Radio Del Plata

In 1970 LS10 Radio Libertad became Radio Del Plata. Together with Rivadavia and Continental, they were the only three private radio stations that operated in Buenos Aires during the last military dictatorship (1976–1983). In 2003, when the radio was owned by Mexican group CIE, Marcelo Tinelli bought the radio station. However, in 2008 he sold it to Grupo Electroingeniería. Osvaldo Acosta and Gerardo Ferreyra are the directors of the business group from Córdoba, who specializes mainly in public works.

Between 2008 to 2015, Radio Del Plata received large amounts of money as official advertising, which conditioned the radio’s editorial line. Yet, after the change in the country’s administration in 2015 and a boom in audience levels in 2016 (the third most popular AM radio), the radio faces a serious economic crisis. Their owners, Grupo Electroingeniería, have kept their agreements with Argentina’s National State (in spite of the fact that both owners are in prison in 2019), but stop investing in the radio station. In 2017 the radio’s main figures left the company as salaries were not being paid; workers’ protests and strikes are frequent (as of 2015).

The radio has a mainly journalistic programming, like most of the AM radio stations surveyed. It features over 40 content affiliates across the country, even though there is no other radio station with such an ownership structure.

Meta Data

There are no audience figures on Radio Del Plata, as the radio station does not hire the services of the only company that measures audience levels in Argentina. However, it is one of the six most popular AM radios in Buenos Aires.
2018 official advertising data were provided by the Secretariat of Public Communications of the Argentinian Presidency’s Chief of Cabinet of Ministers.
