Google talks about its history in a hilarious way: "In September 1998, Google Inc. opened its door in Menlo Park, California. The door came with a remote control, as it was attached to the garage of a friend who sublet space to the new corporation's staff of three. The office offered several big advantages, including a washer and dryer and a hot tub. It also provided a parking space for the first employee hired by the new company: Craig Silverstein, now Google's director of technology."
The house is barely visible in Google Maps and it's already a touristic attraction. "We plan to preserve the property as a part of our living legacy," said Google spokesman Jon Murchinson.
