Communication Trends: Telegraphs to Smartphones

In ancient times, information was transmitted across long distances via drum beats or smoke signals; however, these methods were limited by the weather and the ability to see receptor points. In the early 1790s, the semaphore, a modern precursor to the electric telegraph, was developed. This solution consisted of a series of hilltop stations that used arms to signal letters and numbers, along with two telescopes used to see the other stations. Facing similar issues as previous methods, a different mode of transmitting data was needed for long-distance communication.
