context_page_description: The UK Singles Chart is the official record chart in the United Kingdom. In the 1970s, it was compiled weekly by the British Market Research Bureau on behalf of the British record industry with a one-week break each Christmas. Prior to 1969 many music papers compiled their own sales charts but, on 15 February 1969, the BMRB was commissioned in a joint venture by the BBC and Record Retailer to compile the chart. BMRB compiled the first chart from postal returns of sales logs from 250 record shops. The sampling cost approximately £52,000 and shops were randomly chosen and submitted figures for sales taken up to the close of trade on Saturday. The data was compiled on Monday and given to the BBC on Tuesday to be announced on Johnnie Walker's afternoon show and later published in Record Retailer. However, the BMRB often struggled to have the full sample of sales figures returned by post. The 1971 postal strike meant that data had to be collected by telephone but this was deemed inadequate for a national chart, and by 1973 the BMRB was using motorcycle couriers to collect sales figures.
context_section_description: ^A long debate has persisted that the Sex Pistols out-sold Sir Rod Stewart's double A-side (a budget single) in June 1977, with their anti-Monarchy anthem "God Save the Queen", during the week of Queen Elizabeth II's Silver Jubilee. On the official UK Singles Chart used by the BBC, it was placed at no. 2, and was banned by the national broadcaster and the Independent Broadcasting Authority, which regulated Independent Local Radio, as it was felt that it might cause offence. In more recent years, however, the BBC have tacitly admitted that the song did indeed reach the top of the chart, although this has never been definitively confirmed, with the BBC and sources close to Virgin Records' owner Richard Branson both confirming and denying it as fact.
