What name is commonly given to the U.S. technology-stock bubble that burst in 2000?

The U.S. technology-stock bubble that burst in 2000 is commonly called the dot-com bubble.

The dot-com bubble developed during the late 1990s as investors poured money into internet companies. Many businesses received very high valuations despite limited revenue, continuing losses, or untested business models. The spread of the World Wide Web encouraged expectations that online commerce would rapidly transform the economy.

The Nasdaq Composite reached a peak of 5,048.62 on 10 March 2000. It then fell sharply as investors questioned whether technology companies could justify their prices. The downturn damaged both listed companies and venture-backed startups, and the Nasdaq ultimately lost roughly 78% from its peak to its October 2002 low.

The crash did not mean the internet lacked economic value. Companies with durable products, strong finances, and sustainable revenue eventually grew. The common mistake is treating every technology company as a dot-com casualty; firms such as Amazon survived the collapse and later expanded substantially.
