What was the 2000–2002 collapse in internet-company shares commonly called?

The 2000–2002 collapse in internet-company shares was commonly called the dot-com crash.

During the late 1990s, investors bid up companies associated with the rapidly expanding internet. Many firms had limited revenue, no profits, or business plans based mainly on future growth, yet their share prices rose dramatically.

The Nasdaq Composite reached a peak on 10 March 2000. As expectations changed, technology shares plunged, many internet startups failed, and venture funding became harder to obtain. The Nasdaq eventually fell about 78% from its peak to its October 2002 low.

The crash did not mean the internet lacked commercial value. Companies with stronger finances and sustainable models survived or later prospered, while the episode showed that a promising technology can still be surrounded by unsustainable speculation.
