As much as I would love to agree with Crovitz, his column promises more than it delivers. The essence of his column is that Xerox developed the communications protocol upon which the internet relies. True enough. But which wing is more important to an airplane, the right wing or the left wing. A communications protocol needs a network to run on. ARPANET connected universities engaged in DoD research and was itself funded by ARPA, which was (and DARPA still is) part of DoD. Were there other contributors? To be sure. But we should not dismiss DoD's role so cavalierly.
