NSFNET history

The National Science Foundation Network (NSFNET) was a program of coordinated, evolving projects sponsored by the National Science Foundation (NSF) from 1985 to 1995 to promote advanced research and education networking in the United States.1 The program created several nationwide backbone computer networks in support of these initiatives. It was created to link researchers to the NSF-funded supercomputing centers. Later, with additional public funding and also with private industry partnerships, the network developed into a major part of the Internet backbone.

The National Science Foundation permitted only government agencies and universities to use the network until 1989 when the first commercial Internet service provider emerged. By 1991, the NSF removed access restrictions and the commercial ISP business grew rapidly.2
