In the beginning was the Word. In the beginning information passed from one person to others through speech. Oral tradition was the only means of distributing information until the advent of visual communication, and continued for some time to be the primary means of sharing and preserving information. Cave paintings are usually recognized as the earliest form of visual communication, with the earliest known dating to 30,000 BC. More permanent visuals — carvings rather than paintings — developed shortly thereafter, with pictograms (the predecessor to hieroglyphics and cuneiform) developing by around 9000 BC.
