    Before the internet
    Before the creation of the Internet, the only way to communicate digitally was by telegraph The telegraph was invented in 1840, it emitted electrical signals that traveled through wires connected between an origin and a destination. It used Morse code to interpret the information.

    In 1958 the US founded the Advanced Research Projects Agency (ARPA) through the Department of Defense. ARPA consisted of about 200 top scientists and had a large budget. ARPA focused on creating direct communications between computers in order to communicate between different research bases. In 1962, ARPA created a computer research program under the direction of John Licklider, a scientist at MIT (Massachusetts Institute of Technology).

  • ARPANET

    ARPANET
    By 1967, enough work had been done for ARPA to publish a plan to create a computer network called ARPANET. ARPANET brought together the best work of the teams at MIT, the Natinonal Physics Laboratory (UK) and the Rand Corporation. The network was growing and in 1971 ARPANET had 23 connected points.

  • Tim Berners-Lee

    The WWW concept was designed by Tim Berners-Lee and some scientists at CERN (Conseil Européen pour la Recherche Nucléaire) in Geneva. These scientists were very interested in being able to easily search and display documentation over the Internet. The CERN scientists designed a browser/editor and named it the World Wide Web. This program was free of charge. It is not well known today but many scientific communities started using it at the time.

  • World Wide Web

    World Wide Web
    The system became so popular at CERN that it was opened to the external public in 1991. In fact, its reception was so rapid that by 1997 there were more than 200,000 websites. With the release of WWW technology and browsers, the Internet began to open up to a wider audience: commercial activities, personal pages, etc. This growth accelerated with the emergence of new, cheaper and more powerful computers.

    In 1993 Mark Andreesen of the National Center for SuperComputing Applications (NCSA) in Illinois released Mosaic X, an easy-to-install and easy-to-use browser. It was a marked improvement in the way graphics were displayed. It was very similar to a modern-day browser.

  • Commercialization of the Internet

    Commercialization of the Internet
    With the advent of TCP/IP, individual, educational and commercial networks began to have access to the almost immediate communication and information available on the Internet. Connectivity ceased to be exclusive and became everyone's thanks to the WWW. The commercialization of the Internet led to the development of private network services with TCP/IP that caused, the emergence of virtual education, the transition to digital marketing, the arrival of digital transformation, etc.

  • Google

    After the creation of the WWW, the launch of Google in 1997 marked a new turning point in the history of the Internet. Google brought this network to a wide audience by offering an easy-to-use browser. Today, Google functions as a browser and search engine, has nearly one billion indexed pages and offers easy access to information thanks to its algorithms.

  • Current Internet Scenario

    Current Internet Scenario
    The Internet has changed radically since its origin, as it is no longer just a space where emails are exchanged and information is stored. It is now in all objects and places where it offers value, as the emergence of the Internet of Things makes clear.
