Needle time was created in the United Kingdom by the Musicians' Union and Phonographic Performance Limited to restrict the amount of recorded music that could be transmitted by the BBC during any 24-hour period. The number of hours per week allowed gradually increased over the years from below 30 hours in the 1950s. Until 1967 the BBC was allowed to play only five hours per day of commercial gramophone records on the air. It continued to affect BBC Radio 1, BBC Radio 2 and the Independent Local Radio stations until 1988. The result was that the BBC had to use "cover" versions of popular songs by groups such as Shane Fenton and the Fentones recorded at the BBC studios, or orchestral versions by one of the in-house orchestras, to fill in the hours.

The "208" shows on Luxembourg were mainly fifteen minutes to thirty minutes in length and presented under names such as the Decca Records Show or the Capitol Records Show. These prerecorded programmes resembled what later became known as infomercials, because they normally only featured a little over half of the record, with heavy plugging for title, artist and label. Because all the hours of transmission were booked up by the major record companies (EMI, Decca, Pye, Philips etc.) groups and artists had to sign to them to get any exposure. This was one of the driving forces for Ronan O'Rahilly and others to start the first pirate radio station to get exposure for artists he represented. The "pirate stations" Unlike the BBC or Radio Luxembourg, the offshore pirate radio stations of the 1960s operated not only outside the
