History: Anglo-American Tradition With the introduction of the printing press into England in 1476 printing was made easier and faster and made copies less expensive. By the early 16th century two trades dominated the industry: independent printers and booksellers or stationers many of whom were vertically integrated as printers. At the time, the Crown was concerned about sedition and the Church about heresy. In 1557 by royal charter the Stationers' Company of London was created and exclusive rights granted. Approved printers were given the right to copy approved works. Accordingly the roots of copyright were censorship. The Statute of Queen Ann, the first formal copyright law, was passed in 1710. Copyright was then conferred on the author of a work, but still the owner of copyright was nearly always the bookseller. Only in 1775 the House of Lords replaced the common law of printing rights in favor of the author. In this tradition the underlying concept of copyright is monopoly, first granted to printers, then to booksellers and later to individual creators. Copyright is treated as a commodity to be bought and sold and inspired by a need to protect the public from the power of the artist. |

Optical communication system by Aeneas Tacitus, 4th century B.C. Aeneas Tacitus, a Greek military scientist and cryptographer, invented an optical communication system that combines water and beacon telegraphy. Torches indicated the beginnings and the ends of message transmissions while water jars were used to transmit the messages. These jars had a plugged standard-size hole drilled on the bottom side and were filled with water. As those who sent and those who received the message unplugged the jars simultaneously, the water drained out. Because the transmitted messages corresponded to water levels, the sender indicated by torch signal that the appropriate water level has been reached. It is a disadvantage that the possible messages are restricted to a given code, but as this system was mainly used for military purposes, this was offset by the advantage that it was almost impossible for outsiders to understand these messages unless they possessed the codebook. With communication separated from transportation, the distant became near. Tacitus' telegraph system was very fast and not excelled until For further information see Joanne Chang & Anna Soellner, Decoding Device, |
