On this day in 1925, after a concerted government effort to subsidise the nascent technology following the successful, pioneering launch of KDKA in 1920 out of Pittsburgh, radio broadcasting began with the announcement of the above call letters for station identification from a studio Tokyo, a simulcast with transmitters in Osaka and Nagoya. The inaugural programme featured a live performance by the naval band and a recording of Beethoven’s opera Fidelio. Early broadcast included educational lessons, coverage of baseball games and radio calisthenics—see previously.
