Like all the other cultural industries, radio finds itself in the middle of a digitalisation process. However, in contrast to the other industries, digitalisation of radio distribution has practically come to a halt, at least via its traditional broadcasting methods. The failure of DAB (Digital Audio Broadcasting) in Spain to digitalise FM broadcasts has made radio into analogue's last stand. In this paper, we have classified the formats in accordance with the model most used in Spain. It is one that can be understood by a European readership. That is why we use the terms News/Talk (better known in Spain as Generalist or Conventional programming) and Specialised which includes both radio based on a hot-clock (music, all-news) as well as those similar to news/talk shows but that focus on single subjects (sports, finance, youth-oriented or religious programming). As has been stated, the starting hypotheses of this research were structured around four axes: ownership, geographical coverage, format and whether a station belongs to a communication group, or is independent.
