The BBC has posted record figures for listeners of its radio on demand and download services, although four of its national digital stations have fewer online visitors than a year ago.

BBC Radio online material notched up a record 12.5 million requests in September, with The Archers once again the most popular show with 682,304 "listens" streamed during the month.

Chris Moyles' show on Radio 1 took second slot with 503,088 listens.

In terms of radio stations, Radio 2 and Radio 3 achieved new peaks in September, with 3.1 million and 475,000 streamed hours respectively.

BBC podcasts also had a record month in September, with 4.8 million mp3 files downloaded.

Radio 4's From Our Own Correspondent podcast saw the biggest year on year percentage increase - 75% - recording 258,534 downloads.

Radio 1's Best of Moyles continues to top the table of weekly podcasts with 574,067 downloads of the weekly show across the month.

However, digital stations 1Xtra, Asian Network, BBC7 and Five Live Sports Extra all recorded fewer unique visitors to their station's websites in September compared with the same month last year.

1Xtra dropped from 408,000 to 340,885 visitors; Asian Network was down slightly from 134,086 to 132,345 users; and BBC 7 fell from 358,913 to 343,197 unique visitors - although the number of listening requests for shows on the station rose year on year from 1.92 million to 2.47 million. The biggest fall was for Five Live Sports Extra, down from 283,966 users last September to 150,000 this year.

However, this year on year decline is probably partly attributable to Five Live Sports Extra's website being busier last September during the victorious climax to England's Ashes cricket campaign.
