By 1984, the US military became concerned about the expansion of the ARPANET and
|
|
|
|
|
its growing non-military applications (see the film _War Games_ released in
|
|
|
|
|
1983!). They split the network into the _ARPANET_ for academic research and the
|
|
|
|
|
_MILNET_ for non-civilian users where transmission was encrypted and protected.
|
|
|
|
|
|
|
|
|
|
Throughout the 1980s, the US National Science Foundation began promoting private
|
|
|
|
|
networks that used the ARPANET as their _backbone_. (Private in the sense of not
|
|
|
|
|
publicly-funded.)

Later, these became commercial and [subscription-based](/zk/Web_precursors.md).
|
|
|
|
|
A plethora of ..._NETS_ grew up (NSFNET, USENET, CSNET, TELENET etc.), all based
|
|
|
|
|
on #packet-switching, the ARPANET nodes as the backbone and
|
|
|
|
|
[TCP/IP](Link_Layer_of_Internet_Protocol.md) host communication.

These networks, although accessible to the public through subscriptions,
|
|
|
|
|
remained unwieldy and inconsistent to access until the Web.
