Or maybe someone else on one of these lists? http://en.wikipedia.org/wiki/List_of_the_largest_software_companies http://en.wikipedia.org/wiki/List_of_the_largest_software_co... http://en.wikipedia.org/wiki/List_of_the_largest_information_technology_companies http://en.wikipedia.org/wiki/List_of_the_largest_information... http://en.wikipedia.org/wiki/List_of_largest_Internet_companies http://en.wikipedia.org/wiki/List_of_largest_Internet_compan...
