History of Communication |
|
The oldest known symbols created
with the purpose of communication through time are the cave paintings |
|
A Graphic symbol that represents
an idea or concept is called as Ideograph |
|
The Egyptians had their own set of
symbols to keep track of trade They developed a system of writing known
as hieroglyphics |
|
Hieroglyph script was
developed about four thousand years before Christ and there was also a
decimal system of numeration up to a million. |
|
Egyptian hieroglyphics consisted
of two types of symbols: ideograms and phonograms. Ideograms
evolved from pictographs and were symbols of both objects and ideas |
|
The earliest known journalistic
product was a news sheet circulated in ancient Rome and called the Acta
Diurna |
|
Cuneiform script is one of the earliest known forms of written
expression |
|
The cuneiform writing system was
in use for more than 35 centuries, through several stages of evolution, from
the 34th century BC down to the 1st century AD |
|
In greek 500 BC
developed a system to communicate from one city to another
city that system is called as Visual telegraph |
|
The visual Telegraph was by
building a series of brick walls with indentations at the top.
Each indentation represented a letter of the Greek alphabet. To send a
message, people lit fires at the appropriate spots to send express a message.
A watcher at the next wall would resend the message to wherever it needed to
get to |
|
PAPYRUS: is a tall, aquatic reed plant, Cyperus Papyrus, noted
especially for its use for ancient writing material. The papyrus plant,
so abundant in ancient Lower Egypt |
|
Coranto is a term used to describe early informational
broadsheets precursors to newspaper |
|
In the English-speaking world, the
earliest predecessors of the newspaper were corantos, small news
pamphlets produced only when some event worthy of notice occurred. |
|
By December 1620, Corantos
(single folio sheets) of news about the wars in Europe, printed in
English, were making their way across the English Channel from Holland. |
|
The formal study of language began
in India with Panini the 5th century BC
grammarian who formulated 3,959 rules of Sanskrit morphology. |
|
When writing evolved in the human
world, communications came into existence. Postal services long existed in
China since 4000 BC. Millennium later, Egypt and Assyria had their postal
services. |
|
The Chinese and Egyptian services
were confined to imperial court circles, but in Assyria the service was open
to the mercantile class. |
|
Historical references to postal
systems in Egypt dated from about 2000 BC |
|
The two Greek historians, Herodotus
and Xenophon, wrote the detailed descriptions about the postal
network. |
|
Rowland Hill formulated proposals on reforming the modern postal system
between 1835 and 1837. |
|
A telegraph is
a device for transmitting and receiving messages over long distances, i.e.,
for telegraphy. |
|
Beginning in 1836, the American
artist Samuel F B Morse the American physicist Joseph Henry
and Alfred Vail developed an electrical
telegraph system. |
|
The Morse code was
developed so that operators could translate the indentations marked on the
paper tape into text message |
|
Morse code is a method of
transmitting textual information as a series of on-off tones,
lights, or clicks that can be directly understood by a skilled listener or
observer without special equipment |
|
The first successful
submarine telegraph was laid between Dover and Calais, a distance of
twenty-four miles, in 1850 |
|
The transatlantic
telegraph cable was the first cable used for
telegraph communications laid across the floor of the Atlantic
Ocean in 1866 from Ireland to Canada |
