As you may expect for a technology so expansive and ever-changing, it is not possible to credit the invention of the Internet to a single person. The Internet was the work of dozens of pioneering scientists, programmers and engineers who each developed new features and technologies that eventually merged to become the “information superhighway” we know today.
Quite a bit before the technology existed to actually build the Internet, many scientists had already anticipated the existence of worldwide networks of information.
Nikola Tesla toyed with the idea of a “world wireless system” in the early 1900s, and visionary thinkers like Paul Otlet and Vannevar Bush conceived of mechanized, searchable storage systems of books and media in the 1930s and 1940s.
Still, the very first practical schematics for the Internet would not arrive until the early 1960s, when MIT’s J.C.R. Licklider popularized the idea of an “Intergalactic Network” of computers. Shortly thereafter, computer scientists developed the concept of “packet switching,” a method for effectively transmitting electronic data that would later become one of the major building blocks of the Internet.
The very first workable prototype of the Internet came in the late 1960s with the creation of ARPANET, or the Advanced Research Projects Agency Network.
Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to interact on a single network. The technology continued to grow in the 1970s after scientists Robert Kahn and Vinton Cerf developed Transmission Control Protocol and Internet Protocol, or TCP/IP, a communications model that set standards for how data could be transmitted between multiple networks.
ARPANET adopted TCP/IP on January 1, 1983, and from there researchers began to assemble the “network of networks” that became the modern Internet.
The internet world then took on a more recognizable form in 1990, when computer scientist Tim Berners-Lee invented the World Wide Web.
While it’s often confused with the Internet itself, the web is basically just the most common means of accessing data online in the form of websites and hyperlinks.
The web helped popularize the Internet among the public, and served as a crucial step in developing the vast trove of information that most of us now access on a daily basis.
