FANDOM 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.

The website was popular enough at the time (1999) to get a falloon of their sock puppet dog mascot, Buddy, in the Macy's Parade, as mentioned above. The falloon debuted in the 1999 parade and retired the same year, due to going bankrupt.
