Dotcom Bubble
The dot.com bubble refers to the period of unbridled speculation in the 1990s that saw rampant increases in the market value of Internet companies. These companies, across a wide range of sectors, made the Internet central to their strategy, operations, and business model. At the very end of the 1990s and into the early 2000s, many of these companies, with market caps measured in billions but no profits, crashed. Many went bust; the share prices of others plunged.
