Rihanna's Talk That Talk album has taken the Official Albums Chart No.1 spot on weekly sales of less than 10,000 units.
According to Music Week analysis, it's the first time an album has gone to No.1 on such meagre sales since modern records began - when Millward Brown began supplying data to the Official Charts Company in 1994.
Its sales figure of 9,578 copies smashes the record for the lowest weekly sale for a number one in the 21st century.
Music Week charts analyst Alan Jones writes that the previous low of 13,430 sales was set by Emeli Sande's Our Version Of Events when it returned to number one 11 weeks ago.
In 967 weeks since Millward Brown started compiling data for OCC in February 1994, it is the first time an album has been number one on sales of less than 10,000. The previous low: 11,981 set by The Cranberries' Everybody Else Is Doing It, So Why Can't We? 947 weeks ago.
