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.

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.
