A 9-year-old Milton Sirotta, nephew of U.S. mathematician Edward Kasner, first used the word googol. Sirotta made this word in 1937, for the number represented by the numeral 1 followed by 100 zeros.

Although names are generally used for ten to a power that is evenly divisible by three, such as 10 to the third, sixth, ninth, twelfth, etc, {thousand, million, billion, trillion, etc} 10 to the 100th would not normally have a name. Ten to the hundredth power is a large number and certainly googol has a fun pronunciation.

The company Google® was named after the number "googol." Someone suggested "googolplex", which is ten to the power of a googol. They shortened it to "googol" and then spelled the word wrong when looking for a domain name that was not yet registered.
