Older, but still good documentary about the dot-com bubble from early 2000-s. Would recommend watching to crypto investors now.
The dot-com bubble (also known as the dot-com boom, the tech bubble, and the Internet bubble) was a historic economic bubble and period of excessive speculation mainly in the United States that occurred roughly from 1995 to 2000, a period of extreme growth in the usage and adoption of the Internet.
The Nasdaq Composite stock market index, which included many Internet-based companies, peaked in value on March 10, 2000, before crashing. The burst of the bubble, known as the dot-com crash, lasted from March 11, 2000, to October 9, 2002. During the crash, many online shopping companies, such as Pets.com, Webvan, and Boo.com, as well as communication companies, such as Worldcom, NorthPoint Communications and Global Crossing failed and shut down. Others, such as Cisco, whose stock declined by 86%, and Qualcomm, lost a large portion of their market capitalization but survived, and some companies, such as eBay and Amazon.com, declined in value but recovered quickly.
