With a career spanning over five decades, Dines directed and launched several magazines and newspapers in Brazil and Portugal.

He was also the director of Grupo Abril in Portugal, where he launched the Exame magazine.

After years of dodging the military dictatorship censorship as the editor in chief of Jornal do Brazil, Dines was fired in June 1974 for publishing an article criticizing the overtly amicable relationship between the owners of the newspaper and the state government of Rio de Janeiro.

In addition to working as a journalist, Dines has written over 15 books, including Death in Paradise, the Tragedy of Stefan Zweig (1981) and Fire Links – Antônio José da Silva, the Jew and other stories of the Inquisition in Portugal and Brazil (1992).

In April 1996, Dines launched the groundbreaking Observatório da Imprensa website.
