The million-dollar invention that we all have at home and that revolutionized the way we communicate in the world

With technology advancing by leaps and bounds, millions of people around the world They are connected in ways unthinkable decades ago. Since its invention, the television It is a key means of bringing people together, allowing news, culture and entertainment to be shared regardless of distance.

This revolutionary device became a must-have in homes, changing the way the world is perceived and establishing a direct channel to transmit ideas and emotions in real time. Television not only redefined the concept of entertainment, but also cemented its place in history as one of the most important inventions in science and technology.

How television was invented

The history of television begins in 1884, when the German engineer Paul Nipkow created a metal disk that could project images using light and selenium sheets. Although rudimentary, this system was the basis of television technology, marking the beginning of a medium that would revolutionize visual communication in the 20th century.

Then, in 1925, the Scottish John Logie Baird He perfected Nipkow’s invention by synchronizing two disks and transmitting the image of a mannequin at 14 frames per second. The following year, Baird showed his creation to the Royal Institution of London, and in 1927 he managed to send an image transmission over 700 kilometers using telephone cables, a milestone in distance communication. Later, he took this transmission from London to New York using Hertz waves.

Television was not only a technical novelty; It also acquired a specific name. It was the Russian scientist Constantin Perskyi who coined the term “television“in the first International Electricity Congress. At that time, the first devices were composed of radios and a neon tube behind the Nipkow disk, generating images the size of a stamp, although these were improved with new technologies in the following years.

In 1931, the Russian Vladimir Zvorykin presented the iconoscopean electronic tube that allowed the quality of the images to be considerably improved. This advance was key to the creation of electronic television, which resulted in unprecedented resolution and speed at the time. The system was improved by the German company Telefunken through the use of cathode ray tubes, which promoted the electric television in the 1930s.

By 1927, the BBC in it United Kingdom began the first programming transmissions, and in 1930 they were already able to synchronize audio and image in black and white. Germany had its first channel in 1931, followed by regular broadcasts in France in 1932. In England, this development came in 1936 and to the United States in 1939, cementing television as a global phenomenon.

Finally, in 1940, the Mexican engineer Guillermo González Camarena developed a color television system that was patented in United States and Mexicowhile the American Peter Goldmark Iimplemented a color system for Columbia Broadcasting System in 1948. In the 1950s, countries opened their television channels and television became established in homes, marking the beginning of a new era.

Approximately how many televisions are there in the world

Currently, it is estimated that there are more than 1.5 billion televisions in the world, which reflects the impact and permanence of this medium in daily life. As a recent study noted, “TV remains the center of entertainment in millions of homes, constantly adapting to new technologies and content platforms.”
