In 1973, the U.S. Defense Advanced Research Projects Agency (DARPA) initiated a research program to investigate ways to link networks. This was called the Internetting project and the system of networks which emerged from the research was known as the "Internet."
1986 - U.S. National
Science Foundation (NSF) took over ARPAnet and established NSFnet by connecting
5 universities. Used primarily by scientist and researchers. This provides
the major backbone of communication services for the Internet today.
1990’s - commercial community joined in on the Internet and it became
a public entity.
