Television

No mass-media is more efficient in disinformation and propaganda than TV. And no one seems to be better in influencing that which is considered the truth. e.g. around 67% of the Austrian population in 1999 believe that TV is the most reliable information-media.
Opinion polls show that it is said to be the most realistic media, the only one worth trusting. History tells us the contrary. The combination of words and moving pictures, together with the documentary style of the news, looks sincere, while it produces images in our heads which start working on their own. The Vietnam war was only the first war performed on television ...

But: also watching the news is part of the entertainment show of the media. And therefore they are presented in an entertaining form. Manipulation of the contents of the news is part of the show.
One factor is the issue that news must be reported in a very short period. Several seconds for each catastrophe. Scarcity implies disinformation.
Ted Koppel's movie Revolution in a box demonstrates this:
When the TV-news showed pictures of the nuclear plant accident in Chernobyl, they showed pictures of another - still working - plant. The thought behind was to demonstrate that in this world nothing can stay undetected by the media, to show that still everything is observed and under control - at least in the West.

1713
First typewriter patent filed

In 1714 Henry Mill got granted a patent for his idea of an "artificial machine or method" for forgery-proof writing. Still it was not before 1808 that the first typewriter proven to have worked was built by Pellegrino Turri for his visually impaired friend, the Countess Carolina Fantoni da Fivizzono. The commercial production of typewriters began in 1873.

1727
First photocopies

Searching for the Balduinist fluorescenting phosphor (Balduinischer Leuchtphosphor), an artificial fluorescent, Johann Heinrich Schulze realized the first photocopies, but did not put them into practical use.

The first optical photocopier was not patented before 1843, when William Henry Fox Talbot got granted a patent for his magnifying apparatus.

In 1847 Frederick Collier Bakewell developed a procedure for telecopying, a forerunner of the fax machine. Yet it was not before 1902 that images could be transmitted. Almost 200 years after Schulze's discovery, for the first time photo telegraphy was offered as a telecommunication service in Germany in 1922.

1794
Fixed optical network between Paris and Lille

Claude Chappe built a fixed optical network between Paris and Lille. Covering a distance of about 240kms, it consisted of fifteen towers with semaphores.
Because the communication system was designed for practical military use, the transmitted messages were encoded. The messages were kept such a secret that even those who transmit them from tower to tower did not capture their meaning; they transmitted codes they did not understand. Depending on weather conditions, messages could be sent at a speed of 2880 kms/hr at best.

Forerunners of Chappe's optical network are the Roman smoke signals network and Aeneas Tacitus' optical communication system.

For more information on early communication networks see Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks.
