Title: So
1So.who invented it?? The controversy.
- No other invention in history has been so hotly
disputed as the prestigious claim to the
invention of 'Tele-vision or 'long-distance
sight' by wireless. - Since Marconis invention of wireless telegraphy
in 1897, the imagination of many inventors have
been sparked with the notion of sending images as
well as sound, wirelessly. The first documented
notion of sending components of pictures over a
series of multiple circuits is credited to George
Carey. Another inventor, W. E. Sawyer, suggested
the possibility of sending an image over a single
wire by rapidly scanning parts of the picture in
succession.
2So.who invented it??
- On December 2, 1922, in Sorbonne, France, Edwin
Belin, an Englishman, who held the patent for the
transmission of photographs by wire as well as
fiber optics and radar, demonstrated a mechanical
scanning device that was an early precursor to
modern television. Belins machine took flashes
of light and directed them at a selenium element
connected to an electronic device that produced
sound waves. These sound waves could be received
in another location and remodulated into flashes
of light on a mirror. - The credit as to who was the inventor of modern
television really comes down to two different
people in two different places both working on
the same problem at about the same time - Vladimir Kosma Zworykin, a Russian-born American
inventor working for Westinghouse, and - Philo Taylor Farnsworth, a privately backed farm
boy from the state of Utah. Zworykin is
usually credited as being the father of modern
television. - the patent for the heart of the TV, the electron
scanning tube, was first applied for by Zworykin
in 1923, under the name of an iconoscope. The
iconoscope was an electronic image scanner -
essentially a primitive television camera. - Farnsworth was the first of the two inventors to
successfully demonstrate the transmission of
television signals, which he did on September 7,
1927, using a scanning tube of his own design.
Farnsworth received a patent for his electron
scanning tube in 1930.
3So.who invented it??
- Another player of the times was John Logie Baird,
a Scottish engineer and entrepreneur who
'achieved his first transmissions of simple face
shapes in 1924 using mechanical television. On
March 25, 1925, Baird held his first public
demonstration of 'television' at the London
department store Selfridges on Oxford Street in
London. In this demonstration, he had not yet
obtained adequate half-tones in the moving
pictures, and only silhouettes were visible.' -
MZTV - In the late thirties, when RCA and Zworykin, who
was now working for RCA, tried to claim rights to
the essence of television, it became evident that
Farnsworth held the priority patent in the
technology. The president of RCA sought to
control television the same way that they
controlled radio and vowed that, - RCA earns royalties, it does not pay them, and
a 50 million dollar legal battle subsequently
ensued. - In the height of the legal battle for patent
priority, Farnsworths high school science
teacher was subpoenaed and traveled to Washington
to testify that as a 14 year old, Farnsworth had
shared his ideas of his television scanning tube
with his teacher.
4And the winner is.
- Patent priority status ruled in favor of
Farnsworth. - RCA, for the first time in its history, began
paying royalties for television in 1939. Philo
Farnsworth was recently named one of TIME
Magazine's 100 Greatest Scientists and Thinkers
of the 20th Century.
51928Television started in the 1920s as a
peepshow device. This means, the images could
only be seen by one viewer gazing into a narrow
opening. The quality of these early,, television
sets, with tiny vertical screens, was very poor.
However, the images where there and received in a
large part of Europe via the 'short wave', also
used for radio.
61934Many early television sets where housed in
huge Art-Deco cabinets, often wonderful examples
of furniture design. Even these large, pre 1936,
cabinets only displayed a tiny 30 lines
television screen
7The first commercial television sets came on the
market in 1930 by the Baird Television
Development Company LTD. These sets however
where expensive and housed in a cast iron cabinet
of beautiful design

9 Television During World War-II
- World War-II halted nearly all television
broadcasting worldwide - All commercial production of television equipment
is banned for the remainder of the war. -
- NBC's commercial TV schedule is canceled.
- Television is allowed to continue broadcasting on
a very limited basis at some stations. In
England, however, ALL broadcasting comes to a
complete halt, until June 7, 1946. -
101946
- The United States returns to peace time
production. - RCA begins production of 630-TS, the first
television designed and manufactured after the
war. Approximately 10,000 units sold by the end
of the year, with about 43,000 sold of this model
before production ends in 1949. Other
manufacturers used the RCA chassis, and placed it
in a cabinet of their own design. The initial
RCA selling price was 352.

- One of television's critics, Darryl F. Zanuck,
head of 20th Century Fox (movies) was quoted
saying "Television won't be able to hold on to
any market it captures after the first six
months. People will soon get tired of staring at
a plywood box every night."
