Who invented the television?

Answer 1

Television was not invented by a single inventor, instead many people working together and alone, contributed to the evolution of TV.
1831: Joseph Henry's and Michael Faraday's work with electromagnetism makes possible the era of electronic communication to begin.
1862: Abbe Giovanna Caselli invents his "pantelegraph" and becomes the first person to transmit a still image over wires.
1873: Scientists May and Smith experiment with selenium and light, this opens the door for inventors to transform images into electronic signals.
1876: Boston civil servant George Carey was thinking about complete television systems and in 1877 he put forward drawings for what he called a "selenium camera" that would allow people to "see by electricity." Eugen Goldstein coins the term "cathode rays" to describe the light emitted when an electric current was forced through a vacuum tube.
Late 1870's: Scientists and engineers like Paiva, Figuier, and Senlecq were suggesting alternative designs for "telectroscopes."
1880: Inventors like Bell and Edison theorize about telephone devices that transmit image as well as sound. Bell's photophone used light to transmit sound and he wanted to advance his device for image sending. George Carey builds a rudimentary system with light-sensitive cells.
1881: Sheldon Bidwell experiments with telephotography, another photophone.
1884: Paul Nipkow sends images over wires using a rotating metal disk technology calling it the "electric telescope" with 18 lines of resolution.
1900: At the World's Fair in Paris, the 1st International Congress of Electricity was held, where Russian, Constantin Perskyi made the first known use of the word "television."
Soon after, the momentum shifted from ideas and discussions to physical development of TV systems. Two paths were followed:
Mechanical television - based on Nipkow's rotating disks, and
Electronic television - based on the cathode ray tube work done independently in 1907 by English inventor A.A. Campbell-Swinton and Russian scientist Boris Rosing.
1906: Lee de Forest invents the "Audion" vacuum tube that proved essential to electronics. The Audion was the first tube with the ablity to amplify signals. Boris Rosing combines Nipkow's disk and a cathode ray tube and builds the first working mechanical TV system.
1907: Campbell Swinton and Boris Rosing suggest using cathode ray tubes to transmit images - independent of each other, they both develop electronic scanning methods of reproducing images.
American Charles Jenkins and Scotsman John Baird followed the mechanical model while Philo Farnsworth, working independently in San Francisco, and Russian émigré Vladimir Zworkin, working for Westinghouse and later RCA, advanced the electronic model.
1923: Vladimir Zworykin patents his iconscope a TV camera tube based on Campbell Swinton's ideas. The iconscope, which he called an "electric eye" becomes the cornerstone for further television development. He later develops the kinescope for picture display.
1924 - 1925: American Charles Jenkins and John Baird from Scotland, each demonstrate the mechanical transmissions of images over wire circuits. Photo Left: Jenkin's Radiovisor Model 100 circa 1931, sold as a kit. Baird becomes the first person to transmit moving silhouette images using a mechanical system based on Nipkow's disk. Vladimir Zworykin patents a color television system.
1926: John Baird operates a 30 lines of resolution system at 5 frames per second.
1927: Bell Telephone and the U.S. Department of Commerce conduct the first long distance use of TV, 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.” Philo Farnsworth files for a patent on the first complete electronic television system, which he called the Image Dissector.
1928: The Federal Radio Commission issues the first television license (W3XK) to Charles Jenkins.
1929: Vladimir Zworykin demonstrates the first practical electronic system for both the transmission and reception of images using his new kinescope tube. John Baird opens the first TV studio, however, the image quality was poor.
1930: Charles Jenkins broadcasts the first TV commercial. The BBC begins regular TV transmissions.
1933: Iowa State University (W9XK) starts broadcasting twice weekly television programs in cooperation with radio station WSUI.
1936: About 200 hundred television sets are in use world-wide. The introduction of coaxial cable, which is a pure copper or copper-coated wire surrounded by insulation and an aluminum covering. These cables were and are used to transmit television, telephone and data signals. The 1st "experimental" coaxial cable lines were laid by AT&T between New York and Philadelphia in 1936. The first “regular” installation connected Minneapolis and Stevens Point, WI in 1941. The original L1 coaxial-cable system could carry 480 telephone conversations or one television program. By the 1970's, L5 systems could carry 132,000 calls or more than 200 television programs.
1937: CBS begins TV development. The BBC begins high definition broadcasts in London. Brothers and Stanford researchers Russell and Sigurd Varian introduced the Klystron in. A Klystron is a high-frequency amplifier for generating microwaves. It is considered the technology that makes UHF-TV possible because it gives the ability to generate the high power required in this spectrum.
1939: Vladimir Zworykin and RCA conduct experimentally broadcasts from the Empire State Building. Television was demonstrated at the New York World's Fair and the San Francisco Golden Gate International Exposition. RCA's David Sarnoff used his company's exhibit at the 1939 World's Fair as a showcase for the 1st Presidential speech (Roosevelt) on television and to introduce RCA's new line of television receivers – some of which had to be coupled with a radio if you wanted to hear sound. The Dumont company starts making tv sets.
1940: Peter Goldmark invents a 343 lines of resolution color television.
1941: The FCC releases the NTSC standard for black and white TV.
1943: Vladimir Zworykin developed a better camera tube - the Orthicon. The Orthicon (Photo Left) had enough light sensitivity to record outdoor events at night.
1946: 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. This mechanical means of producing a color picture was used in 1949 to broadcast medical procedures from Pennsylvania and Atlantic City hospitals. In Atlantic City, viewers could come to the convention center to see broadcasts of operations. Reports from the time noted that the realism of seeing surgery in color caused more than a few viewers to faint. Although Goldmark's mechanical system was eventually replaced by an electronic system he is recognized as the first to introduce a broadcasting color television system.
1948: Cable television is introduced in Pennsylvania as a means of bringing television to rural areas. A patent was granted to Louis W. Parker for a low-cost television receiver. One million homes in the United States have television sets.
1950: The FCC approves the first color television standard which is replaced by a second in 1953. Vladimir Zworykin developed a better camera tube - the Vidicon.
1956: Ampex introduces the first practical videotape system of broadcast quality.
1956: Robert Adler invents the first practical remote control called the Zenith Space Commander, proceeded by wired remotes and units that failed in sunlight.
1960: The first split screen broadcast occurs on the Kennedy - Nixon debates.
1962: The All Channel Receiver Act requires that UHF tuners (channels 14 to 83) be included in all sets.
1962: AT&T launches Telstar, the first satellite to carry TV broadcasts - broadcasts are now internationally relayed.
1967: Most TV broadcasts are in color.
1969: July 20, first TV transmission from the moon and 600 million people watch.
1972: Half the TVs in homes are color sets.
1973: Giant screen projection TV is first marketed.
1976: Sony introduces betamax, the first home video cassette recorder.
1978: PBS becomes the first station to switch to all satellite delivery of programs.
1981: NHK demonstrates HDTV with 1,125 lines of resolution.
1982: Dolby surround sound for home sets is introduced.
1983: Direct Broadcast Satellite begins service in Indianapolis, In.
1984: Stereo TV broadcasts approved.
1986: Super VHS introduced.
1993: Closed captioning required on all sets.
1996: The FCC approves ATSC's HDTV standard. Billion TV sets world-wide.

Answer 2

So... who really invented television?

As compelling as the story of Philo T. Farnsworth may be, the historical record with regard to "who invented television" remains fuzzy at best, deliberately distorted at worst. The debate often comes down to a simple question: Does any single individual deserve to be remembered as the sole inventor of television? Can we create for television the kind of mythology of individual, creative genius that history has bestowed on Morse, Edison, Bell, or the Wright Brothers?
Before that date, television was the province of Newtonian electro-mechanical engineers who employed spinning disks and mirrors in their crude attempts to scan, transmit, and reassemble a moving image. The inventions of Jenkins, Ives, Alexanderson, Baird, and others are all similar in their reliance on the spiral-perforated, spinning disk first proposed in the 1880s by the German Paul Nipkow. These contraptions were engineering marvels in their own quaint way, but they were not the sort of breakthrough that Farnsworth introduced, nor is anything left of their technology in the system of television that is in use around the world today.

Answer 3

While electromechanical techniques were developed prior to World War II, most notably by Charles Francis Jenkins and John Logie Baird, completely electronic television systems relied on the inventions of Philo Taylor Farnsworth, Vladimir Zworykin and others to produce a system suitable for mass distribution of television programming. Commercial broadcast programming, following years of experimental broadcasts seen only in a few specially-equipped homes, occurred in both the United States and the United Kingdom before World War II.

Answer 4

Mechanical Television History
Paul Gottlieb Nipkow
John Logie Baird
Charles Francis Jenkins
Karl Braun - Cathode Ray Tube
Electronic Television History
Vladimir Kosma Zworykin
Philo T. Farnsworth

What John Logie Baird did towards the development and promotion of mechanical television in Britain, Charles Francis Jenkins did for North America. Jenkins invented a mechanical television system called radiovision and claimed to have transmitted the earliest moving silhouette images on June 14, 1923.

The History of the Cathode Ray Tube
Electronic television is based on the development of the cathode ray tube, which is the picture tube found in modern TV sets. German scientist, Karl Braun invented the cathode ray tube oscilloscope (CRT) in 1897.

Vladimir Kosma Zworykin invented the cathode-ray tube called the kinescope in 1929, a tube needed for TV transmission. Vladimir Kosma Zworykin also invented the iconoscope, an early television camera. See the personal photographs of television pioneer Dr. Vladimir Kosma Zworykin and his involvement with television history
