Google – accidental misspelling of googol.[11] According to Google's vice president, as quoted on a BBC The Money Programme documentary, January 2006, the founders – noted for their poor spelling – registered Google as a trademark and web address before someone pointed out that it was not correct.

Not to be confused with Google.
A googol is the large number 10100; that is, the digit 1 followed by 100 zeroes:
10,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000.
