Google is actually the common name for a number with a million zeros.
The Story of Google's Name
Some funny-sounding brand names have made it into history but not many got there because of misspelling. As was Google, which is named after the scientific word that refers to extremely large numbers, googol. The name was suggested by Sean Anderson - as googolplex - to Larry Page - who decided on googol - but looking up on the availability of the domain name Sean misspelled it as google.
