The dot-com bubble of the late 1990s saw endless waves of investment in internet companies fueled by excitable media reports, creating a feedback loop where momentum fed itself. Some startups spent money extravagantly, such as a company that flew in a top New York hairdresser to redesign the hair of a digital avatar. More ordinary individuals also got swept up in the frenzy as investment clubs spread. The enthusiasm crossed social boundaries and involved much of the public, who were watching financial news networks closely. Traditional valuation of companies was ignored as momentum and hype took over.
