Root Causes
London-based Boo.com aimed to be the world's first pan-European luxury sportswear retailer. It raised $135M and spent 18 months building a 3D-heavy Flash website with virtual dressing rooms, launching simultaneously in 18 countries and 7 languages in November 1999. The site was slow on the 56k modems most consumers had. Kernan Corporate management burned $135M in ~18 months on infrastructure, staff and marketing before revenues materialized. Boo.com went into liquidation May 18, 2000 — becoming the definitive European dot-com implosion, immortalized in Ernst Malmsten's book 'Boo Hoo'.
