The station started its broadcast on September 28, 1969 on the frequency of 590 on the AM band replacing Radio Porteña, originally from its predecessor set up in 1933. Television producer
Televisión Federal S.A, originating in Buenos Aires, acquired the station in the latter years. In January 2021, Argentine businessman Carlos Rosales, owner of Grupo Santamartah, acquired the station, along with
LOS40, from its longtime owner,
Grupo PRISA, to rent the ownership. During 2024, the radio station experienced financial difficulties, resulting in delayed payroll payments to the workers, which led to repeated layoffs. On February 5, 2025, it was confirmed that Carlos Rosales, along with
LOS40 and Urbana Play, of which Continental owns the frequency, sold the radio to Gonzalo Arias, through his audiovisual production company Tronito, while Grupo Octubre (owners of
El Nueve) will provide technical and logistical support. For this reason, the station moved its studios to
Channel 9 headquarters on February 8, 2025, while Los40 will broadcast from
AM 750 headquarters. == Servicio Informativo Continental ==
