Broadcasting as a business in the Republic of China began with the establishment by the Ministry of Communications of the Tientsin Broadcast Station at Tientsin, Hopei on May 1, 1927. From that date on various state-run and privately-owned broadcast stations have emerged throughout the country.　　In commemoration of its 30th anniversary and in appreciation of its splendid service to the society, a set of commemorative stamps was issued. The stamps show, in the central design, a globe, a broadcasting tower and a microphone. In the background are radio waves reaching from Taiwan to every part of the world.
