3500 BCE
The invention of writing in 3,500 years B.C.
the Sumerians began to write their language using pictograms, which represented words and objects, but not abstract concepts. A sample of this stage can be seen on the Kish tablet.I chose writing as the first important thing in telecommunications because it is the beginning of communication. -
1184 BCE
invention of fire signals
In 1184 he invented what allowed to transmit letters, based on his famous "Square of Polybius": a code in which each letter of the alphabet is replaced by the coordinates of its current position. -

invention of the decimal system
Its power is based on the two fundamental properties that characterize it: the positional principle, by virtue of which the value of a certain figure depends on the position it occupies, and the existence of the concept of zero, as an indicator of nothing. -

use of homing pigeons
In Greek times, homing pigeons were used to broadcast the winners of the Olympic games. Hannibal and Genghis Khan used these birds to communicate with their armies (200 BC and 1200 AD, respectively). -
1440
the invention of the printing press
Johannes Gutenberg was considered the Father of Printing. It is in an old cloth factory where he began to develop the technique of lithography and where he would write his first texts with his printing press. -
The Telegraph
The most prominent prototype was the one designed by Samuel Morse, which consisted of a code that assigned each letter of the alphabet a number of dots and lines. This system allowed to increase the transmission speed. -
The phone
The first prototype was built by Antonio Meucci, although he did not formalize his patent due to financial difficulties. In 1876 Alexander Graham Bell was the first to formally patent it, and for many years, together with Elisha Gray, they were considered the inventors of the telephone. -
The typewriter
The first truly commercially successful typewriter was invented in 1872 by Christopher Sholes, Carlos Glidden, and Samuel W. Soulé. Sholes soon caught on with the machine and people started using it and even recommending it. -
Radio
Many consider Nikola Tesla the true inventor of the radio, although it was Guglielmo Marconi who filed the patent in 1904. He managed to send the first wireless communication in 1897. -
Television
John Logie Baird managed to convey a recognizable human face and in 1926, moving images. Two years later, he founded the Baird Television Development Company, broadcast from London to Glasgow, and showed the first color television set. In 1928 he broadcast from London to NY and, a year later, a German company asked him to develop a television broadcasting service. -
The computer
In 1941 the German engineer Konrad Zuse presented the Z3 the first digital computer. The first versions, still imperfect, Z1 (1938) and Z2 (1940) were assembled in his parents' house and thanks to the financial support of friends. The Z3 is considered one of the first programmable and automatic machines that could efficiently perform addition, subtraction, multiplication, division, taking the square root and managing memory. -
artificial intelligence
In 1950 Turing consolidated the field of artificial intelligence with his article Computing Machinery and Intelligence, in which he proposed a concrete test to determine whether a machine was intelligent or not, his famous Turing Test for what is considered the father of the Artificial intelligence. -
invention of the internet
The beginnings of the Internet take us to the 1960s. In the middle of the Cold War, the United States created an exclusively military network, with the aim that, in the hypothetical case of a Russian attack, military information could be accessed from anywhere country point. This network was created in 1969 and was called the ARPANET. -
ARPANET
ARPANET was a computer network created on behalf of the United States Department of Defense (DOD) to be used as a means of communication between different academic and state institutions.I chose this as the last one because a communications network is established in the United States. It seems important to me.
