Evolution of Communication

From writing on walls to advanced
fiber optics.

Basic Communications


Communications
-
the process of creating
and exchanging meaning trough symbolic
interaction.


Written communication
-

Any communication
that is written and can be read.


Verbal communications
-

Any communications
that is spoken.


Non verbal communications
-

Communications that is not spoken.

Ancient Communication


Cave drawings on walls depicting nature
and surroundings.


This is the first known exchange of
information from one person to
another.

Thought to be over 35,000 years old

Some theories hold that they may have been a way
of transmitting information, while other theories
ascribe them a religious or ceremonial purpose.


Found
in
Lascaux
,France.

Speaking and Writing


Researches believe that speaking and language
developed next. First starting from grunts and
sounds to complex word structures eventually
evolving into languages.



Since the most ancient languages known in the
worlds were undocumented and eventually were
absorbed into other languages it is not really known
what the absolute oldest languages are.



Speaking and Writing


What we know as some of the oldest languages like
Hebrew and Aramaic are probably byproducts of
several earlier languages that have know historic
record.

Books and literature


After learning to speak and write tribes turned into empires and
began to document their history.


They did this by drawing on walls and tablets, or sculpting
figures that represented their beliefs and religions.


Early Writing


The earliest known writing was etched onto jars before and
after firing. Experts believe they may have indicated the
contents of the jar or be signs associated with a deity.



Tablets


Eventually, as these tribes evolved technology they
began to write on tablets.


Hieroglyphics


The ancient Egyptians were famous for documenting their
history. Their written language called hieroglyphics were very
colorful and used images to represent words and phrases. This
type of language one that uses images is called pictography.
Although the Egyptians were not the first to use pictography
they are more well knows because of the massive scale and
artistry that went into the images.


Books and Literature


Eventually tribes began to develop parchment and paper that
were easier to reproduce and obtain at the common level.
When reading and writing in the ancient world became more
common place stories and literature gave way to some of the
earliest known books.



The earliest books were written on scrolls. From the Second
Century A.D. to the present time.

Scrolls

The
Dead Sea scrolls

consist of roughly 900
documents, including texts
from the
Hebrew Bible
,
discovered between 1947
and 1956 in eleven
caves

in
and around the Wadi
Qumran

near the ruins of the ancient
settlement of
Khirbet
Qumran
, on the northwest
shore of the
Dead Sea
. The
texts are of great religious
and historical significance, as
they include some of the only
known surviving copies of
Biblical documents made
before 100 C.E., and
preserve evidence of
considerable diversity of
belief and practice within late
Second Temple

Judaism.

Basically the dead sea scrolls are some of the
earliest written stories that are now in the
modern day bible. The bible itself is just a
compilation of ancient beliefs and stories
about the origins or god, humanity, good and
evil, Judaism, and eventually Christianity.


Newspapers


Sometime in the 13th century, paper money and playing cards from China
reached the West. They were "block
-
printed," that is, characters or pictures
were carved into a wooden block, inked, and then transferred to paper. Since
each word, phrase or picture was on a separate block, this method of
reproduction was expensive and time
-
consuming.


The first newspaper appeared in Boston in 1690, entitled
Publick Occurrences
.
Published without authority, it was immediately suppressed, its publisher
arrested, and all copies were destroyed. The first successful newspaper was the

Boston News
-
Letter,

begun by postmaster John Campbell in 1704. Although it
was heavily subsidized by the colonial government it enjoyed a very limited
circulation.

Printing Press


So basically people would compile as much current information
as possible into a written text. Etch the original copy onto some
sort of tablet and put into a printing press to be reproduced
over and over.


Morris Code


Although newspapers became widely popular as governments
became less powerful the information was most often old since
the speed of communication was only as fast as people could
walk or ride a horse to deliver information. People in other
tows would often revive information weeks even months after
events actually happened.




So people began looking for a quicker method for delivering
information.


Electricity was already being used as a massive scale in the
1800

s so that technology was already available. Electric lines
most often ran along side railroads since these rails naturally
ran to other town and cities.

Morris Code


Beginning in 1836,
Samuel F. B. Morse

and
Alfred Vail

developed an
electric telegraph
, which sent pulses of electrical
current to control an electromagnet that was located at the
receiving end of the telegraph wire.


Now information
could travel
instantly
between any
distance as long
as there was a
eclectic line
between the two
spots

Wireless Morris code and
Radio


However, morris code could only travel
as long as the lines would allow.


People now wanted a way to transmit
information wirelessly over large
distances including water.



Radio


the late 19th century it was clear to various scientists and
experimenters that wireless communication was possible.
Various theoretical and experimental innovations led to the
development of radio and the communication system we know
today. Some early work was done by
local effects

and
experiments

of
electromagnetic induction
. Many understood
that there was nothing similar to the "
ethereal

telegraphy"
[2]
[3]

and
telegraphy by induction
; the phenomena being wholly
distinct. Wireless telegraphy was beginning to take hold and
the practice of transmitting messages without wires was being
developed. Many people worked on developing the devices
and improvements.
