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

-1994
Viacom multimedia and industrial corporation takes control of Paramount Communications for US$ 9.6 billion, as well as Blockbuster Entertainment, a huge video store chain, for US$ 8.4. billion.
1995
Entertainment giant Disney buys Capital Cities-ABC for US$ 19 billion.
The industrial and broadcasting company Westinghouse Corp. buys out CBS for US$ 5.4 billion.
In a US$ 7.2 billion deal, Time Warner acquires Turner Communications, owner of prime cable TV channels CNN, TBS and TNT and a major classic American film library.
1996
Westinghouse/CBS buys Infinity Broadcasting's large group of radio stations.
Murdoch and News Corp. acquire ten more TV stations and TV production studios with the US$ 2.5 billion purchase of New World Communications Group.
Viacom buys half of UPN-TV network, adding that to its other holdings, which include eleven TV stations, along with MTV, VH-1, and other cable TV channels and Paramount movie studios.
1997
Radio Groups Chancellor Media and Evergreen merge and are linked by ownership with Capstar Broadcasting; they also buy ten radio stations from Viacom. By mid-1997 Chancellor/Capstar controls no fewer than 325 radio stations around the United States.
Chancellor/Capstar's controlling ownership group, Hicks Muse Tate & Furst, buys the seventh largest radio group, SFX, adding another seventy-two radio stations, making a total of nearly four hundred stations controlled by this one source.
Westinghouse-CBS buys out American Radio Systems, the fourth largest radio chain in total audience, which gives Westinghouse-CBS over 170 radio stations with a total audience nearly equal to that of the Chancellor/Capstar group.
Giant European-based print and electronic publishing and data base corporations Reed Elsevier and Wolters Kluwer merge.
1998
Bertelsmann buys the Random House-Alfred A. Knopf-Crown Publishing group of book publishers from Newhouse/Advance Publications, adding to its Bantam-Doubleday-Dell publishing group and giving Bertelsmann by far the largest English-language publishing operations.

Communications satellites are relay stations for radio signals and provide reliable and distance-independent high-speed connections even at remote locations without high-bandwidth infrastructure.
On point-to-point transmission, the transmission method originally employed on, satellites face increasing competition from
In the future, satellites will become stronger, cheaper and their orbits will be lower; their services might become as common as satellite TV is today.

Automation is concerned with the application of machines to tasks once performed by humans or, increasingly, to tasks that would otherwise be impossible. Although the term mechanization is often used to refer to the simple replacement of human labor by machines,
This document, intended as a reliable electronic reference tool, provides a timeline for three types of developments and milestones: (1) advances in long distance person-to-person communication; (2) advances in storage, replication, cataloguing, finding, and retrieval of data; and (3) standardization of concepts and tools for long distance interaction.
The advancements may have a technical (hardware), conceptual (software), or an organizational aspect, or represent an important milestone in the history of a given invention, and are annotated as such in the timeline.
The period covered ranges from 30000 BC up to now.
