En effet, le theatre n'a pas hesite a utiliser le son electrique hors de son enceinte pour son rayonnement, grace au theatrophone
, (33) au theatre radiophonique et au disque qui etaient le fait des artistes de theatre et qui diffusaient des produits sonores issus de la scene.
In 1892, Scientific American Supplement reported on the use of a device called the Theatrophone that had already been in use for two years in Paris, reports the Daily Mail.
The Theatrophone Company would operate from a central venue, which was connected to several secondary stations at other venues.
The theatrophone had three cables, two for transmitting music and the other for an alarm set for five minutes to keep track of the listener's allotted time.
Subscribers received the service in their homes, but theatrophones were set up for enthusiasts to use in hotels, restaurants, vestibules, and cafes throughout the city.
Finally, technological advances were evident in the entertainment industry not only in the use of electric lighting in venues such as the music-hall and cafe-concert, but also in inventions such as the gramophone and the theatrophone
and developments in cinema and photography.
