 In 1986, the NSF created NSFNET, a 56 kbit/s backbone to support the NSF-sponsored supercomputing centers.The NSFNET also provided support for the creation of regional research and education networks in the United States, and for the connection of university and college campus networks to the regional networks.The use of NSFNET and the regional networks was not limited to supercomputer users and the 56 kbit/s network quickly became overloaded.
