context_page_description: The UK Singles Chart is a weekly record chart which for most of its history was based on single sales from Sunday to Saturday in the United Kingdom. Since July 2014 it has also incorporated streaming data, and from 10 July 2015 has been based on a Friday to Thursday week. As of 5 July 2020, 1373 singles have reached number one. The chart was founded in 1952 by Percy Dickins of New Musical Express, who telephoned 20 record stores to ask what their top 10 highest-selling singles were. Dickins aggregated the results into a top 12 hit parade, which was topped by "Here in My Heart" by Al Martino. NME's chart was published each week in its eponymous magazine.
  The sources, in accordance with the official canon of the Official Charts Company, are the New Musical Express chart from 1952 to 1960; the Record Retailer chart from 1960 to 1969; and the Official UK Singles Chart from 1969 onwards.
