communication to stand alongside, complement and often rival the
newspapers. China’s first wireless station — the Osborn Radio Station,
known alternatively as XRO and the Radio Corporation of China — had
opened in 1923 in Shanghai. It transmitted from studios on the roof of
the Dollar Building on the Bund with an initial 65-minute programme of
classical and light music as well as some news. The station estimated
that there were 500 wireless sets in the International Settlement

and other major areas where foreigners lived. The station was owned
and established by an American journalist called E. G. Osborn and a
wealthy overseas Chinese. Sun Yat-sen declared himself a fan of the
new media but there simply weren’t enough listeners. Despite moving
