Slowly but steadily, the network grew and improvements were made.
Branching out from the Arpanet were other networks including academic networks used by universities and also military networks used by the American government. The NSFNET (National Science Foundation Network) was one of the more popular networks, especially among academic users. The rapid growth and evolution of networks was increased dramatically, exceeding expectations, and not long after that, modeled closely after the Arpanet, the Internet we know and love was created.
