 However, according to historian Gilberto Maringoni, due to president Collor's party's inability to maintain a majority in congress and confrontations with a vocal faction of the country's corporate interests, president Collor himself caused the eventual change in tone of the national press.Brazil's economic crisis with the return of hyperinflation, the confiscation of Brazilians' bank savings, and the intense investigative journalism of the press precipitated the grass-roots social protests that culminated with president Collor's impeachment.In March 1994, Rede Globo aired on the TV news program "Jornal Nacional" the right of reply obtained by the then governor of the state of Rio de Janeiro, after a two-year legal battle.
