> The book takes us through a series of key moments in the development of the internet: 1969, when the publicly owned Advanced Research Projects Agency Network (ARPANET), the first public computer network that became a forerunner to the internet, went live for the first time; 1976, when the Defense Advanced Research Projects Agency (DARPA) linked two networks for the first time in pursuit of its goal to “bring the mainframe to the battlefield”;
The only mention of a military application is related to the event of DARPA linking two networks for the first time. This is in fact what happened. That event has nothing to do with the creation of ARPANET, which is clearly mentioned here as a distinct, earlier event. There's no other mention in the article of a military motivation for the creation of the Internet, or other computer technology.
