A Two-Minute History of the Internet

The Internet began as the ARPANet, a computer networking project funded by the U.S. government’s Advanced Research Projects Agency in the late 1960s to create a computer network that could enable continued communications during war or natural disasters. What was most original about the ARPANet was the approach it took—the network was decentralized, enabling packets of data to find their way from node to node to reach a destination. This meant that data could take more than one path to its final destination, making the network more resistant to problems.

In the early 1980s, TCP/IP (Transmission Control Protocol/Internet Protocol) was created and became the dominant system for swapping packets on the ARPANet. At about this same time, it became clear that TCP/IP would be used to interconnect various other smaller networks of computers, making it possible to share data on a national or even global scale. The term “Internet” was first used to suggest this larger sort of network.
