1925
- John Logic Baird, Scottish inventor earned his
place in history when he first demonstrates his
mechanical television system at London Department
store Selfridges & Co.
Though his system
of mecanical spinning discs amounted to little more
than moving silhouettes, it was a start. By the
early 30s radio enthusiasts could buy kits to build
Baird's "Televisor" receivers to pick up perodic
Baird Studio/BBC telecasts. Those programs usually
consited of a 30 line picture with sound. Part01 •

1920
- A New Industry
Evolves
- Following the
patenting of the telephone in 1876 and the
subsequent expansion of telephony, the
International Telegraph Union began, in 1885, to
draw up international legislation governing
telephony. With the invention in 1896 of wireless
telegraphy -- the first type of
radiocommunication -- and the utilization of
this new technique for maritime and other
purposes,
•
1920 - But of all the stations on the air in the
early 1920s, the one to stir the attention of the
public and the industry alike was AT&T's WEAF
in New York.
•
1920 - it was decided to convene a preliminary
radio conference in 1903 to study the question of
international regulations for radiotelegraph
communications. The first International
Radiotelegraph Conference held in 1906 in Berlin
signed the first International Radiotelegraph
Convention, and the annex to this Convention
contained the first regulations governing wireless
telegraphy. These regulations, which have since
been expanded and revised by numerous radio
conferences, are now known as the Radio
Regulations.

1920 - The year 1920 saw the beginning of sound
broadcasting at the improvised studios of the
Marconi Company, and in 1927, the International
Radio Consultative Committee (CCIR) was established
at a conference held in Washington D.C. The
International Telephone Consultative Committee
(CCIF, set up in 1924), the International Telegraph
Consultative Committee (CCIT, set up in 1925), and
the CCIR were made responsible for coordinating the
technical studies, tests and measurements being
carried out in the various fields of
telecommunications, as well as for drawing up
international standards.

station in a little shack atop its nine story
factory in Pittsburgh, KDKA. November 2, 1920,
Frank Conrad and Donald Little broadcast election

that is credited with starting a rush to build
stations, and purchase receivers. ( 91 K Wav) not
the actual broadcast, but an interesting

By late in the year, radio is being acclaimed as
the newest form of entertainment for the home. The
first superheterodyne circuit is announced by
Armstrong. Westinghouse purchases the Superhet
patent from Armstrong, along with several patents
from Reginald Fessenden and Michael Pupin. The 'C'
battery is introduced to provide bias voltage. This
helps the 'B' battery last longer by reducing the
amount of plate current needed on tubes. Radio
experimenters spent over 2 Million dollars for
radio parts in 1920.

New radios - superhets, reflex sets, TRF's, and

wealthy suburban and larger metropolitan areas.

Tesla a hopeless businessman, but also he was
pretty careless with money. John O'Neil summed up
his problem, saying that he lacked the personality
(and character) that made possible the securing of
financial returns directly from his inventions.
Throughout most of his life, he lived in hotels,

Act of
1927
•
1927
- RADIO ACT OF 1927 - The situation became chaotic
with many stations choosing their own frequencies,
and operating almost independently of any
government regulation, until congress enacted the
Radio Act of
1927;
This legislative
act remains the cornerstone of American television
policy six decades after its initial passage.
Though often updated through amendments, and itself
based on the pioneering Radio Act of 1927, the 1934
legislation which created the Federal
Communications Commission has endured remarkably
well through an era of dramatic technical and
social change; Congress first specifically
regulated broadcasting with its 1927 Radio Act
which created a Federal Radio Commission designed
to regulate in "the public interest, convenience,
or necessity." But federal regulation of
communications was shared by the Department of
Commerce and the Interstate Commerce Commission. By
1934 pressure to consolidate all telecommunication
regulation for both wired and wireless services
prompted new legislation with a broader
purpose.
•
1927 - Televisions are being sold in kit form. The
FRC, Federal Radio Commission begins to regulate
broadcasting. Their first act was to revoke all
licenses, and then assign frequencies and power
levels.
•
1927 - The 1927 International Radiotelegraph
Conference also allocated frequency bands to the
various radio services in existence at the time
(fixed, maritime and aeronautical mobile,
broadcasting, amateur and experimental), to ensure
greater efficiency of operation in view of the
increase in the number of radiocommunication
services and the technical peculiarities of each
service.

equipment for converting an optical image into an

tubes, electrical scanners, electron multipliers,
and photoelectric materials. He also contributed to
the development of radar systems, vacuum tubes, and
the generation of electrical energy by atomic
fusion.

the image on the screen were almost a quarter-inch

•
1927f - Since the networks won't likely re-enact
Farnsworth's big moment, you'll have to visualize
it for yourself. The setting: his modest San
Francisco lab where, on Sept. 7, 1927, the
21-year-old self-taught genius transmitted the
image of a horizontal line to a receiver in the
next room ••• Later that day, he
triumphantly wired one of his backers in Los
Angeles: "THE DAMNED THING
WORKS!"••• It worked -- just like
Farnsworth had imagined when, as a 14-year-old
Idaho farmboy already obsessed with inventing
television, he had been plowing a field and
realized an image could be scanned onto a picture
tube the same way: row by row.

modern luxury as early as 1908. In the original
