As part of National Conversation Week, we take a look at some of the major milestones that have shaped the way we interact with one another.

Early Forms of Communication (40,000 BCE - 3,500 BCE)

Long before the invention of writing, early humans relied on simple yet effective means of communication to convey messages. Some of these early forms included:

Smoke Signals: As early as 200 BCE, civilisations like the Greeks and Chinese used smoke signals to transmit information over long distances.

Cave Paintings: Dating back to 40,000 years ago, cave paintings were among the first visual forms of communication, depicting scenes of hunting and rituals.

Drumming: In Africa, drums were used to send messages across vast distances. Different rhythms and patterns represented specific messages, allowing communities to stay connected.


Invention of Writing (3,500 BCE)

The development of writing systems marked a significant turning point in the history of communication. The Sumerians in Mesopotamia created the first known form of writing, called cuneiform, which allowed them to record transactions, laws, and stories for future generations.

Carrier Pigeons: Feathered Messengers (3000 BCE)

Carrier pigeons have played a significant role in long-distance communication since ancient times. As early as 3000 BCE, the Egyptians and later the Romans utilised these birds to deliver important messages across vast distances. Their remarkable ability to navigate back to their home, even when released hundreds of miles away, made them a reliable and discreet method of communication.


The Print Revolution (1440 CE)

The invention of the Gutenberg press in 1440 by Johannes Gutenberg transformed communication by enabling the mass production of books. This print revolution made written works more affordable and accessible, spreading knowledge and information throughout Europe and beyond.

Braille (1824)

In 1824, Louis Braille, a blind Frenchman, invented a tactile writing system for the visually impaired. Braille consists of raised dots that can be felt with the fingertips, allowing blind individuals to read and communicate more effectively.
