Globo, launched a few months after the 1964 coup, created the first true national network by the late 1960s. Censorship of news was extensive under the military governments between 1966 and 1978, but it also encouraged national television program production. In the early 1970s, several government ministers pushed the commercial networks to develop more Brazilian programming and reduce reliance on imported programs, particularly those with violent and sexual content. While Globo adopted an international model for operations, 90 percent of its content was produced in Brazil.
