TeletypesettingIn 1951, the Associated Press started using their new "teletypesetting" service in Charlotte, NC. The news article information was transmitted using a perforated, paper tape. At the receiving end of the circuit, a punch produced a copy of the perforated tape. This tape could then be used by typesetting machines. The first message sent was "Greetings. This is the opening of the first teletypesetter circuit," for they were the first news agency in the U.S. to begin such operation. |
