Théâtrophone (French pronunciation: [teatʁɔfɔn], "the theatre phone") was a telephonic distribution system available in portions of Europe that allowed the subscribers to listen to opera and theatre performances over the telephone lines. The théâtrophone evolved from a Clément Ader invention, which was first demonstrated in 1881, in Paris.
