Who Invented TV? - History of Television
87There is controversy surrounding the invention of one of the most popular 21st century devices: the television.
The difficulty in deciding who invented the television (TV) centers on the fact that there were several discoveries or inventions all of which together added up to the making of the TV.
Paul Gottlieb Nipkow of Germany developed the "Nipkow disc", a rotating-disc technology which was capable of transmitting pictures via cable, as long ago as 1884. However, it was decades later in the 1920s that the Scots inventor John Logie Baird patented technology for using arrays of transparent rods for transmitting images to be delivered to and viewed on a television set.
Baird's 30-line images replaced back-lit silhouettes with reflections of light. Baird also made it clear that he based his patented technology on the inventions of Nipkow.
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.
But it was electronics inventor Philo Farnsworth who is credited with inventing the first completely electronic television. In 1927 Farnsworth transmitted a television image (a dollar sign) comprising 60 horizontal lines--double the resolution achieved by Baird.
Philo Farnsworth would found Farnsworth Television, Inc. in 1929. In spite of that, Farnsworth insisted to his friends and family that "there's nothing on [the TV] worthwhile", and told his children "I don't want it in your intellectual diet."
However, the pioneering work of Joseph Henry and Michael Faraday with electromagnetism in 1831, the 1862 invention of the pantelegraph (allowing the transmission of still images via cable) by Abbe Giovanna Caselli, and other work by scientists and inventors George Carey, Sheldon Bidwell, Eugen Goldstein, and Bell and Edison, among some others, all led up to Nipkow's 1884 invention.
It was in 1938 that the direct forerunner to the modern analog signal TV was first demonstrated, when German engineer Werner Flechsig patented and unveiled his "shadow mask" color television.
In 1939, television was first demonstrated at the New York World's Fair and the San Francisco Golden Gate International Exposition. At the World's Fair that year, RCA's David Sarnoff showed the world the first televised Presidential speech--given by FDR--while showing off RCA's new line of television receivers.
According to an IEEE Milestone Plaque, it was between 1946 and 1950 that RCA Laboratories invented the world's first "electronic, monochrome compatible, color television system."
But it was in 1938 that the Dumont company began manufacturing TV sets, and soon enough they were the standard against which all other TV sets were measured. DuMont Laboratories had begun researching and developing cathode ray technology in 1931. The Dumont Television Network would become the world's first TV network in 1946. The network was primarily created in order to sell TV sets.
However, anticipating RCA, in 1940 CBS scientists under the aegis of Peter Goldmark created a mechanical color television system based on Baird's later designs. The Federal Communications Commission made the CBS color television technology the American national standard in October of 1950.
In 1946, Goldmark first showed his proprietary color TV system to the FCC. Goldmark's set worked by having a red, blue, and green wheel spin in front of a cathode ray tube.
By 1948, at least one million TV sets had been sold in the U.S., and by 1960 people could buy the Zenith Space Command, the first TV remote control invented by Robert Adler (allegedly to help people avoid having to be subjected to commercials). The ability to tune in UHF stations became federally mandated for TV sets by 1962, and by 1967 the vast majority of U.S. TV broadcasts included a color signal.
Today, the American public is preparing for all TV broadcasts to be made in federally mandated digital signals.
Indeed, the historical development of the TV is a complex series of events, and proclaiming any one man the TV set's inventor seems inaccurate at best.

haha, this is a great hub. It's so great, you've inspired another mini hub (complete with citations and bibliography) in the comments section! good work.
Good Hub. I like it... Any info on the history of digital television? I would like to request a hub on it.
gud topic
who is Guillermo Gonzalez Camarena?
this is some chicken shit!! this aint giving me any fukking info!! man yall need some fukking help!! im tired of this shit!! man all yall are bitches!! fukk yall!!!!!!
still i didnt understood whose d actual inventor
a great hub!i like that
still i dont understand who the inventer is
I cann't understand .. I want to know who invented the TV ..
Thank you.
i still can't find any information
where's the answer boss? who invented tv.........?
For those who still ask "What's the answer to Who invented TV?" there is no one clear inventor, it all depends on how you define Television as there were several inventions created by different people that led up to the TVs we have today. So the inventors of TV could be:
Paul Gottlieb Nipkow
John Logie Baird
Philo Farnsworth
Guillermo Gonzalez Camarena was inventor color TV, but he has a big problem, he was mexican for this razon was deleted from history
This site acturlly dosen't tell u who acturlly invented televison thats all i want to find out...
thanks for d perfect info..was so confused...chris sir...
when there is confusion atleast you can say to whom the credit goes in who invented electricity? please just mention to whom the credit should go.
Some of the comments are too funny! Now check who invinted the TELEPHONE! lol
"still i didnt understood whose d actual inventor"
What is this article was written is a speculation.
Many peaple worked on. But two russians made it.
Zworykin and Sarnoff.
hi people
Hey people heres the answer:
This guy invented the tv:John Logie Baird (August 13, 1888 - June 14, 1946)
this domb
Who invented it, then!!!!!!!!!!!!!!??????????????????????? ARGGGGG
great idea awezome!!!!
damn it!!!!!!!!!!!!!not a single useful info
damn it!!!!!!!!!!!!!not a single useful info
WOW!!!
Thankx for dat info but don't hlp me
The person who first created a televition was Philo Fransworth in San Francisco, California on September 7,1927.
i think the inventors are John Logie Beard and philo farnsworth . but farnsworth only completed the invention , so i think philo farnsworth is the inventor.
ths is realy nt helpin. aftr readin the all article, i stil cant find the required info.
thanks great info
There's no doubt about it - Baird was the man!
Here is the United States Patent, Filed August 14, 1941 by Mexican Inventor Guilermo Gonzalez Camarena
this info really dont tell me anithing about who invented television it is so confused
i never new that its so kwel
the invention is philo farnsworth
nice work but tooooooooooo long
great!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
for me Paul Gottlieb Nipkow of Germany
who made tv i aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
what are you doing with that pictuer
cool
please start with answer
I like this website alto
awesome and interesting to read
WOW YOU INVENTED THE TELEVISION
This really helped, now i may continue with my many workings.
thanks i found out alot of info

RE: "WHO INVENTED TELEVISION".As a working historian and media chronicler for the last 40 years, with an educational background in electrical engineering, I would have to say that "the inventor of television" all depends on definitions.Let's look at the definitions of two words by one of the most authoritative arbiters of the English language, the "Concise Oxford Dictionary":First, the word "invent":"v.t. create by thought, originate... concoct..."However, most people would consider that invention involves more than just the conception of a plan, more than mere speculation on paper. For the thing to be truly INVENTED by a person, it has to be DEMONSTRATED by that person.For example, Charles Cros narrowly beat Thomas Edison to the CONCEPTION of a phonograph; but Edison, in 1877, was the first to DEMONSTRATE it. Therefore Edison is generally considered to be the phonograph's inventor.Radio? Heinrich Hertz proved the existence of "Hertzian" or "radio" waves, but Marconi applied it to a practical signalling system, so Marconi is generally considered to be the inventor of radio.So let's look at the Oxford Dictionary's definition of the word "television":"n. System for reproducing actual or recorded scene at a distance on a screen etc. by radio transmission, usu. with appropriate sounds; vision of distant objects obtained thus: televised programs etc..."In terms of mere conception, there are many claimants to the invention of television systems which were eventually combined with other components to achieve television. Nipkow (1883) invented the scanning disc eventually employed by the earliest television systems. Moore (1917) invented the low-voltage modulated neon lamp used with that disc to receive the earliest television pictures. The alkali metal photocell with its high speed of response, suitable for television, was developed from concepts published by Elster and Geitel (1889). C F Jenkins (1923) transmitted moving pictures scanned from film, but these were usually simple silhouettes and geometric shapes, not three dimensional subjects by reflected light, not direct, no greyscale and certainly not "live".So who was first to assemble a television system and demonstrate it to be capable of transmitting real-time three-dimensional objects, in movement, with a full range of grey scale tones, by reflected light? We MUST give credit to John Logie Baird and his first demonstration of the transmission of a dummy's head - as well as his own head and William Taynton's, in the first week of October 1925. Or, if you prefer the date of Baird's first public display, 26 January 1926, where forty members of Britain's Royal Institution and two journalists attended. Photographs of Baird's 30-line television image were taken in 1926. Although fuzzy and jagged, the image is recognisably that of a human face - and if one had known Baird's business manager, Hutchinson, one would probably have recognised him from that image.The fact that later, electronic (cathode ray tube) systems of television by Campbell-Swinton (in conception only), Zworykin, Farnsworth et al eventually outmoded these earlier TV systems with their mechanical scanners does not detract from Baird's claim to invention. Baird, in October 1925, came first. To apply the same standards, present radio techniques owe little to Marconi's spark-and-coherer methods of the 1890s; modern railways work on an entirely different principle to Stephenson's steam-powered "Rocket" locomotive. But the perception of invention must lie with the earliest techniques that were made to work, and with the pioneers who used those techniques. Farnsworth, for whom so much has been claimed in recent years, was undisputedly the first to get a wholly ELECTRONIC television system to work. This transmitted, according to Abramson's "History Of Television" (1987), only a "blob of light" on 7 September 1927. According to Farnsworth's own notes, his first "real" pictures were not produced by his camera tube until the second week of May, 1928. However Farnsworth's "image dissector" camera tube could not store photoelectric charge for the duration of each picture scan: it was insensitive, and it was not the direct antecedent of the mainstream of electronic television, as Zworykin's "iconoscope" camera and "kinescope" high vacuum receiver CRT were. According to Abramson, Zworykin's camera tube, though receiving an initial patent as early as 1923, was not made to work with film scanning until the end of 1930; it did not produce "live" pictures from a single-sided target plate until 9 November 1931; and a new method for producing a 'mosaic' of photosensitive elements on the camera signal plate provided really practical advances of Zworykin's electronic camera image quality in 1932.Modern CCD cameras and LCD screens have only the vaguest relationship to the cathode ray tubes of Zworykin or Farnsworth. In the case of modern DLP micromirror TV projectors, the display device IS mechanical, with moving "nanomirror" arrays and a rotating colour wheel. Mechanical television also survives in receivers and cameras designed special purposes, or for public displays, such as the DynaScan, refer:http://www.dynascanusa.com/So pardon this historian - an Australian with no particular affiliation to any of these inventors' countries of origin - for sticking his neck out quite categorically and saying, ON THE BASIS OF THESE DEFINITIONS, it's Baird!Regards to all,Christopher Long, amateur radio operator VK3AML, Melbourne, Australia.REFERENCES:Albert Abramson: "The History Of Television, 1880 to 1941", McFarland & Co., Publishers, Jefferson, North Carolina; and London, England, 1987.George and May Shiers: "Early Television, A Bibliographic Guide to 1940", Garland Publishing Inc., New York and London, 1997.Donald F McLean: "Restoring Baird's Image", Institution Of Electrical Engineers, London, 2000.Bruce Norman: "Here's Looking At You, The Story Of British Television 1908 - 1939", BBC and Royal Television Society, London, 1984.R W Burns: "Television: An International History Of The Formative Years", IEE History Of Technology Series, Vol 22, London, 1998.A H Sommer: "Photoemissive Materials", John Wiley and Sons, Inc., New York, 1968.
