Internet History Timeline: ARPANET to the World Wide Web

Credit for the initial concept that developed into the World Wide Web is typically given to Leonard Kleinrock. In 1961, he wrote about ARPANET, the predecessor of the Internet, in a paper entitled “Information Flow in Large Communication Nets.” Kleinrock, along with other innnovators such as J.C.R. Licklider, the first director of the Information Processing Technology Office (IPTO), provided the backbone for the ubiquitous stream of emails, media, Facebook postings and tweets that are now shared online every day. Here, then, is a brief history of the Internet:

The precursor to the Internet was jumpstarted in the early days of computing history, in 1969 with the U.S. Defense Department’s Advanced Research Projects Agency Network (ARPANET). ARPA-funded researchers developed many of the protocols used for Internet communication today. This timeline offers a brief history of the Internet’s evolution:

History of Computers – A Brief Timeline of Their Evolution

The computer was born not for entertainment or email but out of a need to solve a serious number-crunching crisis. By 1880, the U.S. population had grown so large that it took more than seven years to tabulate the U.S. Census results. The government sought a faster way to get the job done, giving rise to punch-card based computers that took up entire rooms.

Today, we carry more computing power on our smartphones than was available in these early models. The following brief history of computing is a timeline of how computers evolved from their humble beginnings to the machines of today that surf the Internet, play games and stream multimedia in addition to crunching numbers.

1801: In France, Joseph Marie Jacquard invents a loom that uses punched wooden cards to automatically weave fabric designs. Early computers would use similar punch cards.

1822: English mathematician Charles Babbage conceives

The Invention of the Internet – Inventor, Timeline & Facts

  4. The Network Grows
  5. The World Wide Web

Unlike technologies such as the light bulb or the telephone, the internet has no single “inventor.” Instead, it has evolved over time. The internet got its start in the United States more than 50 years ago as a government weapon in the Cold War. For years, scientists and researchers used it to communicate and share data with one another. Today, we use the internet for almost everything, and for many people it would be impossible to imagine life without it.

The Sputnik Scare

On October 4, 1957, the Soviet Union launched the world’s first manmade satellite into orbit. The satellite, known as Sputnik, did not do much: It relayed blips and bleeps from its radio transmitters as it circled the Earth. Still, to many Americans, the beach-ball-sized Sputnik was proof of something alarming:
