Metcalfe’s Law

The law of connections both loved and lost.


Metcalfe’s Law: the value of a telecommunications network is proportional to the square of the number of users of the system (n2). Robert Metcalfe, who coinvented Ethernet along with David Boggs and cofounded 3Com, first formulated his law to explain the network effects of things like joining computers or fax machines together, but it’s just as useful for explaining social networks and the Web.
