Short for National
Science Foundation Network, NSFNET is a network that went
online in 1986 and during the
late 1980's and early 1990's was a crucial
backbone to
ARPANET and the Internet as we know
it today. During 1990 and
1991 NSFNET was
restructured and created a not-for-profit entity and a for-profit
subsidiary to help with the commercial development of the network.
