    The telegraph was one of the most revolutionary inventions of communications, since it allowed long-distance communication instantly. It was invented by Samuel Finley Beese Morse

  • Telephone

    Telephone
    It was invented by Antonio Meucci to communicate with his sick wife. It permits two or more users to conduct a conversation when they are too far apart to be heard directly. A few years later, in 1876, Alexander Graham Bell was the first to formally patent it.

  • Radio

    Radio
    Nikola Tesla is considered by many to be the true inventor of the radio, although it was Guillermo Marconi who filed the patent in 1904.
    Marconi used Tesla's invention in 1899 to make the first wireless communication. He sent a message between Dover (England) and Boulougne (France), at a distance of 48km.
    The first radio broadcast in history took place on Christmas Eve 1906, when the song "Oh Holy Night" and some verses from the Bible could be heard from Brant Rock Station (Massachusetts).

  • Television

    Television was invented by John Logie Baird in 1923 in Hastings, England. The first television picture was broadcast by Baird in 1926.
    In the early 1930s, television began to be sold as electronic products and began to attract a wide audience.

  • Computer

    In 1941, Konrad Zuse was the first to build a working computer. He did it in the living room of his parents' house in Berlin. This computer could store 64 words.

  • Tablet

    Tablet
    The first examples of the "information tablet" concept were shown in the 2001 film A Space Odyssey (from 1968). Probably based on these fictional tablets, Alan Kay developed the Dynabook tablet concept (in 1972), although the technology of the time did not allow him to build a functional device.
    The first true devices only appeared in the early 21st century when Microsoft launched the Microsoft Tablet PC.
    In 2010, Apple introduced the iPad, its own tablet, and they achieved commercial success.

  • Mobile Phone

    Mobile Phone
    It was invented by Martin Cooper.
    At first the mobile phone could only be used in vehicles due to its large size, later being reduced to a portable unit, and finally to the pocket size that is used today.
    On April 3, 1973, Martin Cooper made the first call from a DynaTAC 8000X project mobile phone from a New York street.
