Boo.com was a British Internet company founded by Swedes Ernst Malmsten, Kajsa Leander and Patrik Hedelin that famously went bust following the dot-com boom of the late 1990s.
After several highly publicised delays, Boo.com launched in the Autumn of 1999 selling branded fashion apparel over the Internet. The company spent $135 million of venture capital in just 18 months, and it was placed into receivership on 18 May 2000 and liquidated. In June 2008, CNET hailed Boo.com as one of the greatest defunct websites in history. Ernst Malmsten wrote about the experience in a book called "boo hoo" published in 2001.
