1713
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
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
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

Ciphers as well as codes are transmitted openly. Everyone can see that they exist. Not so with steganograms.
Steganography is the art and science of communicating in a way which hides the existence of the secret part in that communication. During the Italian Renaissance and the time of the Elizabethan Age in England cryptography was very popular, for political reasons as well as for amusements (see John Dee).
In literature steganography played an important role. Many steganographs of that period have only been deciphered recently like some of the Shakespearean sonnets, which now seem to proof that the actor William Shakespeare was not the author of the famous poems and dramas, but that the latter' name was, and Francis Bacon, or even Francis Tudor, as some ciphers and other sources talk of him as Queen Elisabeth I.'s secret son.
for further details see:
One kind of steganogram is digital watermarking:
Watermarks protect digital images, videos, but also audio and multimedia products. They are made out of digital signals, put into other digital signals. They try to be invisible on first sight and should be nearly impossible to remove. The process of producing watermarks is to overlay some sort of identifying image over the original image (non-digital watermarks, like on money can be seen by holding the paper against light). Copying the image destroys the watermark, which cannot be copied. Any alteration of the original destroys the watermark, too.
Watermarking is one of the typical inventions of cryptography to assist the biggest content owners, but advertised as something necessary and helpful for everybody. Who in fact gets any advantage out of watermarking? The private user most of the time will not really need it except for small entities of pictures maybe.
But the big enterprises do. There is a tendency to watermark more and more information in the Internet, which until now was considered as free and as a cheap method to receive information. Watermarking could stop this democratic development.

American audiologist and inventor wrongly remembered for having invented the telephone in 1876. Although Bell introduced the first commercial application of the telephone, in fact a German teacher called Reiss invented it.

This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network.

According to Barbrook and Cameron there is an emerging global orthodoxy concerning the relation between society, technology and politics. In this paper they are calling this orthodoxy the Californian Ideology in honor of the state where it originated. By naturalizing and giving a technological proof to a political philosophy, and therefore foreclosing on alternative futures, the Californian ideologues are able to assert that social and political debates about the future have now become meaningless and - horror of horrors - unfashionable. - This paper argues for an interactive future.
