The document discusses the dot-com bubble that occurred from 1995-2000. During this period, stock markets saw rapid growth in equity value from the commercial growth of the internet and internet-based companies. Companies were seeing their stock prices increase dramatically if they added "e-" or ".com" to their names. This environment of rapidly increasing stock prices and confidence in future profits led many investors to overlook traditional valuation metrics. The dot-com bubble started before widespread internet usage and did not initially recognize the internet as important, but media coverage of the "information superhighway" in the early 1990s led major companies and investors to put money into internet-focused businesses.
