The Internet was developed during a period of time, but its beginning was in the 1960s. It began with the development of the so-called ARPAnet in the 1960s.

The ARPAnet was developed by scientists at M.I.T. and ARPA, a U.S. government agency, as a response to the Cold War with Soviet Russia to ensure communications between computers in the event that the Soviets knocked out the telephone system. ARPAnet, connecting four computers, delivered its first message in 1969.

In the early 1970s, other computer networks were added and TCP, or transmission control protocol, on which the modern Internet is based was developed by scientist Vinton Cerf. In 1989, a Swiss programmer named Tim Berners-Lee created the World Wide Web as a place to store information as well as communicate. In 1992, students at the University of Illinois developed the first browser, called Mosaic, and later that year Congress allowed the Web to be used for commercial purposes.
