Most Brazilian newspapers have regional circulation (usually within State borders). Some newspapers, however, are distributed throughout the country: even if having a local section, these newspapers have a comprehensive coverage of politics, economy and international issues, that make them a source of information for everyone in Brazil.
The four major newspapers are O Globo, Jornal do Brasil, O Estado de Sao Paulo and Folha de Sao Paulo.
The boards (owners) of O Globo and O Estado are more conservative, while JB and Folha are more liberals: however, the opinions are very clearly labeled, as opposed to the factual news. The editorial staff seems to be completely independent: many columnists are published in more than one paper.
