==The Invention of the First Network E-mail==
In 1971, BBN's principal scientist [[Ray Tomlinson]] experimented and hacked the File Transfer Protocol ([[FTP]]) called CPYNET with two other SNDMSG/READMAIL programs that were developed for time sharing systems but they do not have the capability to transmit message from one computer to another. Tomlinson experiment was successful and he was able to transfer messages from his Cambridge lab computer to another. He emailed his group announcing the development and instructions on how to use the first network e-mail.<ref>[http://www.bbn.com/about/timeline/email The First E-mail, A Neat Idea]</ref> Other significant developments during the 1970's include:<ref>[http://www.bbn.com/about/timeline/ BBN Timeline 1970s]</ref>
