"Important anticipations of hypertext can be found in the computerized communications networks, such as ARPANET or BITNET, put in place in the 1960s and 1970s. Such a network constitutes the physical embodiment of hypertext. Each element or node in the network is a computer installation, while the connections among these elements are cables and microwave and satellite links. Each computer node serves dozens or hundreds of individual subscribers, and these subscribers both produce and read messages created by others within their computing facility, around the nation, or around the world. Some messages travel a single path through the communications links until they reach their marked destination, while general messages spread out to all the elements in the net. At any one moment the network holds a vast text of interrelated writings the intersection of thousands of messages on hundreds of topics. It is a hypertext that no one reader can hope to encompass, one that changes moment by moment as messages are added and deleted."
