Which investment theme dominated the technology-stock bubble that burst in the 2000 dot-com crash?

Internet companies dominated the technology-stock bubble that burst in the 2000 dot-com crash.

During the late 1990s, investors poured money into businesses associated with the rapidly expanding World Wide Web. Many firms received very high valuations despite having limited revenue, persistent losses, or business plans that depended mainly on attracting future users. The enthusiasm helped drive the Nasdaq Composite to a peak in March 2000.

The bubble began to deflate as investors reassessed those valuations and interest rates rose. Numerous dot-com companies failed, while established technology businesses also suffered steep losses. The crash did not mean that the internet itself was a failed idea; companies such as Amazon and eBay ultimately became major businesses. The key distinction is between the technology's long-term importance and the unsustainable prices paid for many related stocks.
