Record chart

A record chart is a ranking of recorded music according to popularity during a given period of time. Examples of music charts are the Hit parade, the Billboard Hot 100 or Top 40.

Many different criteria are used in different charts, including sales of records, cassettes and compact discs, the amount of radio airplay, and since the introduction of digital technology, the number of downloads and the amount of streaming activity.

Some charts are specific to a particular musical genre and most to a particular geographical location (although download charts are not easily pinned down in this way). The most common period of time covered by a chart is one week with the chart being printed or broadcast at the end of this time. Summary charts for years and decades are then calculated from their component weekly charts. Component charts have become an increasingly important way to measure the commercial success of individual songs.

UK Albums Chart

The UK Albums Chart (currently entitled the Official Albums Chart) is a list of albums ranked by physical and digital sales and (from March 2015) audio streaming in the United Kingdom. It was published for the first time on 22 July 1956 and is compiled every week by the Official Charts Company (OCC) on Fridays (previously Sundays). It is broadcast on BBC Radio 1 (top 5) and published in Music Week magazine (top 75), on the OCC website (top 100) and in UKChartsPlus magazine (top 200).

To qualify for the Official Albums Chart the album must be the correct length and price. It must be more than three tracks or 20 minutes long and not be classed as a budget album. A budget album costs between £0.50 and £3.75. Additionally, various artist compilations – which until January 1989 were included in the main album listing – are now listed separately in a compilations chart. Full details of the rules can be found on the OCC website.

According to the canon of the OCC, the official British albums chart was the Melody Maker chart from 8 November 1958 to March 1960 (although the Record Mirror published charts from 22 July 1956); the Record Retailer chart from 1960 to 1969; and the Official Albums Chart from 1969 on. In the 1970s the new album chart was revealed at 12:45 pm on Thursdays on BBC Radio 1, and then moved to 6:05 pm (later 6:30 pm) on Wednesday evenings during the Peter Powell and Bruno Brookes shows. In October 1987 it moved to Monday lunchtimes, during the Gary Davies show, and from April to October 1993 it briefly had its own show from 7:00–8:00 pm on Sunday evenings, introduced by Lynn Parsons. Since October 1993 it has been included in The Official Chart show from 4:00 – 5:45 pm on Fridays (previously from 4:00 – 7:00 pm on Sundays). A weekly 'Album Chart' show was licensed out to BBC Radio 2 and presented by Simon Mayo, until it ended on 2 April 2007.

United Kingdom

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign state in the European Union. Lying off the north-western coast of the European mainland, it includes the island of "Great Britain" (a term also applied loosely to refer to the whole country), the north-eastern part of the island of Ireland and many smaller islands.Northern Ireland is the only part of the UK that shares a land border with another state—the Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-southwest. The Irish Sea lies between Great Britain and Ireland. With an area of 93,800 square miles (243,000 km²), the UK is the 80th-largest sovereign state in the world and the 11th-largest in Europe. It is also is the 21st-most populous country, with an estimated 64.5 million inhabitants.

The United Kingdom is a constitutional monarchy with a parliamentary system of governance. Its capital city is London, an important global city and financial centre with an urban population of 10,310,000, the fourth-largest in Europe and second-largest in the European Union. The current monarch—since 6 February 1952—is Queen Elizabeth II. The UK consists of four countries: England, Scotland, Wales, and Northern Ireland. The latter three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff, and Belfast, respectively. The nearby Isle of Man, Bailiwick of Guernsey and Bailiwick of Jersey are not part of the United Kingdom, being Crown dependencies with the British Government responsible for defence and international representation.

UK Singles Chart

The UK Singles Chart (currently entitled Official Singles Chart) is compiled by the Official Charts Company (OCC), on behalf of the British record industry, listing the top-selling singles in the United Kingdom, based upon physical sales, paid-for downloads and streaming. To be eligible for the chart, a single is currently defined by the Official Charts Company (OCC) as either a 'single bundle' having no more than four tracks and not lasting longer than 25 minutes or one digital audio track not longer than 15 minutes with a minimum sale price of 40 pence. The rules have changed many times as technology has developed, the most notable being the inclusion of digital downloads in 2004 and streaming in 2014.

The full chart is a Top 200, though the OCC website contains the Top 100 only. Some media outlets only list the Top 40 (such as the BBC) or the Top 75 (such as Music Week magazine) of this list. Around 6,500 British retail outlets contribute sales data, as well as most UK online digital-download stores. Unlike charts in the United States, no airplay statistics are used for the official UK Singles Chart. The chart week runs from 00:01 Friday to midnight Thursday, with most UK physical and digital singles being released on Fridays. From 3 August 1969 until 5 July 2015, the chart week ran from 00:01 Sunday to midnight Saturday.
