TELEVISION AND RADIO: AN AMAZING INVENTIONS

Television and radio are two amazing inventions for the comunication. Radio was the first invention with sounds and voice where people could talk about anything that happened in that moment, for this reason, radio used like a media since the begining of this invention. Television was the first invention with sounds, voice and the most important thing, with pictures, this invention could be the competition for the radio, at the begining that situation was in that form, but now radio is complementary to television about transmitting information.

Television was created by many people, among them is important to highlight the work of Paul Gottlieb Nipkow who invented the Nipkow disk. Accounts of its invention state that he conceived the idea of using a spiral-perforated disk to divide a picture into a mosaic of points and lines while sitting alone at home with an oil lamp on Christmas Eve, 1883. The first telecasts used an optical-mechanical picture scanning method, the method that Nipkow had helped create with his disk; he could claim some credit for the invention. On the other hand, we have to mention the work of John Logie Baird who was inventor of the world's first working television system.

Besides, the radio was created by many people too, people like Nikola Tesla, who in 1893, gave at St. Louis, Missouri a public demonstration of "wireless" radio communication, he described too the principles of radio communication, in that case, we can see that since the beigining radio was seen as a media, the answer to a need for the humanity. Another principal creator of the radio was Alexander Popov who performed a public demonstration of transmission and reception of radio waves used for communication at the Russian Physical and Chemical Society, using his coherer: this day has since been celebrated in Russia as "Radio Day".

In this time, the problem between radio and television isn’t clearly because now exist networks like Caracol and RCN, in that radio and television are booth of the same network, but now the competition is between channel and channel, network and network respectively. Moreover, the television and radio have had a technological changes in recent years, it makes people have more opportunity to access information and they can choose and they can choose where to log in. Sometimes, we can see that old people used so much the radio because they said: “if the radio said it is because it’s true”, and other kind of people prefer television because “A picture is worth a thousand words”

But, the point is that people who prefer watch TV and people who prefer listen to the radio can be change according to the resources that both of that media have to show to the public. WE can't say that TV or radio are better one of other, but we can say and decide by the media that provide better information and logically entertainment. Is our work help to the media will be better.
