What name is given to the 2000–2002 collapse in internet-company share prices?

The 2000–2002 collapse in internet-company share prices is known as the dot-com crash.

During the late 1990s, investors poured money into internet companies, often valuing firms on expected future growth rather than current profits. The Nasdaq Composite reached a peak of 5,048.62 on March 10, 2000. As expectations changed and many companies failed to produce sustainable revenue, technology shares fell sharply.

The Nasdaq lost about 78 percent of its value from its March 2000 peak to its October 2002 low. Numerous startups failed, while some survivors eventually developed durable business models. The crash also reduced venture funding and corporate investment across the technology sector.

The phrase dot-com bubble describes the speculative boom, while dot-com crash describes the subsequent collapse. The episode was not simply a fall in all technology: several large companies survived and later became dominant businesses.
