Radio broadcasting is a public service with a great impact on the social development of Colombia. Its objective is to guarantee the right to information, recreation, free expression, and personality development. In Colombia, the radio broadcasting service covers almost all the country, this somehow reduces the existing gap in populations that are not digitally connected. This paper proposes an exploration of the current state of radio broadcasting in Colombia and digital radio broadcasting in the world, to review the possible implementation of this technology, so its focus is informative. In addition, it is intended to analytically compare the penetration of new digital radio broadcasting technologies in the world with respect to the penetration in Latin American countries.
