Although wideband FM is widely used today it took many years for its advantages to be discovered, previously everyone had tried to improve its performance by reducing the bandwidth. It was Edwin Armstrong who made the breakthrough. However it took many years for him to convince people about its superiority. In 1934 he brought his idea to the attention of RCA, and a year later he set up a demonstration. Then in 1939 he used his own money to finance a station to prove that the system worked. Shortly after this the idea began to take off and by January 1940 150 applications for FM broadcast stations had been submitted in the USA. In 1954 the BBC launched its wideband FM service.
