This article explores the Brazilian Blogosfera Progressista (Progressive Blogosphere, hereafter BP), a leftist political communication initiative aiming to conciliate an institutionalized model of organization with a networked model of action. Despite the disparity of resources existing between them, BP proved able to counter effectively the mainstream media’s political framings, thanks to wise networking strategies, which explored the communicative opportunities offered by social media. The Centro de Estudos de Mídia Alternativa Barão de Itararé – Barão de Itararé Alternative Media Studies Center – is an essential piece in this schema, as it works as a coordinating agency for BP members and trains new participants. Our article intends to discuss this and other characteristics of BP as a group, and the challenges it faces at the present, after the rise of Jair Bolsonaro to Brazil’s presidency.
