radio
, a form of
mass media
and sound
communication
by
radio wave
s, usually through the
transmission
of
music
, news, and other types of programs from single broadcast stations to multitudes of individual listeners equipped with radio receivers. From its birth early in the 20th century, broadcast radio astonished and delighted the public by providing news and entertainment with an immediacy never before thought possible. From about 1920 to 1945, radio developed into the first electronic mass medium, monopolizing “the airwaves” and defining, along with
newspapers
,
magazines
, and
motion pictures
, an entire generation of
mass culture
. About 1945 the appearance of
television
began to transform radio’s content and role. Broadcast radio remained the most widely available electronic mass medium in the world, though its importance in modern life did not match that of television, and in the early 21st century it faced yet more competitive pressure from digital
satellite
- and
Internet
-based audio services.
Based on the human voice, radio is a uniquely personal medium,
invoking
a listener’s imagination to fill in mental images around the broadcast sounds. More readily and in a more widespread fashion than any other medium, radio can soothe listeners with comforting
dialogue
or background music, or it can jar them back into reality with polemics and breaking news. Radio also can employ a boundless
plethora
of sound and music effects to entertain and enthrall listeners. Since the birth of this medium, commercial broadcast companies as well as government organs have made conscious use of its unique attributes to create programs that attract and hold listeners’ attention. The history of radio programming and
broadcasting
around the world is explored in this article.
Radio’s early years
The first voice and music signals heard over radio waves were transmitted in December 1906 from Brant Rock, Massachusetts (just south of Boston), when Canadian experimenter
Reginald Fessenden
produced about an hour of talk and music for technical observers and any
radio amateurs
who might be listening. Many other one-off experiments took place in the next few years, but none led to continuing scheduled services. On the West Coast of the
United States
, for example,
Charles (“Doc”) Herrold
began operating a wireless transmitter in
conjunction
with his radio school in San Jose, California, about 1908. Herrold was soon providing regularly scheduled voice and music programs to a small local audience of amateur radio operators in what may have been the first such continuing service in the world.
The radio
hobby
grew during the decade before
World War I
, and the ability to “listen in” with earphones (as there were no loudspeakers) and occasionally hear voices and music seemed almost magical. Nevertheless, very few people heard these early broadcasts?most people merely heard
about
them?in part because the only available receivers were those handmade by radio enthusiasts, the majority of them men and boys. Among these early receivers were
crystal sets, which used a tiny piece of galena (lead sulfide) called a “cat’s whisker” to detect radio signals. Although popular, inexpensive, and easy to make, crystal sets were a challenge to tune in to a station. Such experiments were scattered, and so there was little demand for manufactured receivers. (Plug-in radio receivers, which, through the use of loudspeakers, allowed for radio to become a “communal experience,” would not become
widespread
until after 1927.) Early broadcasters in the United States, such as
Herrold
, would continue until early 1917, when federal government restrictions forced most radio transmitters off the air for the rest of World War I, stalling the growth of the medium.

After the war, renewed interest in radio broadcasts grew out of experimenters’ efforts, though such broadcasts were neither officially authorized nor licensed by government agencies, as would become the practice in most countries by the late 1920s. Early unauthorized broadcasts sometimes angered government officials, as in England, where concern was raised over interference with official government and military signals.
Amateurs
developed the means and simply began to broadcast, sometimes preannounced but often not. As they became more
proficient
, they would announce schedules?typically an hour or so for one or two evenings per week.
One of the world’s first scheduled radio broadcast services (known as PCGG) began in Rotterdam,
Netherlands
, on November 6, 1919. Other early Dutch stations were operated by the Amsterdam Stock Exchange (to send information to new members) and by a
news agency
that was seeking a new way to serve newspaper subscribers. Another early station appeared in
Canada
when station XWA (now CFCF) in Montreal began transmitting experimentally in September 1919 and on a regular schedule the next year. (The first commercially
sponsored
stations in Canada appeared in 1922.) The first British station offered two daily half-hour programs of talk and music from Chelmsford (near London) in 1919?20. Concerns about interference with military wireless transmissions, however, led to a shutdown until 1922, when government-authorized stations appeared, including the first London-based outlet. The first Mexican radio station aired in the capital city in 1921, though many in the country had first heard broadcasts from Cuba or
Puerto Rico
. By that point, stations had also appeared in Australia (Melbourne, in 1921),
New Zealand
(from Otago University in Dunedin, also in 1921), and Denmark (from Copenhagen, 1923).

Broadcasting got an important boost in the huge American market when about 30 radio stations took to the air in different cities in 1920?21. Most of these developed out of
amateur operations
, each dedicated to a different purpose. “Doc”
Herrold
returned to the air in 1921, but he soon had to sell his station for lack of operating funds. The
University of Wisconsin
’s
WHA began as a physics department transmitter, but as early as 1917 it was sending wireless
telegraph
agricultural market reports by
Morse Code
to Wisconsin farmers. WHA, the first American educational outlet, probably began voice broadcasts in early 1921, though several other universities soon initiated stations with similar aims.
KDKA
in Pittsburgh, most often
cited
as the first radio outlet in the United States, had begun as the amateur station 8XK in 1916, but it was forced off the air in World War I. It reappeared on November 2, 1920, as a “commercial” voice-and-music service operated by the
Westinghouse
electrical manufacturer to help sell the company’s radio receivers. Westinghouse added other stations in different cities over the next two years, and
General Electric
and the newly formed
Radio Corporation of America
(
RCA
) soon entered the radio business as well. Detroit’s amateur operation 8MK (which debuted on August 20, 1920) soon became WWJ, the first station to be owned by a newspaper (
The Detroit News
). Initially seen as simply another press-supported
community
service, a radio station became a means of hedging bets in case the new medium proved competitive with newspapers.
Slowly, other American stations took to the air, often as
auxiliaries
to the owner’s primary business, such as a retail store, hotel, or record shop. The
deluge
came in 1922 when more than 550 new stations crowded onto the few available frequencies to build on radio’s appeal across the country. Many quickly disappeared as they could not pay the cost of operations (on-air
advertising
was rare). Equipment was largely hand-built, and most stations operated with less power than an ordinary reading lamp. Initial studio spaces had walls covered in burlap to deaden sound and, along with a
microphone
, featured a piano that could be used for filling short bits of air time. A few stations experimented with telephone lines to allow two or more outlets to carry (or “network”) an occasional presidential address or sporting event. Audiences were
enthralled
as radio became a national craze. Magazines, books, and even movies featured or included references to radio broadcasting.
Most other industrial nations began radio broadcasts by the mid-1920s. France (in Paris) and the
Soviet Union
(in Moscow) aired broadcasts in 1922. The first continuing Chinese radio station appeared in Shanghai early in 1923, when stations also appeared in Belgium, Czechoslovakia, Germany, and Spain. The pace quickened when
Italy
explored radio in 1924, followed by Japan, Mexico, Norway, and Poland in 1925. All these countries varied in how they authorized and organized radio services, with governments usually playing a far more central role than was the case in the United States.
Stations everywhere faced the same basic problem: what to program in order to attract and hold an audience?and how to support a continuing service financially. Radio quickly became popular anywhere signals could be heard, but how best to
utilize
the medium?what to place on the air, or to “
program
”?remained to be seen. Most early broadcasts were characterized by haphazardness, though two attractions quickly stood out: the warmth of the human voice (at first nearly always male) and almost any type of music, classical or popular, instrumental or vocal. Virtually everything on the air was live because recordings were of poor quality. Thus, a speaker or a musician could easily fill time until the next segment appeared. Only after the first few years did the notion of “programs” develop, with specific times and lengths, beginnings and endings.
