List of UK charts and number-one singles (1969–1988)

On 15 February 1969, the BMRB was commissioned in a joint venture by the BBC and Record Retailer to compile the singles and album charts. BMRB compiled the first chart from postal returns of sales logs from 250 record shops.[11] 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 (rebranded Music Week in 1972).[2] 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.[2] A World in Action documentary exposé in 1980 revealed corruption within the industry; stores' chart-returns dealers would frequently be offered bribes to falsify sales logs.[12]

ABBA, who had a total of eleven number-one singles between 1974 and 1982 – nine of which topped the official charts, and an additional two not recognised in the Official Charts Company's canon.

The New Musical Express (NME) chart was the first in the United Kingdom to gauge musics' popularity by physical sales – previously sheet music sales were used. NME's co-founder Percy Dickins imitated the chart produced by American Billboard magazine and began to compile Britain's first hit parade in 1952.[2][13] Other periodicals produced their own charts and The Official Charts Company and Guinness' British Hit Singles & Albums regard NME as the canonical British singles chart until 10 March 1960.[11] After this Record Retailer is regarded as the canonical source until February 1969, when the BMRB was formed. However, during the 1960s NME had the biggest circulation of charts in the decade and was the most widely followed.[2][7]

After 1969, NME continued to compile charts in the 1970s and 1980s and ended its time as the longest running independently compiled in May 1988.[1]

Paul McCartney with wife and Wings band member Linda. McCartney wrote the Wings song "Mull of Kintyre" which was the best selling record of the decade; in 1976 the band had two additional number-ones (one on each of the "other" charts) that are not recognised in the Official Charts Company's canon.

Melody Maker compiled its own chart from 1956 until 1988 which was used by many national newspapers.[2] It was the third periodical to compile a chart and rivaled existing compilers NME and Record Mirror. Melody Maker's chart, like NME's, was based on a telephone poll of record stores.[2][1] Melody Maker compiled a Top 20 for its first chart using figures from 19 shops on 7 April 1956.[2] During the 1950s, sample sizes ranged from around 14–33 shops and on 30 July 1960 the phoning of record shops was supplemented with postal returns; the first chart to use this method sampled 38 stores from 110 returns. On 26 August 1967, Disc, owned by the same company as Melody Maker, stopped compiling their own chart and started using the Melody Maker chart.[14] In its 9 February 1963 edition, Melody Maker disclosed that it received chart returns from 245 retailers and that its chart was audited by auditors supplied by Middlesex County Council.[15] By the end of 1969, however, with the establishment of the BMRB, Melody Maker and NME had reduced their sample pool to 100 stores.[16]

During the 1980s, Culture Club had two "official" number ones, plus two others not recognised in the Official Charts Company's canon.

Top Pops was founded initially as a monthly publication in May 1967. In May 1968 it began compiling a chart based on the telephone sample of 12 W H Smith & Son stores. The charts and paper became weekly the following month. Rebranded Music Now by 1970, the chart and paper ceased publication the following year.[1]

Rick Astley (pictured in 2017) had the distinction of charting the last non-canonical number-one in 1988 with "Together Forever."

On 4 January 1983, compilation of the UK single and album charts was taken over by Gallup who began the introduction of computerised tills which automated the data collection process.[2][11] The chart was based entirely on sales of physical singles from retail outlets and announced on Tuesday until October 1987, when the Top 40 was revealed each Sunday, due to the new automated process.[17] Gallup would continue to compile the single and album charts for a few more years past the elimination of NME and Melody Maker's independently compiled charts after the 14 May 1988 issues and their switching starting the next week to charts compiled by the Market Research Information Bureau.,[1] until 30 June 1990 when the British Phonographic Industry (BPI) terminated its contract with them[18][19] and switched to a new entity, Chart Information Network[nb 1], which would change its name to The Official UK Charts Company in November 2001.
