Towards the end of 1970, the workers of Editorial Zig-Zag went on strike in order to push for the nationalization of their publishing house. On February 12, 1971, the Unidad Popular government took control of 40% of the company's assets, leading to the creation of the "Empresa Editora Nacional Quimantú" (National Quimantú Publishing Company, Ltd.). It was run by Joaquín Gutiérrez, a Costa Rican close to President Allende.
