ARPANET, the first real prototype of the internet, was launched by ARPA to allow researchers at different universities to share computer resources.

By 1971, Ray Tomlinson sent the first network email and introduced the "@" symbol. By 1973, ARPANET became international, connecting nodes in Norway and the UK. 3. The Invention of TCP/IP (1970s–1983)

As more independent networks emerged, they were often incompatible. and Bob Kahn , often called the "Fathers of the Internet," solved this by designing a universal language.

The journey began in the late 1950s, catalyzed by the Cold War.

They developed TCP/IP (Transmission Control Protocol/Internet Protocol). TCP handles data assembly/disassembly, while IP ensures packets reach the correct address.

On January 1, 1983, ARPANET officially switched to TCP/IP. This "network of networks" approach is what technically defined the birth of the "Internet". The Internet | Johan Norberg's New and Improved

The creation of the internet was not a single "eureka" moment but a decades-long evolution involving government agencies, academic researchers, and visionary computer scientists. It transitioned from a Cold War-era military project into the global, commercial network we use today. 1. The Seeds of Connectivity (1950s–1960s)

In the early 1960s, researchers like Leonard Kleinrock , Paul Baran , and Donald Davies independently developed "packet switching". This method breaks data into small "packets" that can take different routes to a destination and reassemble upon arrival, making networks more resilient than traditional telephone lines. 2.
