Cambio tecnológico en la telefonía de Cataluña durante el monopolio de CTNE, 1924-1936 Authors Ángel Calvo Calvo Abstract Catalonia led the principal episodes of transference of the telephone to Spain, typical phenomenon of the Second Technological Revolution. Before the creation of the monopoly of the National Telephone Company of Spain (CTNE), Catalonia was kept at the top of the Spanish regions in endowment of telephones. This owed basically to the impulse given by the Mancomunitat to the construction of infrastructures of telecommunication. CTNEs appearance in 1924 stamped a substantial draft on the Spanish telephony. This paper analyzes how the program of amplification and modernization supported by CTNE took form when it obtained the grant of the monopoly. The basic support of the paper lays in the sources of the company, especially the Minutes of the Board of Directors and the Minutes of the Managerial Committee.
