Writing
The writing allowed space-time independence between the
sender and receiver, and the accumulation and preservation of knowledge and information for posterity. However, it was slower, more elitist and less dynamic. https://www.bbc.com/mundo/noticias-39781154 -

Postal Courier
The first documented use of an organized courier service was found in Egypt in 2400 B.C. -

Visual and acoustic signals
The first technologies used in communication used visual signals such as beacons or smoke signals, or acoustic signals such as through the use of drums or horns. En torno al 1000 a. C., se comunicó a la ciudad de Argos la victoria sobre Troya mediante estaciones repetidoras que eran capaces de transmitir en una noche. https://www.youtube.com/watch?v=8Ex-yK3WKhw -

Hydraulic telegraph
he sender alerted the receiver with torches the moment in which both had to open and close the water, so that the water level indicated which message on the board was to be transmitted. -

Printing press
Invented in the Holy Roman Empire by the German Johannes Gutenberg around 1440, based on existing screw presses. The printing press allowed a real revolution
in the dissemination of knowledge making it accessible to all and eliminating its elitist character. https://www.uv.es/bellochc/pdf/pwtic2.pdf -
Leibniz calculator
The Leibniz Universal Calculator not only added and subtracted, but could also multiply and divide. -
Electric Telegraph
An electrical telegraph is a telegraph that uses electrical signals, usually conveyed via dedicated telecommunication lines or radio. In the United States, the Morse/Vail telegraph was quickly deployed in the two decades following the first demonstration. The overland telegraph connected the west coast of the continent to the east coast by 24 October 1861, bringing an end to the Pony Express. -
Morse Code
Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. It is named for Samuel F. B. Morse, an inventor of the telegraph. Beginning in 1836, the American artist Samuel F. B. Morse, the American physicist Joseph Henry, and Alfred Vail developed an electrical telegraph system. -
Telephone
Antonio Meucci, the true inventor, used it to connect his room with the office. Graham Bell was the first in making it massive. -
The radio
The inventor of the radio is Guillermo Marconi in 1896. This electrical engineer born in Italy, would be the first to find Hertz's theories a practical application. There was already a form of communication between points far away not only thanks to the telegraph and the telephone, but always using cables, terrestrial or underwater. But the cable did not always reach where it was needed. Together with television, it has been the most important mass media of the last century. -
TV
Baird gave the first public demonstration of the operation of a television system to members of the Royal Institution and a journalist on January 26, 1926 in his London laboratory. In 1927, Baird transmitted a signal at 438 miles through a telephone line between London and Glasgow. -

Fiber Optics
In 1952, physicist Narinder Singh Kapany, relying on John Tyndall's studies, conducted experiments that led to the invention of fiber optics. One of the first uses of fiber optics was to use a fiber bundle for image transmission, which was used in the endoscope. -
Internet
ARPANET was a computer network created by order of the United States Department of Defense (DOD) to use it as a means of communication between different academic and state institutions. The first node was created at the University of California, The Internet has revolutionized communications, as the telegraph, radio or telephone did in its time. Internet has become a necessary tool for worldwide communication. -
Cell phone
On April 3, 1973, Martin Cooper, Motorola's manager, made the first call from a DynaTAC 8000X mobile phone from a New York street. Precisely to its biggest rival in the telephony sector: Joel Engel, of the Bell Labs of AT&T. Although in the 40s the equipment occupied the entire trunk, in the 60s its size had been reduced to that of a briefcase. The mobile phone or cell phone is an indispensable device today; However, its popularization has been a very recent phenomenon. -
Laptop
The first laptop was the Epson HX-20 developed in 1981. It demonstrated its great benefits for the work of scientists, military, businessmen, and other professionals, who saw the advantage of being able to take their computer with them with all the information they needed from From one place to another. -
Mouse
On April 27, 1981, the first included mouse computer was launched: Xerox Star 8010, essential for the new and powerful graphical interface that depended on this peripheral, which was also another revolution. -
Smartphone
The computing power of a smartphone is comparable to that of a desktop or laptop computer. The first smartphone in history was the IBM Simon, made in 1992. -
Social networks
1997 is the year that SixDegrees was created, the first site in the history of social networks, a site that is still open today. This site focuses on the fact that any person is only six steps away, social circles, from the person most distant from them and that we are always connected. Although it has been considered that this website failed commercially in its first launch, it laid the foundation for what we know today as social networks. -
WIFI
In April 2000, WECA certified the interoperability of equipment according to the IEEE 802.11b standard, under the Wi-Fi brand. It is a technology that allows the wireless interconnection of electronic devices. Wi-Fi enabled devices can connect to each other or to the Internet through a wireless network access point. -
AI
In 2018, some residents of Phoenix (Arizona) can already download an app to call an autonomous taxi, Alpha Zero teaches itself to play chess, and in Spain an AI called Veripol is launched to detect false complaints. In January 2019, almost 300 papers aimed at artificial intelligence were registered in arXiV, a repository of studies. And they keep increasing.
