Root Causes
Pets.com launched in 1998 selling pet supplies online with the iconic 'sock puppet' mascot voiced by Michael Ian Black. It IPO'd in February 2000 at $11/share raising $82.5M with an $82M ad budget featuring a Super Bowl commercial. The problem: pet food is heavy, low-margin, and expensive to ship. Pets.com sold items for roughly a third of what it paid for them, losing an average of $57 on every sale. Nine months after the IPO, on November 7, 2000, the company announced it was going out of business, becoming one of the most-cited symbols of the dot-com collapse alongside Webvan.

1. Physics matters in e-commerce
Shipping heavy, low-margin goods requires either premium pricing or logistics scale — Pets.com had neither.
2. Brand awareness isn't demand validation
Sock-puppet fame didn't translate into repeat orders at prices that could sustain the business.
