The television is a type of system through which the images can be transmitted to equal the sound through a type of wave called Hercynian, or through networks specialized in the case of cable television. Invented at the beginning of the 20th century as a way of providing education and communication , it became in the middle of the century one of the most important means of disseminating information and bringing entertainment to millions of homes around the world.

Background
One of his main background was without a doubt the cinema and photography , means by which it was possible to put into motion the images and also shape them using techniques that gradually were improved. By the end of the 19th century, it had already been achieved that moving images could be captured and reproduced through a series of photos that occurred at a constant speed.
Origin of television
The origin of television began when, thanks to Paul Nipkow , the disc that bears his name was invented , which led to the advancement of the device. The invention of the iconoscope by Vladimir Szorykin and Philo Taylor Farnsworth, managed to manufacture a type of electronic television which gave a better image with its own lighting.
Evolution
The evolution of television has been very diverse and many steps were taken to achieve what we enjoy today. Many developments were presented starting with the Baird television , a device created in 1920 by John Logie Baird , who devised something very similar to current televisions but with the difference that it was not electrical and on the contrary, it had a mechanical component . It was a very large box, and it also had a considerably small screen.
In 1930 the first electronic television was created which was in black and white, its size also increased as well as its screen. Little by little, technology was increasing and by the end of 1948, a model began to be commercialized in search of the economic recovery that the war had left.
In 1950 , the first RCA 21 television model emerged , a model that marked a major change in the television industry and manufacturing as they laid the foundations for today’s televisions. Subsequently, a system was created whereby colors could be introduced into the apparatus using a type of sequential trichromatic system, and in 1960 the transmission was completely switched from black and white to color transmission .
The television with cathode ray tubes came to completely improve the television, the size of the screen increased even more and it was possible to obtain resolutions with a greater number of pixels , one of the most important steps in the evolution of the device. The plasma TVs began to be built, with flat screens and ability to emanate larger amounts of color by the definition of the images was even better. The use of fluorescent lamps also reached the television and that is how LCDs emerged , devices that had better lighting and were made with liquid crystal to increase production and production.color quality . LED screen televisions are the most modern and have a more uniform light, are environmentally friendly and are also mercury- free . Finally, the Smart TV arrived on the market , the latest in technology that can even be connected through Wi – Fi networks, also allowing the use of many current applications.
Present
Today, television faces one of its greatest enemies, the internet . Despite the fact that over time the devices have evolved significantly, the digitization process and the appearance of new forms of information have left the audiovisual reality relegated to one side. Despite this, television remains the favorite medium for many to entertain themselves and find reliable sources.
One of the main reasons why television has begun to be relegated to the background is the possibility that the user has of being able to find what he needs at the precise moment through wireless networks , a situation that does not occur with the regular television, as it is completely dependent on channels to find relevant programs. Currently, a person has the ability to watch series , movies and children’s programs without the need for a television, it does not take more than a cell phone or a computer to be able to find everything you want, and this situation has weakened the trade and manufacture of televisions.
Stages in television history
Television has gone through a series of stages to reach what is known today. One of its first stages occurred in the 30s and 50s when the first televisions were created that transmitted black and white images through a cathode tube that illuminated the screen. In the 70s , what is considered the second stage occurs, at which time color was introduced to the device. A third stage appeared in the 80s when remote controls began to be created making it easier to pass channels to users. In the 90s , flat screen televisions appearedmaking television achieve a major boom. Finally, television improved remarkably thanks to the introduction of LCD televisions that displaced the traditional way of watching television.
Who invented it
The invention of television is attributed to the British John Logie Baird who did many studies at the University of Glasgow and the Technical School of the place. In 1922, he began to show his research regarding the ability to transmit images at a distance . He filed his patent in 1923, on June 26, and consisted of a system for transmitting views, photos and scenes by means of wireless telegraphy.
Importance
Its main importance is that since its invention, television has been one of the most important mechanisms through which relevant information can be transmitted , mainly thanks to the access that millions of people have to television sets. It is a way of communicating to viewers what is happening in other places and thus keeping them informed . In addition, it turns out to be one of the best means of obtaining entertainment , education and knowledge on various current and ancient topics.
It also addresses the different types of interests that both the people who observe it and the companies that build them have, since they are also an important economic source for many. Television occupies a very important place within families as it also offers company to many people throughout the day and also produces a series of positive feelings that lift the spirits.
