Over the times, the radio product has experienced several stages of evolution, all of them related to the level of development of the field’s technologies and to media market’s requirements. If originally the producers of radio message were concerned about broadcasting messages at a distance, then the basic objective focused on the radio's ability to conserve and broadcast the product over time. This way, certain characteristics of the radio message such as ephemeralness and the impossibility of listening to a particular type of radio product have become history. Thanks to audio podcasts, today's radio products are more accessible and varied. The access to the favorite programs of the media consumer in his free time, not in broadcast time according to the program grid, determines a high degree of public’s loyalty, especially today when people worry about continuous shortage of time.
