millions of people own computers but there is no set number since people are always buying more. Whoever wrote this above me is a idiot there is "billions" of people who own computers to find a rough estimate you find out how many people use the internet which is easier. About seven billion people worldwide use the internet and then you still have the small amount of people who don't use the internet. Just make estimates off that. Whoever wrote that "seven billion people" worldwide use the internet is legally retarded.
