Communication History

The history of communication begins before Humans.  But, let’s start with humans anyway.

Let’s just start with the concept of “Symbols.”  For the purposes of this discussion, communication is defined as the movement of some intent from a sender to a receiver.  Symbols, a shared representation of a thing, were the first communication invention. Once we had a “symbolic” way to represent things and ideas, we were able to stimulate other inventions and cultural improvements.  Eventually we invented all sorts of new ways to communicate that allowed for an increase is the distance we could communicate, the longevity of the information being communicated, and the amount of information that could be communicated.


Cave Painting – 20,000 +/- years ago

I want to start with Cave Painting.

Cave paintings are paintings and drawings found on cave walls and ceilings.

One of the earliest is thought to be approximately 40,000 years ago, and is in the El Castillo cave in Cantabria, Spain.

The exact purpose of these paintings is clearly up for debate.  But, an interesting fact is that they are often found in areas that do not have evidence of ongoing habitation.  And are also often located in areas of caves that are not easily accessible.

My uneducated guess is that there are probably a lot of different reasons why people would go through the effort to do these things.  Just as there are a lot of different reasons for the different paintings exhibited in the Louvre.  Some paintings could have been used for training the next generation of hunters (an early whiteboard).  Some paintings could have been the artist experimenting with this new art form.  Some paintings could have been for the artists ego, saying look how great I am I can do this thing.  And some could have been simply because an artists could and did.

One of the most important advantages of cave paintings over speech is that it allows for the sender of the communication and the receiver of the communication  to be separated by time.  Before cave paintings all communication existed only for the instant that the sender created the communication.  But after, a teacher could teach the same lesson on how to dill a animal the next day, the next week, or the next century.

But, while, the advantage of allowing for separation of the sender and receiver by time, it had a huge disadvantage.  A cave painting does not move.  So, a cave painting could not separate the sender and receiver by location.  The message did not move, the communicators had to move.

Another important aspect of cave paintings is that it removed memory form the communication process.  Up until Cave Paintings all forms of communications relied on human memory.  And as we have all personally experienced, memory is an imperfect tool: memory can become corrupted or lost over time, and there is a limit to how much one can remember. With the accidental death of a ‘wise man’ or tribal elder, a pre-literate tribe could lose many generations of knowledge.


Pictograms and Clay, Wax, and Stone Tablets – 8500 BCE to 1000 BCE

A pictogram (pictograph) is a symbol representing a concept, object, activity, place or event by illustration.

Pictography is a form of proto-writing whereby ideas are transmitted through drawing. Pictographs were the next step in the evolution of communication.

The big advance of pictography and clay, stone or wax tablets is that the sender and the receiver could be separated by distance as well as by time.  Also, one could collect, store, and retrieve these tablets. Thus libraries were born.



Alphabet, Papyrus, and Paper – 2000 BCE to today

The invention of inks and papyrus and paper roughly happened around the same time. One of the oldest pieces of writing on papyrus known to us today is the Egyptian “Prisse Papyrus” which dates back to 2000 B.C.  105 BC Tsai Lun of China invents paper as we know it.

The huge advantage of using an alphabet and paper was the quantity of information a communication could contain.  Pictographs and tablets were limited in how much information they could communicate.  But, this new invention changed all that by orders of magnitude (or something like that.)

Though papayas and paper were not as durable as clay or stone, the net benefits far outweighed (no pun intended) the disadvantages.

One of my favorite examples of writing in this period is the Torah.



Moveable Type (The Printing Press) – 14th Century to today

The next huge leap in Communication was the use of moveable type which begat the Printing Press.

From Wikipeda

Movable type is the system of printing and typography that uses movable components to reproduce the elements of a document (usually individual letters or punctuation).

The world’s first known movable type system for printing was created in China around 1040 A.D. by Bi Sheng (990–1051) during the Song Dynasty;[1] When this technology spread to Korea during the Goryeo Dynasty in 1234, they made the metal movable-type system for printing. This led to the printing of the Jikji in 1377, the oldest extant movable metal print book. The diffusion of both movable-type systems was, however, limited:[2] They were expensive, and required an enormous amount of labour involved in manipulating the thousands of ceramic tablets, or in the case of Korea, metal tablets required for scripts based on the Chinese writing system, which have thousands of characters.

Around 1450, Johannes Gutenberg invented an improved movable type mechanical printing system in Europe, along with innovations in casting the type based on a matrix and hand mould. The more limited number of characters needed for European languages was an important factor.[3] Gutenberg was the first to create his type pieces from an alloy of lead, tin, and antimony—the same components still used today.[4]

Books and libraries existed before Moveable Type.  But, it was quantity and quality of the books and libraries after movable type that is notable.

I believe the Reformation and Age of Enlightenment are directly tied to the Printing Press.

Before the Printing Press, worshipers had to rely on the Church to tell them what is in the bible.  After the Printing Press people could go to the Bible themselves.  And scientists could study the work of other scientists directly from the original.

The Printing Press was the Internet of its day in terms of opening up publishing to the masses.

1450 Newspapers appear in Europe.
1455 Johannes Gutenberg invents a printing press with metal movable type.
