Note: Y2K was an issue. There were few problems not because it was hyped or overestimated, but because business spent about $100 billion to fix potential software problems beforehand. It's really a great success story, but some people insist on saying it was all a hoax or unnecessary alarmism. Instead it was healthy alarmism, with a potential disaster avoided by a lot of hard work.
Added: I don't know why there was a jump step circa 1980. It doesn't necessarily represent anything social; it might have been some change in the amount of cash banks were required to keep on hand. Anyone know?
