre said, “For a short period of time we were not able to process the information that the satellites were sending to us, but we’re operational now.” This was a rare case of admittance from the Pentagon as the ground station lost contact with a satellite. Another comical issue occurred when a video rental customer was sent a bill of around $91,000 for apparently having missed payment for the past 100 years.12 Another problem that arose, which demonstrated that the Y2K bug was truly global, occurred in France. Meteo France reported that the Y2K bug was responsible for an issue in the system on its website. Weather forecast for January 1, 2000 showed the date on its page as 01/01/19100.13 The world breathed a sigh of relief as the problems that showed up on January 1, 2000 were only minor and required small fixes. It looked as if the disaster that was feared had been averted.

Success very rarely comes without critics, and in this case the critics were angered over the amount spent correcting the Y2K bug. Letters flooded into the rooms of editors of business periodicals accusing the IT professionals of having inflated the danger of the issue to scare businesses into spending more than was necessary. However, they were missing the bigger picture here. The Y2K crisis called for the most effective joint response effort from the private and public sectors that the United States had ever seen, as well as extensive international cooperation. In addition to avoiding disaster, the preventative effort was highly beneficial to businesses as they learned how to conduct contingency planning for IT malfunctions. Others, especially small businesses, learned how to use computers effectively for the first time.14

In the aftermath of this conundrum, critics began to call the whole crisis a hoax. Some even went as far as to calling it a conspiracy theory. In reality, it was the consistent heroic efforts of computer scientists, companies, and governments all over the world that helped us cross the finish line. The Y2K Bug, was it really all just a hoax? No, it was the greatest success story of the generation.15

  1. Hello Mohammad,
    Great job on your writing and I congratulate you on your publication! I always knew Y2K existed, part due to my parents sharing stories, but thy pretty much knew it wasn’t going to be a “real” thing, let alone scare. I think computers were still very new to society, making it a very unknown thing of the future that even the late 90’s couldn’t uphold. Great job once again on your article! Great job!

  2. I still think this the funniest panic for an end of the world. I mean come on, the date being wrong for like a day or two isn’t going to destroy the world. It reminds me of that Mayan calendar business that was also blown out of proportion just because people from long ago that are dead didn’t have a date after a certain time didn’t mean the world was going to end. I mean they probably all died before they could continue. Anyways, a very good article and I hope to read more from you.

    1. Banking systems rely on the correct date to calculate interest rates all the time.

      Banks individually spent millions of dollars fixing their systems.

      That’s just one small example.

  3. Great work. While I knew about the Y2K, I never knew why people were scared, and this article does a great job of presenting the information one is looking for in a logical and sensical format. The notion of Y2K is something that I heard much about, however, never knew that actual problems had occurred after the scare.

  4. One of the fascinating things about history is how relatively small changes can have big impacts. This article serves to remind me of such a fact. Had the government not began its operation to resolve the Y2K bug when it did, we could be living in an entirely different age. Some of us might not have even been born. A very well written article as a whole.

  5. As I read this article, it reminded me of a conversation I had with my mom a while back about the year 2000. She said that all the computers had to switch from the year 1999 to 2000 and that it was chaotic and memorable. I never understood why. In my head, I was like, “well, doesn’t it just switch numbers, what’s the big deal?”. But now I realize how big of a deal it actually was. I really liked your article, and the magazine cover you put, it allowed us to see how companies reacted to the y2k bug or wanted people to react to it. I can tell that a lot of people were terrified of what could’ve happened like when you say, “worldwide power loss… major economies would crash… jails would spring open to let out vicious criminals… money in banks would be spewing out of ATM machines… countries would grind to a halt as people would not understand what is happening…”. I think computer technology, in general, is amazing, so it was interesting to see how they overcame this obstacle, millions of dollars later. I also wonder what would’ve happened if they hadn’t paid so much money to fix the bug. Would they still be as mad?

  6. This article was super interesting! I had not realized that part of the issue came from programmers only displaying dates in two-digit formats rather than four digits. I also think that the responses of people are really interesting like people were preparing for the end of the world or were anxious about a change coming. It is crazy how fear can spread so fast and cause historical events like this.
