The invention of television emerged from the work of many individuals in the late 19th and early 20th centuries. Electronic television was first successfully demonstrated by Philo Taylor Farnsworth in San Francisco in 1927. Television transmits sound and moving images through a telecommunication system, and has evolved from early monochrome transmission to modern color and 3D transmission.

2. The invention of the television was the work of many
individuals in the late 19th century and early 20th
century. Electronic Television was firstly successfully
demonstrated in San Francisco on September 7,1927.
The system was designed by Philo Taylor Farnsworth.

4. The word television come from Ancient Greek { tele }
meaning “far”, and Latin { visio } meaning “sight”.

5. Television commonly referred to as TV, telly or the tube,
is a telecommunication medium used for transmitting
sound with moving images in monochrome (black and
white), or in color, and two or three dimensions.

6. In 1911, Boris Rosing and his students Vladimir
Zworykin created a system that used a mechanical
mirror drum scanner to transmit, in Zworykin’s words,
“very crude image” over wires to the “Braun tube”.
Moving images were not possible in the scanner.

7. Among the earliest published proposals for television
was one by Maurice Le Blanc in 1880 for color system ,
include the first mentions in television literature of
line and frame scanning, although he gave no practical
details.
Polish inventor color television Jan Szczepanik
patented a color television system in 1897, using a
selenium photoelectric cell at the transmitter and a
electromagnet controlling an oscillating mirror and a
moving prism at the receiver.

8. By the 1920s, when amplification made television
practical, Scottish inventor John Loge Baird employed
the Nipkow disk in his prototype video system.
On march 25, 1925, Baird gave the first public
demonstration of televised silhouette images in
motion, at Selfridge’s Department Store in London.

9. In 1928, Baird company(Baird television Development
Company/Cinema television) broadcast the first
transatlantic television signal, between London and
New York, and first shore to ship transmission.

10. Herbert E. Ives and Frank Gray of bell telephone
laboratories gave a dramatic demonstration of
mechanical television on 7 April 1927.
Their reflected light television system include both
small and larger viewing screens. The small receiver
had 2- inch's wide by 2.2- inch's high screen.

11. Scottish inventor John Logie Baird demonstrated the
worlds first color transmission on July 3, 1928, using
scanning discs at the transmitting and receiving ends
with filters of apertures, each spiral with filters of a
different primary color; and three light sources at the
receiving end, with a commutator to alternate their
illumination .
