Determinism of media Determination in media

Transforming technologies • media revolutions? • how fast do they occur? • what kinds of changes do they bring? • do they satisfy the existing needs? • do they trigger new desires and new undesired, unplanned uses?

Semaphor Telegraphs / Optical Telegraphs

Transatlantic Telegraph Cable • Cyrus West Field

Project • 1855 – St. John's to Nova Scotia – connecting the American telegraph grid to Newfoundland • Atlantic Telegraph Company founded to attract financing • intensive marketing efforts in American and Great Britain, governmental support earned

Operation • HMS Agamemnon and USS Niagara meet at a rendez – vous point mid Atlantic • cable spliced, then ships sail towards their continents • 1857 - first attempt – failed, cable broke, mission aborted • 1858 – second attempt

Laying of the cable completed – Aug. 1858 • "Glory to God in the highest; on earth, peace and good will toward men.

" • "it is a triumph more glorious, because far more useful to mankind, than was ever won by conqueror on the field of battle. May the Atlantic telegraph, under the blessing of heaven, prove to be a bond of perpetual peace and friendship between the kindred nations, and an instrument destined by Divine Providence to diffuse religion, civilization, liberty, and law throughout the world. " • Field a hero, New York celebrating

Failure • three weeks after completion cable fails – most probably due to construction shortcomings and technical errors (splicing of the cable, insufficient insulation – too large currencies sent through the cable due to chief engeneer's inexperience • Field riduculed, accused of a hoax, of speculation scam, and of treason by American media

SS Great Eastern • Isambard Kingdom Brunel • by far the largest ship of her era • built to travel around the globe without refueling

SS Great Eastern • • • idea in 1851 commissioned in 1852 laid down in 1854 launched in 1858 maiden voyage in 1859 first voyage to America in 1860 bellied up (economically) in 1863 sold for £ 25. 000 in 1863 built for approx. £ 510. 000

Laying of the cable – re-embarked • The Great Eastern chartered to the Telegraph Construction and Maintenance Company • The Great Eastern – the only existing ship to carry the cable in 'one spool' (4260 km) – no splicing necessary • 1865 – operation begins • 1865 – cable breaks – nearly 2. 000 km of the cable lost • Field finds still a new investor and forms the Anglo. American Telegraph Company • 1866 – cable sucessfully laid. Message from Queen Victoria… • The 1865 cable recovered, spliced and reconnected – two cables operational • 1866 cable could transmit eight words a minute
