The 1990s saw the end of the Internet's founding network, ARPANET
dwarfed by Internet 300,000 host computers in use.
The usefulness of computer networking - especially email - demonstrated by DARPA and Department of Defense contractors on the ARPANET was not lost on other communities and disciplines, so that by the mid-1970s computer networks began springing up wherever funding was found for the purpose, including the Department of Energy's MFENET and HEPNET, NASA's SPAN, the computer science community's CSNET, the academic community's BITNET, and USENET based on Unix UUCP protocols.
Such was the weight of the NSFNET program's ecumenism and funding ($200 million, 1986-1995) and the quality of the protocols themselves that by 1990 when the ARPANET itself was finally decommissioned, TCP/IP had supplanted or marginalized most other wide-area computer network protocols worldwide, and IP was on its way to becoming the bearer service for the Global Information Infrastructure.
When the ARPANET was turned over to the Defense Communication Agency for production work (and cloning) in 1975, there were 57 nodes (see Table 2).
The ARPANET was widely publicized in articles, a short documentary, and a major public demonstration in 1972, and the word got out.
Laboratory, which provided access to ARPANET and a second unclassified military network.
In the 1960s and '70s, ARPANET was "the glue that held the computer science community together," says Kahn.
