Lets Write about "Who Invented Television?" history
The way people watch television has changed dramatically since the medium first burst onto the scene in the 1940s and ‘50s and forever transformed American life.
Early TV Technology: Mechanical Spinning Discs
No single inventor deserves credit for the television. The idea was floating around long before the technology existed to make it happen, and many scientists and engineers made contributions that built on each other to eventually produce what we know as TV today.Television’s origins can be traced to the 1830s and ‘40s, when Samuel F.B. Morse developed the telegraph, the system of sending messages (translated into beeping sounds) along wires. Another important step forward came in 1876 in the form of Alexander Graham Bell’s telephone, which allowed the human voice to travel through wires over long distances.
Both Bell and Thomas Edison speculated about the possibility of telephone-like devices that could transmit images as well as sounds. But it was a German researcher who took the next important step toward developing the technology that made television possible. In 1884, Paul Nipkow came up with a system of sending images through wires via spinning discs. He called it the electric telescope, but it was essentially an early form of mechanical television.
TV Goes Electronic With Cathode Ray Tubes
In the early 1900s, both Russian physicist Boris Rosing and Scottish engineer Alan Archibald Campbell-Swinton worked independently to improve on Nipkow’s system by replacing the spinning discs with cathode ray tubes, a technology developed earlier by German physicist Karl Braun. A cathode ray tube is a vacuum tube that uses a stream of electrons to create images on a phosphorescent screen. Swinton’s system, which placed cathode ray tubes inside the camera that sent a picture, as well as inside the receiver, was essentially the earliest all-electronic television system.Russian-born engineer Vladimir Zworykin had worked as Rosing’s assistant before both of them emigrated following the Russian Revolution. In 1923, Zworykin was employed at the Pittsburgh-based manufacturing company Westinghouse when he applied for his first television patent, for the “Iconoscope,” which used cathode ray tubes to transmit images.
Meanwhile, Scottish engineer John Baird gave the world's first demonstration of true television before 50 scientists in central London in 1926. With his new invention, Baird formed the Baird Television Development Company, and in 1928 it achieved the first transatlantic television transmission between London and New York and the first transmission to a ship in the mid-Atlantic. Baird is also credited with giving the first demonstration of both color and stereoscopic television.
In 1929, Zworykin demonstrated his all-electronic television system at a convention of radio engineers. In the audience was David Sarnoff, an executive at Radio Corporation of America (RCA), the nation’s biggest communications company at the time. Born into a poor Jewish family in Minsk, Russia, Sarnoff had come to New York City as a child and began his career as a telegraph operator. He was actually on duty on the night of the Titanic disaster; although he likely didn’t—as he later claimed—coordinate distress messages sent to nearby ships, he did help disseminate the names of the survivors.
Sarnoff was among the earliest to see that television, like radio, had enormous potential as a medium for entertainment as well as communication. Named president of RCA in 1930, he hired Zworykin to develop and improve television technology for the company. Meanwhile, an American inventor named Philo Farnsworth had been working on his own television system.
In 1927, at the age of 21, Farnsworth completed the prototype of the first working fully electronic TV system, based on this “image dissector.” He soon found himself embroiled in a long legal battle with RCA, which claimed Zworykin’s 1923, patent took priority over Farnsworth’s inventions. The U.S. Patent Office ruled in favor of Farnsworth in 1934 (helped in part by an old high school teacher, who had kept a key drawing by the young inventor), and RCA eventually agreed to pay Farnsworth 💲1 million in licensing fees. However, RCA pursued other litigation and then World War II put a halt on production of most consumer electronics, which delayed RCA paying royalties to Farnsworth. Though viewed by many historians as the true father of television, Farnsworth never earned much from his invention and was dogged by patent appeal lawsuits from RCA. He later moved on to other fields of research and died in debt in 1971.
Although the BBC had begun the world’s first regular TV broadcasts in 1936, Sarnoff used his company's marketing might to introduce the American public to television in a big way at the World’s Fair in New York City in 1939. Under the umbrella of RCA’s broadcasting division, the National Broadcasting Company (NBC), Sarnoff broadcast the fair’s opening ceremonies, including a speech by President Franklin D. Roosevelt.
The Rise of a New Medium
By the 1950s, television had truly entered the mainstream, with more than half of all American homes owning TV sets by 1955.
