BBC Radio 1 chart show could move from Sundays
BBC Radio 1's Official Chart show could move from its current Sunday night slot following an international agreement to release albums and singles on Fridays.
From summer 2015, new music will be released at 00:01 on Friday.
The International Federation of the Phonographic Industry (IFPI) hopes an aligned global release day will reduce piracy and "re-ignite excitement".
The Official Charts Company confirmed it would "also be looking to move the UK chart announcement day".
In a statement it said: "Exact details are to be decided, but Radio 1 will continue to be the home of the Official Chart."
A Radio 1 spokesman said a decision had yet to be made on whether the show would move or remain in its current timeslot.
Most new releases currently come out on Mondays in the UK.
The move to a synchronised global release day follows months of discussions between retailers, record companies, artists and musicians' unions.
It means artists will be able to release their music instantly on the same day worldwide, rather than release it on different days in different countries.
According to the IFPI, "retailers internationally are committed to working with the labels and artist communities to ensure the successful implementation of the move to Friday."
Radio 1's Official Charts show, hosted by Clara Amfo, currently runs from 16:00 to 19:00 on Sundays.
Positions on the UK album and singles chart relate to physical sales, downloads and audio streams from Monday to Sunday in any given week.
