What technology-related sector fueled the U.S. stock-market bubble that burst in the 2000 dot-com crash?

Internet companies fueled the U.S. stock-market bubble that burst in the 2000 dot-com crash.

The dot-com bubble centered on businesses associated with the rapidly expanding World Wide Web. Investors poured money into companies with “.com” in their names, often valuing expected future growth far more heavily than current profits or revenue.

The Nasdaq Composite, which contained many technology and internet stocks, reached a peak of 5,048.62 on March 10, 2000. It then declined dramatically as investors reassessed business models, rising interest rates, and the difficulty of turning website traffic into sustainable earnings.

Many internet start-ups failed, while a smaller group of companies survived and later became major businesses. The crash did not show that the internet lacked commercial value; it showed that exciting technology could still be paired with unrealistic prices and weak finances.
