Where does the name come from?

Google was named after a number. A pretty big number in fact!

A googol (which is an homonym for the website's name) looks like this :
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
