The history of communication technologies (media and appropriate inscription tools) have evolved in tandem with shifts in political and economic systems, and by extension, systems of power.

Symbols were developed about 30,000 years ago. The imperfection of speech allowed easier dissemination of ideas and eventually resulted in the creation of new forms of communication, improving both the range at which people could communicate and the longevity of the information. All of those inventions were based on the key concept of the symbol.

Storytelling
Verbal communication is one of the earliest forms of human communication, the oral tradition of storytelling has dated back to various times in history. The development of communication in its oral form can be based on certain historical periods. Oral history is the method of collecting and preserving primary source testimonies from individuals and groups who lived through those time periods. The complexity of oral communication has always been reflective based on the circumstance of the time period. Verbal communication was never bound to one specific area, instead, it had and continues to be a globally shared tradition of communication. People communicated through song, poems, and chants, as some examples. People would gather in groups and pass down stories, myths, and history. Oral poets from Indo-European regions were known as "weavers of words" for their mastery over the spoken word and ability to tell stories. Nomadic people also had oral traditions that they used to tell stories of the history of their people to pass them on to the next generation.
Nomadic tribes have been the torch bearers of oral storytelling. Nomads of Arabia are one example of the many nomadic tribes that have continued through history to use oral storytelling as a tool to tell their histories and the story of their people. Due to the nature of nomadic life, these individuals were often left without architecture and possessions to call their own, and often left little to no traces of themselves. The richness of the nomadic life and culture is preserved by early Muslim scholars who collect the poems and stories that are handed down from generation to generation. Poems created by these Arabic nomads are passed down by specialists known as
sha'ir
A ''sha'ir'' () was a pre-Islamic Arab poet believed to have magical powers.
History
The origin of the term ''sha'ir'' is unknown. The ancient Arab culture viewed the ''sha'ir'' as a type of wizard, able to commune with supernatural forces, or ...
. These individuals spread the stories and histories of these nomadic tribes, and often in times of war, would strengthen morale within members of given tribes through these stories. Another example of this nomadic lifestyle where the people had no possessions but only passed on stories were the Waldensians, who passed along the word of God to anyone who would listen.
In its natural form, oral communication was, and has continued to be, one of the best ways for humans to spread their message, history, and traditions to the world. Now, oral history is used to collect people’s life testimonies and experiences, and is used to recover the voices that were once absent from history. It is not meant to capture past events, but it’s meant to reveal the origin of the memories.
Petroglyphs

The next advancement in the history of communications came with the production of

Scholars agree that there is a relationship between the West-Semitic alphabet and the creation of the Greek alphabet. There is debate between scholars regarding the earliest uses of the Greek alphabet because of the changes that were made to create the Greek alphabet.
The Greek alphabet had the following characteristics:
# The Greek lettering we know of today traces back to the eighth century BCE
# Early Greek scripts used the twenty-two West-Semitic letters and included five supplementary letters.
# Early Greek was not uniform in structure, and had many local variations.
# The Greek lettering was written using a lapidary style of writing.
# Greek was written in a

style.
Scholars believe that at one point in time, early Greek scripts were very close to the West-Semitic alphabet. Over time, the changes that were made to the Greek alphabet were introduced as a result of the need for the Greeks to find a better way to express their spoken language in a more accurate way.

Urban Communication
The study of Urban Communication is an interdisciplinary field that examines how communication is shaped by urban life and addresses the urban city experience with cities as communicative environments. Urban communication views cities themselves as complex communicative spaces where the surrounding environment, infrastructure, and communities the citizens create are means of exchanging or carrying messages and interpersonal interactions.
It also accounts for modern digital media such as smartphones or the internet becoming increasingly popular since the 1990s and early 2000s, which allows for accessible, real-time exchanges between individuals and groups who want to give and receive information in industrialized countries.

Morse Code
Morse Code was invented by Samuel F. B. Morse, who originally built telegraph lines in 1837. The telegraph is considered to be of the most revolutionary inventions in regards to telecommunication history with its use in World War 2. Morse Code has a symbiotic relationship with the telegraph because the invention of the code allowed for the creation of messages, and the telegraph was able to transmit the message.
Morse code is operated by using telegraph keys as the transmitter device, while the operator sends out the dots as signals combined sequentially with the dashes as longer signals. On the receiving end, the receiving device would make a clicking noise that the operator would transcribe.
