Radio is seen as one of the most important inventions of mankind since the beginning of the 20th Century and called "the magic box" in the entire world. Even though it could be considered that radio has been losing its popularity against the rapid technological development of the 21st Century, it is still popular and widely used. Radio has been used for several purposes such as the instrument of information, entertainment, propaganda and so forth. Several states facilitated the radio as the easiest way to get in touch with the society rather than the newspapers and the magazines. Particularly, radio was used as the means of propaganda in times of the World War II. At the same time, the authorities also enjoyed the power of radio in Turkey from the beginning of the 1920' s. The radio was a crucial instrument for construction of the new regime and introduction of the governmental policies. The radio as a public institution was under the state control for several years and the programmes broadcasted with political, social and cultural content were all simply served for the introduction of the new order.
