What happened when the dot com bubble burst?
What happened was that people would start an "Internet" company without any viable business plan, and investors would pour money. Any company with ".COM" or "eSomething" or "netXXX" or whatever would get tons of money from investors, basically selling dreams of getting rich fast. The companies that flourished back than had often no sales and no income, yet they paid high salaries and provided very lucrative benefits to the employees. One of the examples is Mirabilis - company that invented the on-line messenger (ICQ), but provided free service and free products (there were no fees associated with using the ICQ messenger). They got bought for almost half a billion dollars when they had ZERO revenues, by AOL. AOL sold the company, ten years later, for less than 200 million dollars when at that time ICQ (or, as re-branded, AIM) was already providing revenue (from advertisements). Eventually, investors stopped pouring the money in (for various reasons, but amongst others the higher rates and the slower overall economy), and almost immediately companies started going out of business, and then it all blew up.
