Definition

The radio was the first device to communicate to mass audiences.

In 1922 the BBC was transmitting only to the London area, by 1925 it was broadcasting to the whole of the UK. The BBC received its Royal Charter in 1927.

When World War II began, the BBC stopped TV broadcasting so that transmissions could not be used as a beacon by enemy aircraft; only radio covered the war. By the late 1960s and early 1970s FM commercial, national and regional radio stations started broadcasting, providing more programme choices for the listener.

By 2000 radio had expanded into the satellite and internet markets.
