A large gateway to the Internet—the NSFNET—was developed in the mid 80s by the National Science Foundation (NSF) with an estimated $121 million in federal funds from the United States government.

In Latin America, Mexico became the first country to get connected to the NSFNET in 1989 whereas Chile, Brazil, and Argentina got their initial connections in 1990. The countries of Venezuela and Ecuador were connected to the NSFNET in 1992 followed by Costa Rica and Peru in 1993. Nicaragua, Colombia, Uruguay, Jamaica and Panama got connected in 1994.

As a step to privatize the global computer network, Sprint Corp., Pacific Bell, Ameritech, and Metropolitan Fiber Systems took over the management of the NSFNET in late 1994.

After nine years in operation, the NSFNET was decommissioned in late April 1995.
