    ARPANET establishes a satellite link connected the Norwegian Seismic Array (NORSAR.
    In 1973 the network expands to Hawaii and London as well as increasing its presence in the 48 contiguous states. Also, a transatlantic satellite link connected the Norwegian Seismic Array (NORSAR) to the ARPANET, making Norway the first country outside the US to be connected to the network.

    ARPANET declared "operational" and The Defense Communications Agency took control .
    In 1975, the ARPANET was declared "operational". The Defense Communications Agency took control since ARPA was intended to fund advanced research.[45] At about this time, the first ARPANET encryption devices were deployed to support classified traffic.

  • First Email Sent

  • The Domain Name System (DNS) is established

    The Domain Name System (DNS) establishes the familiar .edu, .gov, .com, .mil, .org, .net, and .int system for naming websites. This is easier to remember than the previous designation for websites, such as 123.456.789.10.
  • First Web Browser, Mosaic Released

  • NetScape Navigator Began Based on Mosaic

  • Internet Service Providers (ISPs) offer Internet access to all. America Online (AOL) and CompuServe were two of those providers.

  • Internet Explorer 1 (Microsoft Internet Explorer) Released

  • ICANN (Internet Corporation for Assigned Names and Numbers) Developed

    ICANN is a not-for-profit public-benefit corporation with participants from all over the world dedicated to keeping the Internet secure, stable and interoperable.
