Complete lack of regulation, and in many cases, even billing. You cannot make a call on the PSTN without someone getting money from someone else and a CDR (<http://en.wikipedia.org/wiki/Call_detail_record>) being created. Television & radio stations are trivially countable and probably literally a a dozen or more orders of magnitude off the number of packets on the Internet. Railroads are similarly tiny in number and bill for freight. Roads are built by taxpayer dollars, so the gov't keeps a good account. Etc., etc. The Internet is the first world-wide "thing" that doesn't bill based on where you send something, what you are doing, why you do it, and in many cases, even how much you do. Moreover, anyone can set up anything on it without asking the gov't for permission. This has enabled the impossible growth curve seen the last 20 years, but also made it impossible to count, categorize, or control. Which pisses off some people (usually governments), but makes others (e.g. me!) all warm & fuzzy inside. -- TTFN, patrick P.S. I know you already knew the answer to the question, but I figured you wanted it answered when you asked, so I did.
