What name is given to the 2000–2002 collapse of internet and technology shares?

The 2000–2002 collapse of internet and technology shares is called the dot-com bust.

During the late 1990s, investors poured money into companies associated with the commercial internet. Many firms had little revenue, no profits, and business plans built around rapid user growth. The Nasdaq Composite reached 5,048.62 on 10 March 2000, a peak driven by speculative technology valuations.

As earnings disappointed and interest rates rose, confidence reversed. The Nasdaq fell about 78% from its peak to its October 2002 low. Numerous internet companies failed, while even profitable technology businesses suffered major share-price losses. The recession that followed was comparatively mild in output terms but severe for technology investors and workers.

The dot-com bust is often confused with the 2008 financial crisis. The earlier episode centered on equity overvaluation and corporate failures in technology, media, and telecommunications; the later crisis centered on housing credit, banks, and complex securities.
