How Much Information Is Shared on the Internet?

If the global sharing is sort of zero one or phenomena, like one phenomena, it would be exactly like how we understand the internet. I think that to put in another way, how much information is shared should be quantified. It's quantified by some very crude measures of bandwidth, but not by first principle of mathematics. Everyone you pick on the street, all of your friends who grew up with, everybody has no serious mathematical formulation of how information is.
