NBC Symphony Orchestra
The NBC Symphony Orchestra was a radio orchestra conceived by David Sarnoff, the president of the Radio Corporation of America, especially for the conductor Arturo Toscanini. The NBC Symphony performed weekly radio concert broadcasts with Toscanini and other conductors and served as house orchestra for the NBC network. The orchestra's first broadcast was on November 13, 1937 and it continued until disbanded in 1954. A new ensemble, independent of the network, called the Symphony of the Air, followed. It was made up of former members of the NBC Symphony Orchestra and performed from 1954 to 1963, particularly under Leopold Stokowski.
