Pets.com was a dot-com enterprise that sold pet supplies to retail customers. It began operations in August 1998 and closed in November 2000. A high-profile marketing campaign gave it a widely recognized public presence, including an appearance in the 1999 Macy's Thanksgiving Day Parade and an advertisement in the 2000 Super Bowl. Its popular sock puppet advertising mascot was interviewed by People magazine and appeared on Good Morning America.
Although sales rose dramatically due to the attention, the company was weak on fundamentals and lost money on most of its sales. Its high public profile during its brief existence made it one of the more noteworthy failures of the dot-com bubble of the early 2000s. US$300 million of investment capital vanished with the company's failure. The company was headquartered in San Francisco.
