What was the U.S. stock-market crash called the Dot-com crash centered on?

The Dot-com crash centered on Internet companies, especially newly listed technology businesses whose valuations had risen during the late-1990s boom. Many firms had limited revenue, continuing losses, or business models that investors had not tested through a full economic cycle.

The Nasdaq Composite reached a closing peak of 5,048.62 on March 10, 2000. It then fell sharply as investors reassessed technology valuations, interest rates rose, and confidence in speculative companies weakened. The downturn spread through venture capital, online advertising, telecommunications, and technology employment.

The crash did not mean that every Internet company failed. Amazon and eBay survived and later became major businesses, while many companies disappeared or were acquired. The term “dot-com” refers to the .com domain used by many commercial Internet firms, not to every technology company. The Nasdaq’s peak and subsequent decline are commonly used to mark the bubble’s burst.
