Théâtrophone [SEP] Similar systems
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.
