Thanks in large part to research by Thomas Merrill and Lawrence Roberts, who created the first computer network using telephone lines, Arpanet came online. It delivered its first message from a computer at the University of California, Los Angeles, to another at the Stanford Research Institute. The system crashed after only the first two letters of the message, “login,” had been transmitted. By the end of the year, four computers were connected to Arpanet.
