de S.Paulo supported the coup that overthrew President João Goulart, and his replacement by a military junta; the military role would be only temporary—or so at least it was thought. After the financial and business hardships were left behind, the new management started to concentrate on industrial modernization and in creating a distribution network that would facilitate the circulation leaps that would follow. The company bought new printing presses and equipment in the United States. In 1968, Folha became the first Latin-American newspaper to adopt the offset printing system. In 1971, it pioneered a new innovation: lead typesetting was replaced by cold composition. The newspaper's circulation was improving and its share in the advertising market was growing. Late in the 1960s, Frias even formed the nucleus of a national TV network, adding to TV Excelsior, which led in audience in São Paulo and he acquired in 1967, three other stations in Rio de Janeiro, Minas Gerais and Rio Grande do Sul.

That was followed by an article on the news bulletin of ALN, a guerrilla group, in which Frias was classified as an enemy of the organization and Brazil. The bad blood between the newspaper and the left wing groups deepened and reached a climax with the editorial "Political Prisoners?", published in 1972, in which the newspaper challenged the notion that there were people jailed for their political ideas in Brazil.

The editorial claimed: "It is well known that those criminals, whom the daily [Estado] wrongly qualifies as political prisoners, are just bank robbers, kidnappers, thieves, arsonists and murderers, acting sometimes with more exquisite perversity than those other, lowly common criminals, that the media outlet in question thinks deserving of all promiscuity".
