Postes, télégraphes et téléphones (P&T, PTT, P et T) was the French administration of postal services and telecommunications, formed in 1921. In 1991 it was split into La Poste and France Télécom.
The name Postes, télécommunication et télédiffusion never received official recognition from the French state. It was above all used in French campaigns, in unofficial texts and in film credits. In effect, Télédiffusion, which grouped together television and radio channels, was always independent.
