History of radio in the Philippines
Transcript of History of radio in the Philippines
First Radio Network
Henry Hermann is the founder of the Electrical Supply Company.
The company started with test broadcasts. Starting with the first broadcast made from Nichols air field (in Subic) by using a five-watt transmitter. Until it blooms to have a 100-watt transmitter, (1924) making KZKZ the second radio station of the Philippines.
All radio programs back in the day were English. They resemble pretty much like those radio shows heard from the continental US. In fact, the sponsorships were also patterned after famous American radio programs like the Listerine Amateur Hour or the Klim Musical Quiz.
Kapisanan ng mga Brodkaster ng Pilipinas
Kapisanan ng mga Brodkaster ng Pilipinas (Association of Broadcasters of the Philippines), the foremost broadcast media organization in the country, composed of owners and operators of radio and television stations (Regular Members) and the radio and television stations themselves (Associate Members).
Call Letters from K to D
KZ was used because the Philippines was then a colony of America. All call letters of radio stations in the US starter either with K or W.
Francisco Koko Trinidad, known as the father of Philippine Broadcasting attended the International Telecommunications Union (ITU) in 1947, held in Atlantic City in the US to propose of usage of RP instead of KZ. But this was denied by the ITU and gave the letter D as a replacement to KZ.
“D” Was Originally for German Stations
Professor Elizabeth Enriquez's research, explained why Philippine radio station call letters start with “D” and why it actually meant Deutschland
or the German name of Germany.
Start of the 20th century
Start of the 20th century the Slaby-Arco wireless system was developed
1900 Reginald Fessenden made a weak transmission
of voice over the airwaves
1901 Marconi conducted the first successful
transatlantic experimental radio
1904 U.S. Patent Office awarded Marconi a patent
for the invention of radio
Using various patents, the British Marconi company was established in 1897 and began communication between coast radio stations and ships at sea. This company, along with its subsidiaries Canadian Marconi and American Marconi, had a stranglehold on ship to shore communication. It operated much the way American Telephone and Telegraphoperated until 1983, owning all of its equipment and refusing to communicate with non-Marconi equipped ships.
The company Telefunken was founded on May 27, 1903, as "Telefunken society for wireless telefon" of Siemens & Halske (S & H) and the Allgemeine Elektrizitäts-Gesellschaft (General Electricity Company) as joint undertakings for radio engineering in Berlin.
The mind behind the amplitude-modulated (AM) radio, so that more than one station can send signals.
In 1909, Marconi and Karl Ferdinand Braun were awarded the Nobel Prize in Physics for "contributions to the development of wireless telegraphy".
April of 1909, Charles David Herrold, an electronics instructor in San Jose, California constructed a broadcasting station. It used spark gap technology but modulated the carrier frequency with the human voice, and later music. The station "San Jose Calling" (there were no call letters), continued to eventually become today's KCBS in San Francisco.

March 8, 1916, Harold Power with his radio company American Radio and Research Company (AMRAD), broadcast the first continuous broadcast in the world from Tufts University under the call sign 1XE (it lasted 3 hours). The company later became the first to broadcast on a daily schedule, and the first to broadcast radio dance programs, university professor lectures, the weather, and bedtime stories.
Harold J. Power
Inventor Edwin Howard Armstrong is credited with developing many of the features of radio as it is known today. Armstrong patented three important inventions that made today's radio possible. Regeneration, the superheterodyne circuit and wide-band frequency modulation or FM.

In 1933, FM radio was patented by inventor Edwin H.

Sri Lanka Radio Broadcasting
Radio Ceylon (1923) is developed into one of the finest broadcasting institutions in the world.
Now known as Sri Lanka Broadcasting Corporation.
Telegraph Department started broadcasting in Ceylon.
Dec.16,1925, a regular broadcasting service came to be instituted.
Edward Harper is Chief Engineer of Telegraph Office. He founded the Ceylon Wireless Club and the Father of Broadcasting in Ceylon.
Canadian Broadcasting Corporation
The Canadian Broadcasting Corporation, officially branded as CBC/Radio-Canada, is a Canadian crown corporation (state sponsored) that serves as the national public radio and television broadcaster. The English- and French-language services units of the corporation are commonly known as CBC and Ici Radio-Canada respectively, and both short-form names are also commonly used in the applicable language to refer to the corporation as a whole.
The financial structure and the nature of the CBC differs from other national broadcasters, such as the British broadcaster BBC, as the CBC employs commercial advertising to supplement its federal funding on its television broadcasts. The radio service employed commercials from its inception to 1974. Since then, its radio service, like the BBC, has been commercial-free. However, since the fall of 2013, CBC's FM Radio Networks Radio 2 and Espace Musique have introduced limited advertising amounting to 4 minutes an hour.
Cuba is a small island of 111,111 square kilometers located on the Caribbean Sea at a very short distance from the US. It is the largest island of the Antilles and was one of first countries in America to have broadcast radio stations.
It all started in January of 1922 when American Telephone and Telegraph (ATT) announced their interest to enter the blossoming radio industry in the US. At that time ATT owned the telephone company of Cuba, known as the Cuban Telephone Co.
In reality this was not the first radio station operating in Cuba. As early as 1920, a community of radio experimenters (amateurs) had introduced radio on the island with a few low power transmitters.
Frank H. Jones, an electrical Engineer, went to Cuba to work in the Sugar Industry and by 1912 installed and operated a 2000 W spark cw transmitter. Then, early in 1922, he operated an experimental radio station from the Sugar Cane Mill, Tiunicu. His ID was a cuckoo bird and his voice "If you hear the CU of the CUCKOO you are tuned to Central Tiunicu."
Other pioneers were Luis Casas Romero, a young man who F.T. Caldwell chief Engineer of PWX sent to Key West to supervise the installation in Club San Carlos (after discovering, during the installation of PWX, that an experimental radio station was on the air in Havana), and Manuel A. Alvarez Alvarez in Caibarien, Las Villas province in the central north coast of Cuba.

KGST did not go on the air until 1949, but it was part of a tradition of Spanish-language broadcasting reaching back to Mexico’s first stations in the 1920s and Spanish-language programs out of Los Angeles in the wake of World War I.
In the 1920s and 1930s, the Mexican state was finally recovering from the 1910 revolution and was institutionally organizing. The government saw broadcasting as a powerful tool for “modernizing the country, establishing political order, and building national cultural integration.” It was particularly suited to Mexico’s landscape. Most Mexicans at that time were rural peasants spread over a huge and varied terrain with little access to national institutions. Broadcasting in Mexico began as a combination of state-run stations and commercial stations that were friendly to the state and were not allowed to criticize the government on the airwaves.
The Mexican government’s failed early efforts at broadcasting are revealing of musical tastes outside of the capital in greater rural Mexico. Most of the immigrants who were to work in the fields of California came from rural areas and brought their tastes with them. Broadcasters in the U.S., freed from the regulations of the Mexican state, tailored their broadcasts to this demographic.
History of Japanese Radio
The first station in Japan was JOAK in Tokyo, opening on March 22, 1925. JOAK was on 800 kHz at 220 watts at first, soon increased to 500 W.
The second station in Japan was JOBK in Osaka, which began operation June 1, 1925.
NHK and the idea of a national broadcasting service was formally incorporated August 20, 1926.
During 1941, Japanese radio audiences had almost 50 local AM radio stations they could listen to for a large part of each broadcasting day.
Since broadcasting officially began in 1925, the original Tokyo Broadcasting Station [JOAK] had been renamed Nippon Hoso Kyokai and by the end of that decade, had created a sophisticated network of landline connected stations across the main islands.
In 1931, a second network had already been completed in the three main centers of Tokyo, Osaka and Nagoya.
Expansion of the network continued in the rest of the decade that followed, not only in Japan itself, but also in occupied territories such as Formosa [Taiwan], Korea, and Manchuria where sometimes quite powerful stations were built.
