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 500,000 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.
