| 0:00.0 | The original telegraph system was based on ancient signaling systems utilized by many civilizations throughout history, |
| 0:21.6 | all of which allowed one person to communicate with another person, across large, sometimes even quite vast, distances. |
| 0:28.6 | In some cases this meant using drums or horns or other audible mechanisms. |
| 0:34.6 | Other times it meant flags of various colors and shapes to signal a general, for instance, |
| 0:40.1 | that reinforcements are needed at a particular location on a battlefield, or for a ship to notify |
| 0:45.8 | another ship that they wish to parlay, to have a friendly discussion rather than fighting each other. |
| 0:51.7 | At times, these mechanisms would extend into human-driven networks, |
| 0:56.4 | with one flag-bearer signaling another flag-bearer, who would raise their own flag after seeing |
| 1:01.4 | the first flag to signal yet another flag-bearer further along the path, and on and on and on, |

| 1:18.9 | This mechanism was improved upon by the aforementioned telegraph system, which formalized |
| 1:23.6 | the often flag or horn or other simple message transmitting system into a network of towers |
| 1:29.6 | that could transmit textual information from tower to tower across vast distances, |
| 1:35.6 | using a simplified alphabet communicated using a custom semaphore system, |
