the development of telephones‚ television‚ and many other electronic based devices. Telegrams were sent to communicate transversely throughout the world and forever changed the way electricity was used. Before this invention‚ a simple letter or semaphore would have to suffice. In the 1830’s‚ the telegraph was first invented. The telegraph had high expectations as it was invented to communicate to help railroad signaling in Britain. (Morse Code and the Telegraph).

The history of telecommunication began with the use of smoke signals and drums in Africa‚ theAmericas and parts of Asia. In the 1790s the first fixed semaphore systems emerged in Europe; however it was not until the 1830s that electrical telecommunication systems started to appear. This article details the history of telecommunication and the individuals who helped make telecommunication systems what they are today. The history of telecommunication is an important part of the largerhistory of communication

signaling devices‚ both mechanical and automated‚ were patented by various inventors. Of these‚ only a few saw production or implementation on public roads. Morgan’s device first patented in 1923‚ was a hand-cranked‚ manually operated mechanical semaphore signal.[7] His device had two key safety features: having an intermediate "all stop" signal state to give moving traffic time to stop before signaling cross traffic to proceed‚ and having a "half mast" position to indicate general caution at times

The invention and creation of Morse Code changed the history of United States forever. “Invented by Samuel Morse in 1832. The idea was sparked on his trip back to the United States from Europe. A passenger asked how fast electricity would travel through a wire tightly wrapped around a magnet” (Zannos 24). This invention made long distance communication easy and convenient for all people. It also connected World Leaders to allies and spies and made the world a more connected place. Mr. Morse’s contributions
