History of communication

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. Communication can range from very subtle processes of exchange, to full conversations and mass communication. The history of communication itself can be traced back since the origin of speech circa 100,000 BCE. The use of technology in communication may be considered since the first use of symbols about 30,000 years BCE. Among the symbols used, there are cave paintings, petroglyphs, pictograms and ideograms. Writing was a major innovation, as well as printing technology and, more recently, telecommunications and the Internet. Human communication was initiated with the origin of speech approximately 100,000 BCE. 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 communications, 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. The oldest known symbols created for communication were cave paintings, a form of rock art, dating to the Upper Paleolithic age. The oldest known cave painting is located within Chauvet Cave, dated to around 30,000 BC. These paintings contained increasing amounts of information: people may have created the first calendar as far back as 15,000 years ago. The connection between drawing and writing is further shown by linguistics: in Ancient Egypt and Ancient Greece the concepts and words of drawing and writing were the same (Egyptian: 's-sh', Greek: 'graphein'). The next advancement in the history of communications came with the production of petroglyphs, carvings into a rock surface. It took about 20,000 years for Homo sapiens to move from the first cave paintings to the first petroglyphs, which are dated to approximately the Neolithic and late Upper Paleolithic boundary, about 10,000 to 12,000 years ago.
