What name describes the collapse of technology-stock valuations beginning in 2000?

The collapse of technology-stock valuations beginning in 2000 was called the dot-com bubble burst.

The bubble formed during the late 1990s as investors poured money into internet-related companies. Many firms attracted high valuations despite limited revenue, continuing losses, or business models that had not yet proved viable. The Nasdaq Composite reached a peak on March 10, 2000, before falling sharply.

The decline wiped out large amounts of market value and caused many internet startups to close or enter bankruptcy. Established technology companies also lost value, although some eventually became highly successful as internet use expanded.

The dot-com bubble burst is distinct from the 2008 crash, which centered on housing finance and the banking system. It is also different from an ordinary technology-sector correction because the earlier episode involved broad speculative enthusiasm across internet stocks.
