Interested in reading
about some old technology?
I recently
read a book that should
interest anyone who
works in broadcasting
in the United States.
The book, “Inventing
American Broadcasting
1899–1922,” is by Susan
J. Douglas, a professor in the Department
of Communications at the University
of Michigan. It is part of the series “Johns
Hopkins Studies in the History of Technology,”
so it has a pretty good pedigree.
When I came across mention of this book
several months ago, I was surprised that
I had not heard of it before, particularly in
that it was first published in 1987. Oh well,
I guess I was busy in 1987—in fact I know
I was.
This book is a great source for the reader
who wants an accurate, unbiased account
of just where American broadcasting came
from, as well as being “A superb portrait of
the communications revolution that profoundly
altered 20th-century life,” in the
words of Kenneth Bilby, writing in Washington
Post Book World.
THE DAWN OF WIRELESS
It is generally agreed that the first commercial
broadcasting station in the United
States was KDKA, Pittsburgh, which went
on the air in 1920. But what led up to that
launch?
The young Italian-Irish inventor Guglielmo
Marconi arrived in New York in 1899,
after having used his wireless telegraphy
device in 1898 to assist a Dublin newspaper’s
coverage of a regatta. James Gordon
Bennett, publisher of the New York Herald,
knew of this and offered Marconi $5,000 to
cover the America’s Cup yacht races for the
Herald. Marconi accepted, and, primitive as it
was, this could be thought of as the dawn of
wireless, electronic communications media.
While Marconi’s invention
was a spark-gap transmitter
(which essentially
emitted bursts of static) and
an appropriate receiving
device, and could, therefore,
only be used for telegraphy,
others had different ideas.
A young engineer and
academic, Reginald Fessenden,
thought that the sparkgap
transmitter should be
replaced with a device that
emitted a continuous, sustained
wave train, while the
receiver should be a device
that continuously received
this wave train, facilitating
the carriage of speech and
music.
Two early adopters
of wireless were the U.S.
Navy and such companies
as United Fruit Co., which
depended on fast communications
with ships at sea.
The third group of early
adopters was amateur radio
operators. Their numbers
multiplied until, by 1910, amateur radio operators
outnumbered both the U.S. Navy and
wireless commercial ship communications.
The widespread adoption by amateurs was
facilitated by the discovery of crystal radiofrequency
detection for receivers. Interestingly,
it was the building of a crystal receiver
that fueled this author’s interest in the field,
although it was much later than 1910.
The first radio broadcast in American history
was done by Fessenden on Christmas
Eve of 1906. It included speaking, singing,
and violin-playing by Fessenden himself, and
phonograph music; and it was principally
aimed at ships equipped with his apparatus.
As the amateur communications hobby
flourished, at some point Westinghouse, an
early manufacturer of radio hardware, decided
they could sell more receiving sets
if they were to broadcast programming for
them. At 8 p.m. on Nov. 2, 1920, the newly
licensed Westinghouse station, KDKA, Pittsburgh,
broadcasting at 360 meters (approximately
833 kHz; KDKA now broadcasts on
1,020 kHz), went on the air and broadcast
the election results, setting off a “broadcasting
boom” over the next one-and-a-half years.
These, then, are the ultimate roots of the
business we work in. Douglas’ book is a very
complete and interesting historical account
of how American broadcasting emerged
from Marconi’s wireless, and the discoveries
and achievements that preceded it. It is also
a very good accounting of the technologies
that were used and developed during that
period.
If you work in radio or television technology,
you really owe it to yourself to read this
book, to learn where your industry came
from.
