By the late 1920s, the "UK government concluded that radio was such a powerful means of mass communication that it would have to be in state control", and gave the publicly funded BBC a monopoly on broadcasting. Because of rigid governmental controls and programming mostly consisting of serious music and highbrow issues, much of the UK population began to turn to radio stations from abroad, such as Radio Lyon, Radio Normandy, Radio Athlone, Radio Mediterranee and Radio Luxembourg, especially on Sundays, when the BBC did not carry any entertainment programmes. However, English-speaking broadcast hours were limited and parts of the UK were unable to receive most stations properly during the daytime.
