  • Lawrence Roberts & Thomas Marill Create First Wide-area Network

    Lawrence Roberts & Thomas Marill Create First Wide-area Network
    Lawrence Roberts (MIT) and Thomas Marill get an ARPA contract to create the first wide-area network (WAN) connection via long distant dial-up between a TX-2 computer in Massachusetts and a Q-32 computer in California. The system confirms that packet switching offers the most promising model for communication between computers.
  • ARPAnet Project Initiated

    ARPAnet Project Initiated
    Directing ARPA’s computer research program, Robert Taylor initiates the ARPAnet project, the foundation for today’s Internet.
  • ARPAnet Design Begins

    ARPAnet Design Begins
    Lawrence Roberts leads ARPAnet design discussions and publishes first ARPAnet design paper: "Multiple Computer Networks and Intercomputer Communication." Wesley Clark suggests the network is managed by interconnected ‘Interface Message Processors’ in front of the major computers. Called IMPs, they evolve into today’s routers.

    Robert Kahn Demonstrates ARPAnet to Public
    Robert Kahn demonstrates the ARPAnet to the public for the first time by connecting 20 different computers at the International Computer Communication Conference, and in doing so, imparts the importance of packet-switching technology.
  • Danny Cohen Pioneers Network Voice Protocol

    Danny Cohen Pioneers Network Voice Protocol
    Danny Cohen was the first to implement “packet video” and “packet voice” (Network Voice Protocol) when he adapted the visual flight simulator to run over the ARPANET in 1973. It was the first application of packet switching to real-time applications.
