The launch into orbit of the Telstar 1 satellite in July 1962 heralded a new age in communication technology, tantamount to the introduction of the telegraph, or even the printing press. The product of a trilateral agreement between the United States, United Kingdom and France, Telstar 'allowed broadcasting stations in both the U.S. and Europe to send signals up into space, bounce them off the satellite, and have them received across the Atlantic nearly instantaneously, revolutionizing mass communications between the continents. The device could also be used for phone calls and even faxes.'
