Did US government invent the Internet?

Everyone knows the government in the body of Albert Gore, Jr., invented the internet. Listen to President Obama. Wrong!; the government's role was small. The US government let a key technology languish for 30 years before private industry made use of it in 1995! And the internet took off only then.

… It's an urban legend that the government launched the Internet. The myth is that the Pentagon created the Internet to keep its communications lines up even in a nuclear strike. The truth is a more interesting story about how innovation happens—and about how hard it is to build successful technology companies even once the government gets out of the way.

For many technologists, the idea of the Internet traces to Vannevar Bush, the presidential science adviser during World War II who oversaw the development of radar and the Manhattan Project. In a 1946 article in The Atlantic titled "As We May Think," Bush defined an ambitious peacetime goal for technologists: Build what he called a "memex" through which "wholly new forms of encyclopedias will appear, ready made with a mesh of associative trails running through them, ready to be dropped into the memex and there amplified."

That fired imaginations, and by the 1960s technologists were trying to connect separate physical communications networks into one global network—a "world-wide web." The federal government was involved, modestly, via the Pentagon's Advanced Research Projects Agency Network. Its goal was not maintaining communications during a nuclear attack, and it didn't build the Internet. Robert Taylor, who ran the ARPA program in the 1960s, sent an email to fellow technologists in 2004 setting the record straight: "The creation of the Arpanet was not motivated by considerations of war. The Arpanet was not an Internet. An Internet is a connection between two or more computer networks."

Note the distinction between a computer network (one owner) versus a connection between networks; the latter is the key. Meanwhile at Xerox Corporation...

… Xerox's copier business was lucrative for decades, but the company eventually had years of losses during the digital revolution. Xerox managers can console themselves that it's rare for a company to make the transition from one technology era to another.

As for the government's role, the Internet was fully privatized in 1995, when a remaining piece of the network run by the National Science Foundation was closed—just as the commercial Web began to boom. Economist Tyler Cowen wrote in 2005: "The Internet, in fact, reaffirms the basic free market critique of large government. Here for 30 years the government had an immensely useful protocol for transferring information, TCP/IP, but it languished. . . . In less than a decade, private concerns have taken that protocol and created one of the most important technological revolutions of the millennia."
