Prestel
In 1983, the Prestel messaging service known as “Prestel Mailbox” was launched, initially hosted on the computer known as "Enterprise", and later available from all IRC computers by means of a centralised messaging computer known as "Pandora". This facility extended the original day one concept of “Response Frames” whereby an end user could send a message back to the IP who owned the page via special pages, for example to order goods or services. The user’s name, address, telephone number, and date could be added automatically to the message when the IP set up the response frame by means of codes which triggered extraction of key data from the users account held on the IRC computer. Initially response frames were ingathered by an IP from each IRC individually, but later the facility to collect messages from all IRCs at the UDC from where they could be ingathered centrally was implemented, and with the introduction of Mailbox, they could be retrieved from any IRC.
List of Internet pioneers
Danny Cohen led several projects on real-time interactive applications over the ARPANet and the Internet starting in 1973. After serving on the computer science faculty at Harvard University (1969–1973) and Caltech (1976), he joined the Information Sciences Institute (ISI) at University of Southern California (USC). At ISI (1973–1993) he started many network related projects including, one to allow interactive, real-time speech over the ARPANet, packet-voice, packet-video, and Internet Concepts. In 1981 he adapted his visual flight simulator to run over the ARPANet, the first application of packet switching networks to real-time applications. In 1993, he worked on Distributed Interactive Simulation through several projects funded by United States Department of Defense. He is probably best known for his 1980 paper "On Holy Wars and a Plea for Peace"
which adopted the terminology of endianness for computing.
