The radio as a media of communication focuses mainly on the nature of what it represents as a media and that others do not possess. One of the strengths of radio is that its production cost is lower than other media, allowing us to use it creatively using voices, music and communicators.

The development of a propaganda slot should be designed as part of a set of elements on the subject embodied in the programming which can be secured as an extension of the campaign created to be placed on the radio.

Digital technology has been incorporated on the radio as part of the production process, but this new technique has not gone beyond that moment of its acquisition in many cases. The analog format is still incorporated into the radio creators’ mind and thoughts.

The emergence of the radio was a solution to the need for communication  at long distances in order to spread knowledge since the method used before was too slow and was not connected to development.
