![]() ![]() The idea came from British admiral Phillip Colomb, who used the signal lamp design of Arthur C.W. This project was met with setbacks before it was completed in August 1858.ġ867: Dots and dashes were flashed with signal lamps for the first time at sea in 1867. This was known as Morse code.ġ858: Cyrus Field sought to lay the first transatlantic telephone cable, connecting England and the U.S. Morse discovered that you could transmit messages by pressing down or releasing a button in intervals to transmit a pattern of sounds. Very much like the two-soup-can toys you made as a child, Hooke found that sound could be sent over a wire or string from a mouthpiece on one side to an earpiece on the other.ġ838: Samuel B. The history of the telephone is an amazing timeline of experimentation and discovery.ġ672: Robert Hooke created the first acoustic telephone in 1672. We can convey important information quickly and efficiently, and now, with cell phones and smartphones, we can send important data, capture memories, and explore the Internet, all from our mobile phone. With it, we've connected over mountains, across oceans, and to opposite ends of the world. The company RCA was the one to create standard colored TVs across all of America.One of the greatest innovations in communication technology to date is the telephone. The idea was patented in 1904, but it was not until 1946 that it became a reality. An investor asked the young man when they were going to see some dollars from this invention and it was at this point that the young scientists transmitted a dollar sign on his TV prototype. He succeeded as he also used the cathode ray tube invention from his predecessors. He wanted to transmit the images in the form of a code via radio waves. He combined principles of the radio and the telephone to make the transmission of the images efficient. In 1927, the first electric television was created by a young 21-year-old called Philio Taylor Farnsworth. A Campbell and Boris Rosing combined a cathode ray tube with the mechanical scanning system of the mechanical televisions to create a prototype of the electric television. In 1907, the fundamentals of modern television were created. These were inefficient and not very practical. They scanned images onto a rotating disc structure and then transmitted this information onto another television. The first TVs were called mechanical televisions. Television has come a long way since its first versions. Amplitude and frequency are 2 physical properties that define the properties of a wave. The first one allows for better sound manipulation. FM radio waves change the frequency of the waves, vs AM waves change the amplitude of the waves. It was in 1960 that there was the discovery of FM radio waves, which made the signals more clear and with better quality. ![]() Radio was used throughout various countries and for various purposes such as entertainment and news. In 1922, Marconi created the first radio station In the UK, the BBC. The invention of the radio was patented to Gugliemo Marconi and it merely transmitted morse code messages. The radio began in 1893, with Nicola Tesla, demonstrating wireless radio message transfer in St. In 1927, we had the first transatlantic phone call, between the USA and UK. The telephone had become publicly available. At this point, there were various companies established that were focused on providing this service. Then, in 1915, we had the first call from coast to coast of the USA. The first telephone used the infrastructure set in place by the telegraph and Alexander Graham Bell made his first telephone call using the telegraphic network of Ontario and made a call over an 8-mile distance. This was built upon previous discoveries of the Morse code, the telegraph, and then the wireless telegraph. The telephone was patented by Alexander Graham Bell in 1876. ![]() These inventions build on top of each other and the improvement of multiple technologies allowed for the creation of the television. They allow for fast and efficient long-distance communication. The radio, telephone, and television are mass media communication tools. ![]()
