Before pirate radio ships began broadcasting off British shores, young people liked to tune in to the English language service of Radio Luxembourg, a commercial station broadcasting from the Grand Duchy of Luxembourg, with the most powerful radio transmitter in the world. It billed itself as 'the station of the stars'. It is nowadays known in most non-English languages as RTL (for Radio Television Luxembourg).
The service was an effective way to advertise products by circumventing British legislation which until 1973 gave the BBC a monopoly of radio broadcasting on UK territory and prohibited all forms of advertising on domestic radio. With a much more populist style than the BBC Light Programme at the time, and with a far greater recorded music content since it did not have the quota of live music forced on the BBC by the powerful unions, it attracted large audiences in Britain, though the reception (208 on the medium wave dial) could often be dodgy.
One of the most memorable advertisements was Horace Batchelor's 'infra-draw' method of winning the football pools. Batchelor, from Keynsham Bristol, claimed to have won the 'treble chance' more than one hundred times, and that he could do the same for those who followed his method. There is no recorded evidence that he provided much in the way of success for his customers, though the advertisement did at least teach them how to spell 'Keynsham'.
