Timeline of Communication Systems: Introduction |
 |
The timeline of communication systems presents a chronological overview of the most important events in the history of communication systems from the 4th millennium B.C. to the present.
It shows that from the very beginning - the first Sumerian pictographs on clay tablets to today's state-of-the-art technologies - broadband communication via  fiber-optic cables and satellites - the amount of information collected, processed and stored, the capabilities to do so, as well as the capable speed of information transmission exponentially accelerate.
