The Advanced Research Projects Agency (ARPA) was created in 1957 and later headed by Joseph Licklider, who proposed the idea of a global computer network. With funding from the US Department of Defense, scientists and engineers within ARPA created the first long-distance data transmission system, called ARPANET, which was tested on October 29, 1969, between computers at the Stanford Research Institute (SRI) and the University of California, Los Angeles (UCLA). Although there were initial technical difficulties, the project evolved over time to become the internet we know today.
