Present days we are witnesses of revolution in all directions, but one has its own magnificence and beauty, we call it just television. From its creation until now, it undergoes many changes as well as improvements. There are three main events in the history of the television, and in the few sections below, I will introduce each one of them separately.
The first event was its invention in the far away 1927, when after that in 1932 was also the first broadcasted TV signal on the planet. For ordinary people this looks not so fantastical or majestic, but there is no doubt that was one huge boom in world sizes. To be frank, I also maintained that when the television was black and white and it was possible only by air is something marginal, but after little examination that I made my thinking go in other direction. Even then, the technology has been brilliant and very complex, because first to catch and upload one picture is very difficult, then what about when we must reproduce this but with moving object. Despite those facts, after that the signal had to be transmitted in one direction but on big distance. How could it be possible? The answer is simple but it consisted in it a lot of information, for me and for those who aren't supposed to know; modulation, this happening, or physical law or just a process, is the main manner that helped the possible watching of TV at any time of the day. Yes, if we juxtapose adjacent to each other, HD and analogue TV, we will see enormous subtract in the quality between those two technologies. However, in the end, the point is without the so-called "simple", "mere" or "elementary" analogue signal, what we know now, wouldn't be possible.
Second, the transformation, or just the appearing of one more player in the game, called cable TV also played a big role in television history. I think I am missing something named Satellite TV, one of the other great inventions, which was related first in other researches, but telecommunications have many headings. As a matter of fact the converted from analogue to digital signal was the huge discovery in broadcasting it.
Last but not least, is the creation of the HD format. For those who don't know, here the signal again is digital, but with improved quality, more data, more reliable codes, procedures and techniques. Nowadays, this is the unique advance of this sphere, because HDTV offers something so realistic, that what is seen on the screen can coincide 100 % with what is outside the window, something truly astounding.
