History
IBOPE was created in 1942 by the radio broadcaster Auricélio Penteado, owner of Radio Kosmos in São Paulo. In that year, he decided to apply research methodologies he had learned while studying in the United States under George Gallup, the founder of the American Institute of Public Opinion, in order to quantify the size of the audience of his broadcast in Brazil. When he measured the radio audience in São Paulo, Auricélio proved that Radio Kosmos wasn't among the most listened to stations. Therefore, he would dedicate himself exclusively to research. In 1950, Penteado leaves the presidency of the company in charge to a group of directors.[5]
