Which technology-focused stock-market bubble burst in March 2000?

The technology-focused stock-market bubble that burst in March 2000 was the dot-com bubble.

The bubble centered on internet-related companies, many of which had little revenue or no profits but attracted enormous investment because investors expected rapid online growth. Businesses frequently used “.com” domain names, giving the episode its popular label.

The Nasdaq Composite, heavily weighted toward technology shares, reached a peak on March 10, 2000. It then fell sharply as investors reassessed valuations, business models, and the ability of new companies to earn sustainable profits. The downturn continued for several years, damaging many firms and reducing technology-stock wealth.

The crash did not mean the internet was unimportant. Online commerce and digital services later became major industries, but the bubble showed that a promising technology can coexist with unrealistic share prices and weak company finances.
