Atlântico Sul FM

Founded in 1989 by the Grupo Cidade de Comunicação, Atlântico Sul FM's main focus was the A and B class audience that listened to Casablanca FM, a highlight in Fortaleza's adult contemporary segment, which at that time had switched its focus to young people (CHR) in order to gain a larger audience. To this end, the station's former artistic coordinator, Américo de Souza, was hired.^[2] As a result, the radio station adopted a more segmented style, focusing on musical genres that were rarely covered on other commercial radio stations.^[1] The station's journalism prioritized economic, fashion, health and current affairs issues, also giving way to the social columnism of print journalism.^[2]

In 1999, the station was integrated into the D&E Entretenimento group, as were the radio stations Cidade 99 and the Jovem Pan FM affiliate.^[2] This partnership was broken up in 2017, when D&E remained responsible only for artistic management. In January 2018, Grupo Cidade took full control of the station.
