June 7 is Journalists Day in Argentina. The Gazeta de Buenos Ayres was organized on June 2, 1810, and the first issue was released on June 7. The Gazeta was published each week afterwards. The date 7 June has been honored in Argentina as Día del Periodista, “Journalist’s Day”, since 1938.
The Gazeta provided information about new laws, the development of the Peninsular War and the Argentine War of Independence. The government ordered that the newspaper be read aloud at chapels after mass celebrations, because of the high illiteracy rate among the population.
It was closed by the minister of government to Buenos Aires, Bernardino Rivadavia in 1821.
