Once first images and sound era ended, the radio reclaimed itself again. A very particular case, in which STIMEY puts great efforts and interest, is the radio for young people.
Although it may result shocking, the capacity of abstraction and imagination is greatly decreased when an auditive element is accompanied by a visual one. But if we want a long-lasting impact, we want the receiver to create his/her own mental image.
As a communicating element which demands low resources on its listeners, radio has no rival.
