Théâtrophone ("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. Subsequently, in 1890, the invention was commercialized by Compagnie du Théâtrophone, which continued to operate till 1932.
The origin of the théâtrophone can be traced to a telephonic transmission system demonstrated by Clément Ader at the 1881 World Expo in Paris. The system was inaugurated by the French President Jules Grévy, and allowed broadcasting of concerts or plays. Ader had arranged 80 telephone transmitters across the front of a stage to create a form of binaural stereophonic sound. It was the first two-channel audio system, and consisted of a series of telephone transmitters connected from the stage of the Paris Opera to a suite of rooms at the Paris Electrical Exhibition, where the visitors could hear Comédie-Française and opera performances in stereo using two headphones; the Opera was located more than two kilometers away from the venue. In a note dated 11 November 1881, Victor Hugo describes his first experience of théâtrophone as pleasant.
In 1884, the King Luís I of Portugal decided to use the system, when he could not attend an opera in person. The director of the Edison Gower Bell Company, who was responsible for this théatrophone installation was later awarded the Military Order of Christ.
The Théâtrophone technology was made available in Belgium in 1884, and in Lisbon in 1885. In Sweden, the first telephone transmission of an opera performance took place in Stockholm in May 1887. The British writer Ouida describes a female character in the novel Massarenes (1897) as "A modern woman of the world. As costly as an ironclad and as complicated as theatrophone."
In 1890, the system became operational as a service under the name "théâtrophone" in Paris. The service was offered by Compagnie du Théâtrophone (The Théâtrophone Company), which was founded by MM. Marinovitch and Szarvady. The théâtrophone offered theatre and opera performances to the subscribers. The service can be called a prototype of the telephone newspaper, as it included five-minute news programs at regular intervals. The Théâtrophone Company set up coin-operated telephone receivers in hotels, cafés, clubs and other locations. It used to charge 50 centimes for five minutes of listening. The subscription tickets were also issued at a reduced rate, in order to attract regular patrons. The service was also available to home subscribers.
Many technological improvements were gradually made to the original théâtrophone system. The Brown telephone relay, invented in 1913, yielded interesting results for amplification of the current.
Similar systems elsewhere in Europe included Telefon Hírmondó (est. 1893) of Budapest and Electrophone of London (est. 1895). In the United States, the systems similar to théâtrophone were limited to one-off experiments. Erik Barnouw reported a concert by telephone that was organized in the summer of 1890; around 800 people at the Grand Union Hotel in Saratoga listened to a telephonic transmission of The Charge of the Light Brigade conducted at Madison Square Garden.
The Eça de Queiroz novel A Cidade e as Serras (1901) mentions the device as one of the many technological commodities available for the distraction of the upper classes.
