Radio: Borderless and selective On the use codes in radio broadcast

The universal radio In the beginning of the 21 st century, the Internet may be heralded as the great bringer of free information to all, but in the earlier parts of the 20 th century this role appointed to the great new invention, the radio. In Denmark, the earliest experiments with radio broadcasting started as private initiatives in the 1910s and 1920s. By 1925, the state took over responsibility for the broadcasting of radio and established Den Danske Statsradiofoni (The Danish State Radiophony). Thereby, a monopoly was built which was maintained until the 1980s.
