TELEVISION
Origin, Landscape , Landsmark
and Future Directions
There is controversy surrounding the invention of one of the most popular 21st century devices: the Television. It took several decades for many inventors and engineers in various countries to develop the modern television.However; two important people whose names are associated with the invention of television are Vladimir Zworykin, and Philo Farnsworth.
Although prior to 1922, the concept of television was already in existence, it was primarily due to the efforts of these two people that the concept of electronic scanning of images, which forms the bases of modern day television, was introduced. Both Zworykin and Farnsworth had applied for the same patent during the year 1923 and 1927 respectively.
The fact that Zworykin had filed for the patent earlier, he is often termed as the father of television. Nonetheless, the work of Farnsworth cannot be underestimated. In fact, many believe that at least six of his basic patents are being utilized in the manufacture of modern day television.
On the same list, is John Logie Baird—a Scot living in England who is recognized as the first to demonstrate an operational television in March of 1925. Baird transmitted the first televised pictures of moving objects in 1924, the first televised human face in 1925, and the first real-time moving object in 1926. However, it was electronics inventor Philo Farnsworth who is credited with inventing the first completely electronic television.
The difficulty in deciding who invented the first television centers on the fact that there were several discoveries or inventions all of which were added up to make the complete TV set. Indeed, the historical development of the TV is a complex series of events, and proclaiming any one man as the sole TV set’s inventor seems inaccurate at best. For those who still ask, “What’s the answer to ‘Who invented TV’?” –there is no clear inventor, since there were several inventions created by different people that were merged to make the televisions we so dearly can’t live with today.
These landmarks by inventors, big thinkers, and pioneers have forever changed the way people communicate, learn, and interact with each other. These historical landmarks in television are a microcosm of how one idea spawns another. Looking at the past is a good indicator for future growth and development. There may be new inventions on the horizon that will make the television as obsolete as the typewriter. But one thing is for sure, the television and all the inventions before it will be the catalyst for whatever the next wave of electronic communication may be.
* 1831 – Electromagnetism “The Seed for Electronic Growth” Joseph Henry’s and Michael Faraday’s work with electromagnetism jumpstarts the era of electronic communication.It’s difficult to imagine the days before the realization of electromagnetism. Without this key understanding, there would be no television and many other devices that we use everyday. Electromagnetism was a seed in which an enormous tree grew. By far the most important ingredient in the invention of the television.
* 1862 – First Still Image Transferred, Abbe Giovanna Caselli invents his Pantelegraph and becomes the first person to transmit a still image over wires. To see the first ever electronic image must of been an exciting moment in time . After all, you have to walk before you can run. Soon, instead of a single image, there would be multiple images transported to create motion. The invention of the Pantelegraph by Abbe Giovanna Caselli was just the beginning of what was to come.
* 1900 – And We Call It “Television”, As it turns out, the name stuck! There has to be someone who comes up with the name. In this case, it was a Russian by the name of Constantin Persky at the World’s Fair in Paris where the first International Congress of Electricity was held.
* 1906 – First Mechanical Television System, Lee de Forest invents the Audion vacuum tube that proved essential to electronics. The Audion was the first tube with the ability to amplify signals. Boris Rosing combines Nipkow’s disk and a cathode ray tube and builds the first working mechanical TV system.
* 1927 – Long Distance Use of Television, Bell Telephone and the U.S. Department of Commerce conduct the first long distance use of television that took place between Washington D.C. and New York City on April 9th. Secretary of Commerce Herbert Hoover commented, “Today we have, in a sense, the transmission of sight for the first time in the world’s history. Human genius has now destroyed the impediment of distance in a new respect, and in a manner hitherto unknown.” Just like the transmission of the first electronic still image in 1862, this accomplishment of transmitting a log distant television signal must of been just as an exciting of a moment. To see someone from a far off place must of been like witnessing a teleportation.
* 1946 – Color, Peter Goldmark, working for CBS, demonstrated his color television system to the FCC. His system produced color pictures by having a red-blue-green wheel spin in front of a cathode ray tube. Let there be color!! Although it was still many years away from a main stream technology, adding color to television was like adding a light bulb to a room. Suddenly, viewers could see better.
* 1956 – Remote Control, Robert Adler invents the first practical remote control called the Zenith Space Commander. Control. Robert Adler’s invention of the modern day remote control for television paved the way for future control companies like Crestron.
* 1973 – Giant Screen Projection TV, Why go to the theater when you can have your own theater in your home? These were the infant days of home theater applications.
* 1996 – The FCC Taking about future directions of television, Future television will be a magician one. I think like that. Because world’s technology and knowledge of inventors are very improved. I hope to be able to carry a TV bag in the future. And I think the viewer will be able to capture the scenes we see live. Suppose we want a dress or a meal in a TV commercial. We may be able to take it off the screen immediately. Perhaps more advanced media that television has been created and television has become obsolete. ATSC’s HDTV Standard., Almost as important as color TV was the invention of HDTV. Suddenly, the sporting game looked crisper and better in your living room then it looked in person.

Taking about future directions of television I think television will definitely be an essential thing for human beings in the future. Future television will be a magician one. I think like that. Because world’s technology and knowledge of inventors are very improved. I hope to be able to carry a TV bag in the future. And I think the viewer will be able to capture the scenes we see live. Suppose we want a dress or a meal in a TV commercial. We may be able to take it off the screen immediately. Perhaps more advanced media that television has been created and television has become obsolete. And in the future, television will change all human behavior patterns.
