What was the technology-stock collapse beginning in 2000 commonly called?

The technology-stock collapse beginning in 2000 was commonly called the dot-com crash.

During the late 1990s, investors poured money into internet companies, many of which had little revenue or no established path to profitability. The Nasdaq Composite rose from 751.49 at the start of 1995 to 5,048.62 on 10 March 2000, reflecting extraordinary enthusiasm for technology and online business models.

After the peak, investors became less willing to pay extreme prices for companies with uncertain finances. The Nasdaq fell steeply, and many internet firms closed or were acquired. The index eventually reached a bear-market low of 1,114.11 in October 2002, a decline of roughly 78% from its peak.

The crash did not mean that the internet lacked economic value. Companies such as Amazon and eBay survived and later grew substantially, while many speculative ventures disappeared. The dot-com crash is therefore a useful example of a valuable technology trend being separated from unsustainable stock valuations.
