British influence extended globally through its colonies and its informal business relationships with merchants in major cities. They needed up-to-date market and political information. The "Diario de Pernambuco" was founded in Recife, Brazil, in 1825. "El Mercurio" was founded in Valparaiso, Chile, in 1827. The most influential newspaper in Peru, "El Comercio", first appeared in 1839. The "Jornal do Commercio" was established in Rio de Janeiro, Brazil, in 1827. Much later Argentina founded its newspapers in Buenos Aires: "La Prensa" in 1869 and "La Nacion" in 1870.
