If you mean the very large number 10^100, as used by mathematicians,
then its name is "googol", not google.

AIUI, the name google was chosen to resonate with googol - or maybe it
was some marketer ignorant of the correct spelling. Good thing too, I
say.

It's a pun - it's "go ogle", as in, "go and look for", but it sounds a bit
like "googol", giving the idea that it returns lots of results.

And given Google's origins, I rather doubt there were any marketers
involved. It was initially a university experiment in inexpensive Linux
clustering.
