The Internet was conceived in the 1960s. A report had been written by the Rand Corporation for the United States government in the 1960s. This report outlined a vision of the future information network and described a view of information becoming a material good and the principal commodity of the 21st century. The U.S. government agency called the Defense Advanced Research Project Agency (DARPA) invested several billion dollars in developing packet-switching networks starting in the mid-1960s through the early 1970s. Initially, the customer for these switching networks was the U.S. Department of Defense; however, many of the researchers that had been contracted to carry out the research and development were scholars. These scholars became enamored with the test systems that they had built and realized that their work had applications beyond defense. Initially, the research network was called the Advanced Research Project Agency Network (ARPANET), but later it was called the Internet (which stands for Inter Network). The first e-mail was sent in 1972. Figure 11-1 is a rendering of the Internet.
