Who runs the Internet?

I'm just going through all my data at the moment and attempting to once and for all bring some order to the chaos. Amongst the chaos I found all my old bookmarks.

Still I found one link which was useful and thought I'd throw it up here in case any of you readers were also curious about who and how the Internet actually runs. Who makes the decisions? This article should clear it up for you.
