Brazil's top presidential candidates, Luiz Inácio Lula da Silva and Flávio Bolsonaro, beginning Friday will seek to draw votes through free advertisements on television and radio stations, which continue to play a fundamental role in the campaign despite the rise of social media, experts say.
Even in a heavily online country such as Brazil, ads on the TV and radio continue to set the talk of the town and sway voters, reaching remote corners of the continental-sized country.
