Mechanical and Mechanical and
ElectronicElectronic
In the early days of
television there were
two experimental
paths: Mechanical and
Electronic.
Inventors were either
experimenting with
mechanical disks or
cathode ray tubes.

Mechanical ScanningMechanical Scanning
The beginnings of mechanical television can be traced to the invention
of a scanning disk patented by Paul Gottlieb Nipkow in 1884

The device consisted of a disc with a spiral of holes.
As the disc spins, the eye of the viewer blurs the
points together to re-create a full picture.

Although it’s not known if he ever built the device,
the idea became the basis for many early television
systems.

Both Charles Jenkins and John Logie Baird

Charles Francis Jenkins claimed to have transmitted the earliest moving
images in 1923 using what he called Radiovision. In 1925 he publicly
demonstrated synchronized transmission of pictures and sound.

John Logie Baird, Scottish inventor, first transmissions of simple face
shapes in 1924 using mechanical television. March 25, 1925, Baird
demonstrated "television" at London department store Selfridges.
Only silhouettes were visible.

From 1929 to 1935, the BBC used Baird’s
system until it was replaced by electronic
systems.
Although mechanical scanning was not the
winning system, Baird continued to make
developments in the field demonstrating
colour television in 1939 using a cathode ray
tube.

Television was first
successfully demonstrated
in San Francisco in 1927 by
Philo Farnsworth, a 21-
year-old inventor using
Allen Dumont's cathode
ray tube
Philo T FarnsworthPhilo T Farnsworth
As a young boy, living on a farm, Philo
came up with the idea of electronically
scanning images for transmission. He
shared the idea with his high school
teacher at Rigby High.

Rigby High School, Rigby, Idaho
Farnsworth moved to California to work
on an electronic television system and in
1927 his "Image Dissector" transmitted
the first electronic television image to a
screen.
He spent years arguing over patent rights
with David Sarnoff and engineer Vladimir
Zworykin of RCA but In 1934 the U.S.
Patent Office sided with him. In 1939
Farnsworth sold his patents to RCA.

Long Distance TV Transmission
Transmission of image and audio of Herbert Hoover, Secretary of Commerce
Audio: “Today we have, in a sense, the
transmission of sight for the first time in the
world’s history,” Hoover said. “Human genius
has now destroyed the impediment of distance
in a new respect, and in a manner hitherto
unknown.”

long distance TV with an

Washington to New York

Historical Perspective: 1940s
After the FCC Regulation’s in 1941, the
television stations broadcast for only a few
hours in the evening
Basically they recreated radio shows, news,
and sports.
6 months after commercial broadcasting
began, the US entered World War II and
production of television equipment stopped
and most TV stations were shut down.
Only a few experimental stations stayed on
the air during the war with only a few hours of
broadcasting.
In 1946 after the war the three networks-CBS,
NBC, ABC began serious broadcasting.

The I Love Lucy Show mirrored the stereotypical view of women in the 50s.
In the show Ricky was the breadwinner, and Lucy the housewife.
In real life Lucille Ball was a full partner in the writing and production.

Twenty One and Game Show Scandals
The trouble was that the game show had made the handsome Van Doren a
winner. In 1958 disgruntled former contestants reported that the games were
rigged and contestants coached. Winners had been supplied answers in advance
and the high-drama match-ups were choreographed.
Congressional hearings followed but there had been no laws; laws were created
to prohibit fixing games. Networks and sponsors acknowledged the public's
distaste and kept game shows off the air for a period of time. The quiz show
scandals made the networks forever leery of "single sponsorship."
