The Complete History of the Internet: An Year-by-Year Evolution

This year-by-year guide will explore its complete evolution, from ideation during wartime to the present day in 2024, giving you a deeper understanding of how it came to be.

1940s: Early Foundations and the World War II Connection

1945

• Vannevar Bush, an American engineer, published an article titled “As We May Think,” envisioning a system called the Memex, a theoretical device that could store all of an individual’s books, records, and communications. This foresight laid the conceptual groundwork for the idea of hypertext and linked data, critical elements of the future Internet.
• Story Connection: Bush’s work emerged from his leadership in the U.S. Office of Scientific Research and Development during World War II. His efforts to coordinate wartime technology inspired ideas about information sharing on a grand scale, ultimately contributing to the Internet’s ideation.

1950s: The Seed of Ideation

1950 - 1958

• Cold War Influence: As tensions mounted between the USA and the Soviet Union, fears of technological inferiority took hold in the United States. This environment catalyzed technological innovation, particularly in defense and communication.
• Story of ARPA Creation: In 1957, the Soviet launch of Sputnik led the U.S. to create the Advanced Research Projects Agency (ARPA), focusing on cutting-edge technology that could ensure American superiority.

1960s: The Birth of Networking Concepts

1962

• J.C.R. Licklider's Vision: Psychologist and computer scientist J.C.R. Licklider wrote about an "Intergalactic Computer Network." His ideas laid the foundation for what would eventually become the Internet, envisioning computers communicating with each other seamlessly.

1965

• First Wide-Area Network (WAN) Experiment: Lawrence Roberts, working at MIT, connected computers over a telephone line, demonstrating the potential for data communication between distant systems. This marked the first step toward large-scale networking.

1969

• Birth of ARPANET: Funded by the U.S. Department of Defense, ARPANET was the world's first packet-switching network. The first message, "LO" (intended to be "LOGIN"), was sent between UCLA and the Stanford Research Institute but crashed mid-transmission—a simple yet monumental moment.

1970s: The Foundation of Modern Networking

1971

• The First Email: Email was invented by Ray Tomlinson, who introduced the “@” symbol to separate user names from computer names. Email rapidly became the ARPANET’s most popular service. Ray Tomlinson sent the first-ever email, choosing the "@" symbol to separate user names from computer names. This innovation became the backbone of digital communication.

1973

• International Expansion: ARPANET went global when a node was added in Norway, marking the first international connection and setting the stage for a global communication network.
• The concept of networking protocols took a leap forward with Robert Kahn and Vinton Cerf designing TCP/IP (Transmission Control Protocol/Internet Protocol). TCP/IP would later become the standard protocol for the Internet.

1974

• The Term 'Internet': Vinton Cerf and Bob Kahn proposed a new protocol called TCP (Transmission Control Protocol). It was during this period that the term "Internet" was used for the first time, referring to their idea of interconnected networks.

1976

• Queen Elizabeth II sent her first email, making her one of the first heads of state to communicate using this emerging technology.

1978

• Birth of TCP/IP Protocol: Cerf and Kahn's development of TCP/IP became the primary protocol suite for the Internet, establishing a standardized method for network communication.
• The first spam email was sent by a marketer named Gary Thuerk to ARPANET users, marking the beginning of digital marketing (though it was highly controversial).

1980s: From Academic Network to Public Service

1983

• Transition to TCP/IP: On January 1, 1983, ARPANET switched entirely to TCP/IP, marking the official birth of the modern Internet as we know it. This event is celebrated as the beginning of all Internet communications.
• The Domain Name System (DNS): Paul Mockapetris invented the DNS, introducing domains like .com, .org, and .edu, making the Internet more user-friendly.

1984

• The Domain Name System (DNS) was introduced, creating recognizable addresses such as “.com,” “.org,” and “.net.” This simplified the way people accessed websites, making it more user-friendly.

1985

• First Registered Domain Name: Symbolics.com became the first domain name to be registered, marking the beginning of domain name usage that would soon become central to Internet navigation.

1989

• The World Wide Web is Conceived: Tim Berners-Lee, a British scientist working at CERN, proposed an idea for a distributed information system that became the World Wide Web. His goal was to create a way to link and access documents over the Internet using hyperlinks.
