Ten years ago, IT departments and companies worked around the clock upgrading hardware and software to avoid the Y2K bug. I wasn't there, so I don't have first-hand knowledge of the work that went on, but I do know this: afterwards, when nothing happened, a lot of blame and finger-pointing went on. People were asked why the hell we spent so much money on such a fizzer. The problem is that, in this case, success looks like a total non-event, so it's hard to prove you saved the day.

PS - The threat was probably overstated in most cases.
PPS - But that doesn't mean 100% of the money spent was wasted.
