Regular Radio Broadcasting
It was in 1906 when the first human voice was transmitted by radio wave.
Within a mere decade, the worlds first radio broadcaster (KDKA
Radio) appeared in Pittsburgh, the United States (1920). On the first
day of its broadcast, it provided a flash report on the voting results
of the U.S. Presidential Election and the election of the Republican
candidate Harding. It is estimated that approximately 15,000 receivers,
mostly those of amateur radio operators, could have listened in at the
time. Radio quickly became popular, the number of receivers growing
to 5 million two years later.
In Japan, radio broadcasting commenced at 9:30 a.m., on March 22, 1925.
Two years after the Great Kanto Earthquake, JOAK, JOAK, J, O,
A, K, This is the Tokyo Broadcasting Station, the first radio
address broadcast in Japan, filled the skies of Tokyo from a temporary
broadcasting station in Shibaura, Tokyo. The broadcast started with
initial contracts for the receiving audience, which numbered approximately
3,500. Radio broadcasting was also started in Osaka (June 1) and Nagoya
(July 15) in the same year. The fact that broadcasting had begun immediately
after the Great Kanto Earthquake (1923) contributed greatly to helping
people in Japan to understand the importance of receiving reliable information
via broadcasting. However, broadcast stations at that time had a low
output power, resulting in a limited area of clear reception within
Tokyo (output power was only 220 W).
Great Dreams and Roles of Broadcasting
In his address at the opening ceremony for the broadcasting station,
Governor Shinpei Goto of the Tokyo Broadcasting Station gave a famous
speech regarding the function of broadcasting, saying: I cannot
imagine our cultural life of the future without broadcasting.
He entrusted great dreams and roles to broadcasting.
In July 1925, the Tokyo Broadcasting Station commenced regular broadcasting
from a new station located at Atagoyama (1-kW output power). The mystery
of broadcasting, with its invisible radio waves limitlessly expanding,
moved listeners. Broadcasting was proclaimed to be evidence of a new
of Nippon Hoso Kyokai: 1926
