[edit] Farnsworth's World's *First* Public (All-Electronic) Demonstration?

This article currently states: "Farnsworth gave the world's first public demonstration of a complete all-electronic television system on 25 August 1934 at the Franklin Institute in Philadelphia." I am confused. Can anybody enlighten me on how this 1934 demonstration compares to the 1931 German Funkausstellung in Berlin demonstration by Manfred von Ardenne? It would be very helpful if somebody could comment on the "all-electronic" status of the Berlin demonstration. —Preceding unsigned comment added by Cyberroach (talk • contribs) 22:01, 23 February 2008 (UTC)

The key word in the sentence you quoted above is "complete". The all-electronic system that Manfred von Ardenne demonstrated in 1931 did not have a camera tube; it used a cathode ray tube as a flying spot scanner to scan motion picture films and slides. A fuller explanation comes in the same paragraph of the article:
But Farnsworth was the first to coordinate both electronically scanned television cameras and electronically scanned television receivers, and present live, moving, half-tone (grayscale) images with them.
Von Ardenne's accomplishment is mentioned in a footnote to that paragraph. For more information, see Zworykin, Pioneer of Television by Albert Abramson, p. 111. — Walloon (talk) 15:43, 5 June 2008 (UTC)

[edit] Modern TV?

This article covers from the early days of television to the 60s and 70s. Why is modern television history not included? Items such as ATSC (over-the-air ditigal broadcasts), HDTV and satellite television are all parts of television history that are not included. Any particular reason? EvilReborn 03:59, 24 November 2006 (UTC)

I wrote much of the material from the 1920s to the 1950s, and I plead guilty. I have not read up on television developments past that period. Hopefully someone who has, can put some balance into this article. — Walloon 06:46, 24 November 2006 (UTC)

[edit] Willard Geer

Removing paragraph:

Of note, though RCA is largely credited with developing the first commercial color television in the United States, the invention was actually first patented by University of Southern California (USC) physics professor Willard Geer in 1944. One month after he patented this invention RCA also filed for a patent, then sued Mr. Geer. Willard Geer eventually won the suit and was paid $15,000 by RCA.

But RCA is not "largely credited with developing the first commercial color television" in the U.S. Color television had been demonstrated as far back as 1928 by John Logie Baird. The first commercial color television system was by CBS, approved by the FCC in 1950, on the air in 1951, with the first CBS brand sets manufactured in 1951. The NTSC system, with hardware developed by RCA, was not approved until 1953, and the first RCA brand sets were manufactured in 1954, several months after Westinghouse had color sets on the market. — Walloon 00:09, 19 May 2006 (UTC)

[edit] González Camarena

Guillermo González Camarena filed his first color television patent in Mexico, for a field sequential color adaptor, on August 19, 1940. Peter Goldmark, chief engineer for CBS television development, first demonstrated his field sequential color system at the CBS Laboratory in June 1940 to CBS management on a 3-inch screen enhanced with a magnifier placed in front of the screen. CBS first broadcast its field sequential color system as early as August 28, 1940, and demonstrated it for a delegation of FCC Commissioners and engineers on September 4, 1940. Article by Robert B. Cooper.

And let's not forget that John Logie Baird had already displayed color television in 1928, and Bell Labs had demonstrated it in 1929. Baird gave another demonstration of color television, this time using a cathode ray tube and a revolving disk of colored filters, in 1939 — essentially what González Camarena offered in his 1940 patent.

Also, the patent (note spelling, not "pattent") number 2,296,022 listed for González Camarena's 1940 invention in an earlier version of this article is actually for a "monogram attachment" by inventor M. Chernow, filed in 1939. The correct patent number for González Camarena is 2,296,019.

González Camarena is written about in the "Mexico" subsection of the History of Color Television section. — Walloon 09:18, 8 June 2006 (UTC)

[edit] Broadcast television: relay

The sentence "At first, terrestrial broadcasting was the only way television could be distributed. Because bandwidth was limited, government regulation was normal." is unclear. High frequency radio relays were used (something like microwave?) very early for remotes and for feeding broadcasts to nearby cities. The article implies that, say, Philadelphia would pick up a New York broadcast from their regular broadcast frequency and repeat it to their viewers, which I do not believe to be the case. The second sentence does not seem to follow from the first.

The book "The Future of Television" by Orrin E. Dunlap, New York: Harper, 1942 says (p8) that coax was installed between New York and Philadelphia by that date for TV relays, and that high frequency radio relays were in the works. NBC had used such a radio link to send pictures from Camp Upton.L.I. to NYC 68 miles with 2 repeaters. Edison 14:18, 12 July 2006 (UTC)

[edit] First sports broadcast

I have removed the following paragraph:

The first-ever sports broadcast on television took place on May 17, 1939 at the second game of a double-header between the Columbia University Columbia Lions and the Princeton University Tigers football teams at Columbia's Baker Field in upper Manhattan. NBC wanted to experiment with using television to broadcast live sporting events. The test was so successful that they soon began broadcasting major league sports.

England's BBC had been broadcasting sports events for several years before this, and Germany televised the 1936 Summer Olympics. — Walloon 01:06, 22 November 2006 (UTC)

The two men who told me this are now dead, so I have no reference. According to the late Ellery Tuller, K8CVO, early video broadcasts of major league baseball games were first married to AM play-by-play by amateur radio operators. Of course us hams like to take credit for any development in technology.--W8IMP 06:45, 14 April 2007 (UTC)

[edit] Telephane

What about the Telephane invented by the Australian Henry Sutton in 1885 [1]. Ozdaren 15:16, 18 June 2007 (UTC)

Sutton's invention was published but never demonstrated. On the transmission side it was really no different from Nipkow's proposal. On the receiver side, its innovation was to use a Kerr cell (a small glass cell holding a drop of carbon bisulphide) as the optical medium stimulated by electrodes. Baird in the 1920s and others experimented with Kerr cells, but the illumination was always insufficient. — Walloon (talk) 16:29, 5 June 2008 (UTC)

[edit] Telephotograph

Could information from this article from the 1907-02-24 edition of The New York Times be incorporated? It seems to contain one of the first mentions of the concept of 'television':

The new 'telephotograph' invention of Dr. Arthur Korn, Professor of Physics in Munich University, is a distinct step nearer the realization of all this, and he assures us that 'television,' or seeing by telegraph, is merely a question of a year or two with certain improvements in apparatus.

Thanks. --the Wild Falcon (talk | log) 13:48, 20 September 2007 (UTC)

Actually, the concept of television, if not by name, had been written about since the 1880s. Per your suggestion, I have linked the New York Times article on Dr. Korn to the existing text about photo telegraphy in 1907 (which was referring to his demonstration). — Walloon 16:57, 20 September 2007 (UTC)

[edit] First TV Series

What was the first TV series? —Preceding unsigned comment added by 71.32.244.191 (talk) 10:26, 19 December 2007 (UTC)

[edit] Kenjiro Takayanagi

The first to create a working prototype of the cathode ray tube based, fully electronic television receiver was Kenjiro Takayanagi, a Japanese inventor, who successfully demonstrated the device at Hamamatsu Industrial High School on Christmas, 1926. This was the world's first example of the all-electronic model of the television; the basic architecture still used in present day (pre LCD) television.

I have removed the paragraph above from the article because it is incorrect. According to the Web site The Evolution of TV: A Brief History of TV Technology in Japan,

Takayanagi constructed a system that utilized a mechanical Nipkow disk and a photoelectric tube in the transmitting device, and an electric Braun tube in the receiving device. He succeeded in displaying a clear image of the character “[Japanese character]” on a Braun tube on December 25, 1926 (on a mechanical and electrical system with 40 scanning lines).

In order words, he demonstrated in 1926 what Boris Rosing and his student Vladimir Zworykin had achieved in Russia in 1911, also using a Braun tube. See the section in this Wikipedia article on mechanical television. — Walloon (talk) 15:36, 24 January 2008 (UTC)

[edit] Hovhannes Adamyan

I have removed the following three paragraphs from the section on electronic color television:

In 1905 in the laboratory of Berlin Univerisity Professor Arthur Korn, a student of the same University Hovhannes Adamyan made his first invention, when he improved the device constructed by his teacher and gave a transmittable picture. In 1908 the Kaiser's License Office of Berlin issued a license to Adamyan "For creating a device for transmission of a picture or several pictures through electricity". For the first time in history of television development Adamyan substantiated the idea of transmitting a black-and-white picture to the scientific world.[citation needed] The license was followed by testing of the two-color TV in Berlin, the first experience ever in transmitting of the color picture.[citation needed]
Adamyan has been acknowledged as the inventor of the color television.[citation needed] The scientist received French and Russian licenses for his invention in 1908. In 1921, during the all-Russian Electro technical Conference in Moscow, he presented the results of his studies for transmitting a picture on long distances. In a letter addressed to his sister, Adamyan wrote: "Although I am invited to Germany, I wish to make my first large scientific experiment in my Motherland". In 1925 Adamyan presented the first scheme of the color television sequential system at the Yerevan State University, the tri-color television, which was named "Herates" (the far-sighted). Adamyan's invention was applied three years later in London. In 1930-ies Adamyan was also acknowledged as the inventor of the prototype of the modern video player.[citation needed]
In 1945-1951 US Columbia (CBS) Radio company tested Adamyan's invention and only in 1953 it was accepted, and later replaced by NTSC system.[citation needed]

Adamyan's name does not appear in Television: An International History edited by Anthony Smith, Television: An International History of the Formative Years by R.W. Burns, or The History of Television, 1880 to 1941 by Albert Abramson. His name appears on the Web only on Armenian-oriented sites. — Walloon (talk) 05:52, 5 June 2008 (UTC)
