Did you ever wonder what communication was
before telephones?
My grandfather once told me,
what communication was in his
time.
Communication now is used with
cellular phones, but in his time,
what do you think they used?
Life before the Telephone
Communication before the telephone was
consisted of messages carried by the
postal office
Meaning, lives before were very harsh
cause they need to go to the post office just
to send a note, or a letter to people they
want to message to, unlike now, we can
send messages in mere seconds
History of the telephone
Im about to show you guys
the history of the telephone
Year 1900-1905
First mass-marketed camera, 'The Kodak Brownie' The
Wireless Telegraph Trading Signal Co. Ltd changes its
name to the 'Marconi Telegraph Co.' Marconi gets his
English patent for his tuning equipment.
The Car radio is invented by Guglielmo Marconi, an Italian
engineer working in London. It was used for wireless
telegraphy experiments
Marconi builds a radio station in Glace bay, it is during the
trip that he discovers the harmful influence of solar
radiation tramissions, it creates a magnetic detector
Working from Edison’s discovery, his discovery the radio
wave detector opens the door to advanced radio
commmunication, he builds “the Rotating Oscilator” and
discovers the directive properties of the antenna
The “aerial” antenna is first tested to the radio station in
Glace bay, this could help on radio communication at
world war 1
1906-1911
 Lee De Forest invented “AUDION” something that can
detect and generate, detect and amplify radio waves, it
revolutionizes radio communications providing the first
technology for loud and clear radio transmission of the
human voice, the first radio broadcast was created
 The De Forest 4th Avenue Radio Telephone Company
in New York begins a program of regular radio
broadcasts, consisting entirely of gramophone music At
a rate of fifteen cents per word, the public can send
messages across the Atlantic. This is made possible by
the first transatlantic radio-telegraph stations, based in
Glace Bay, Canada and Clifden, Ireland.
 The Calvary Brigade of the British Army forms a
wireless company to handle communication on the
field. Direct telephone links to New York, Denver
Colorado are established
1912-1921
 The heterodyne radio receiver is invented, it generates its
own signal.
 British scientist John Gott invents a system that uses
current reversals for telegraph transmissions
 Guglielmo Marconi experiments successfully using the
triode thermionic valve, the birth of radiophony.
 Ray Kellog invents the electronic speaker, the wireless
telegraph begins between Japan and US
 The development of aerial communication is given a
boost when Major C.E. Prince demonstrates his wireless
telephone
 An indispensable aid to long-distance wireless
communication is created
 KDKA , a small radio station in Pittsburgh begins
broadcasting on November 2. The world's first commercial
radio station,
 Even sports got transmitted all over the stations,
especially the US
1922-1924
 Alexander Graham Bell Dies at Nova Scotia, on his
funeral, all US and Canadian telephone is temporary
disconnected to honor the man who revolutionized
human communication
 Western Electric Corporation patents electrical sound
recordin, Chester W. Rice and Edward W. Kelllog of
General Electric patent a dynamic loudspeaker
 A short wave "beam" system transmits the first direct
wireless link-up from Cornwall, England, to Cape
Town, South Africa. "We speak across space and
some day we shall see as we speak," is the famous
message predicting the advent of television
 Large towns in Britain may now tune into one of the
eleven new radio transmitters that have been
installed to supplement the broadcasting range of the
main stations. 70% of the British public is now within
range of good, clear radio transmission
1925-1930
 The BBC (British Broadcasting Corporation), CBC (Columbia

Phonographic Broadcasting System) later CBS, (Columbia
Broadcasting System) are founded.Commercial transatlantic
telephone service becomes available January 7, 1927. The
first phone call takes place between the editor of the London
Daily Mail on Fleet Street and his New York correspondent.
The United Independent Broadcasters (UIB), a 16-station
radio network, is formed by promoter George Coats and
former RCA executive Maj. Andrew J.
American inventor E. F. W. Alexanderson demonstrates the
first home television receiver in Schenectady, New York. It
consisted of a 3 inch screen and delivered a poor and
unsteady picture.
In London, John Logie Baird opens the world's first television
studio, but is still able to produce only crude and jerky
images. However, because Baird's television pictures carry
so little visual information, it is possible to broadcast them
from ordinary medium-wave radio transmitters.
The car radio is introduced in the US
NBC is granted an experimental broadcast licence.
1930-1950
Television was introduced to the
Russians
There are 2,000 televisions used in the
world
CBS begins television broadcast
The first cable television system
appears in the US
In USA, community antenna television
is introduced, forerunner to cable
1951-1970
The first colour television transmissions using
the Peter Goldmark colour system begin in
the U.S.
In the US, Armour Research demonstrates a
crude VTR - Video Tape Recorder - to
Alexander Poniatov and Ampex executives
Television sets in American homes pass the
22 million mark
There are 951 VTRs in use worldwide
The US is estimated to have 78 million of the
world's 200 million TV sets, the USSR 25
million, Japan 20.5 million, the UK 19 million,
W. Germany 13.5 million and France 10
