The first impetus for the emergence of the Internet was the Cold War between the Soviet Union and the United States. Specifically the successful launch of the Soviet Sputnik 1 spacecraft in 1957. The Soviets had a certain lead in the field of technological struggle and the Americans did not want to lag behind. Therefore, in February 1958, the research agency ARPA (Advanced Research Projects Agency) was established, focusing on research and development of cutting-edge military technologies.
The first forerunner of the Internet was the ARPANET, whose idea came from researcher Bob Taylor, who had three computer terminals connected to communicate with three different locations. He wondered why he didn't use a single terminal to communicate. In February 1966, he received funding for the project.
The aim of the project was to create a computer network that would improve the management of the armed forces and at the same time, thanks to its decentralization, was functional even in the event of significant damage. Another more practical goal was to solve the problem of researchers' access to powerful computers, which were not easy to access. Especially if the research institution was far from such a machine.
Over time, other networks based on the TCP/IP protocols emerged, the main purpose of which was to interconnect the computer infrastructure to facilitate access.
Since the 1980s, there has been pressure from the commercial sector to use the infrastructure, which has led to the establishment of the first Internet service provider (ISP) companies. The last step in the creation of the Internet as we know it today was the release of the last restriction for the commercial use of the Internet in April 1995.
