The term télécommunication was adopted by the Convention Internationale des Télécommunications at Madrid in 1932 (the official language at the conference was French). The definition then accepted (‘toute communication télégraphique ou téléphonique de signes, de signaux, d'écrits, d'images et de sons de toute nature, par fil, radio ou autres systèmes ou procédés de signalisation électriques ou visuels (sémaphore)’), in so far as it includes non-electrical means of communication, is no longer applicable.
