GMG Radio has noticed that the average age of a Radio 1 listener is drifting upwards again, and aren't happy:
Stuart Taylor, chief executive of GMG Radio, said: "The trust has asked them to do something that they are patently not doing. The question is: what happens now?Really, Stuart? Is that what would happen, or - as is more likely - would Radio 1 merely request a change of format, which Ofcom would be minded to approved. You know, like if a Jazz station suddenly started playing Smooth music, that sort of thing?
"If Radio 1 was regulated by Ofcom and not the trust – if we were doing this – then it would be a breach of our licence and we would be taken off air."
GMG claims that the average age of a Radio 1 listener has risen from 29 to 32 over the last three years. Spookily, in that time, a 29 year-old would have become 32.
It looks like the real problem - if you want to see it as a problem - is Chris Moyles, whose audience is larger than others, and also attracts a bunch of older listeners.
However, there is an aspect that Taylor seems to be missing: a lot of breakfast radio listening is done round toasters and on school runs; the price of producing a programme which attracts more teenagers might well be the collateral damage of their parents listening.
