The first trace of a professional linked to radio advertising appears, according to the data provided Cape Verde Email List by their conclusions, in 1926, on Radio Barcelona, the first radio station in Spain. The only thing known about her is that her name was Rosa and that she was the secretary of the advertising department. Even so, her work went beyond management and administration and, from what Espinosa contributes, includes copying and account manager jobs. Rosa wrote the advertising texts that were later read on the air and managed which campaigns had to go on the air.When the radios were starting, male voices were the dominant ones on the air, but that soon began to change. Female voices entered the airwaves. They did it for a question of acoustics (they sounded better) but also for one of targets. Women were the main listeners of the radio, as they were the ones at home during broadcast hours.
In addition, those responsible for the first commercial radio stations to appear in Europe and North America realized that women were a very attractive audience in terms of potential income. They were already the recipients of a large part of the publicity that was published in the press.“Loyalty to women as listeners meant in addition to having a stable audience, opening an easily exploitable commercial line”, explains the researcher in her conclusions.
