The sound of the last tide of Matthew Bannister's Radio One washing away, then, as Jo Whiley and Edith Bowman are eased to one side in a new Radio One line-up:
The Radio 1 controller, Andy Parfitt, said: "BBC Radio 1 must continue to change to connect with a new generation of audiences and this is a significant move, promoting three of our up and coming broadcasters into the heart of the schedule."
Aha, so it's about moving out the older presenters for some new, fresh names, is it?
Not quite, as they're bringing in Greg James and Fearne Cotton to daily slots.
Fearne Cotton is 28, so only a little younger than Bowman; Bowman is 34 and actually younger than Chris Moyles.
To be fair, Whiley had started to turn into a fixture of the Simon Bates sort in mid-mornings, and probably is at the point of needing to move on. It's disappointing, though, that Radio One have chosen to abandon any pretence of being interested in music during the daytime in favour of a woman who feels much more Variety Club Showbusiness Awards than Camden Crawl.
Greg James is probably more surprised than anyone at this promotion, given that he actually has the words "sitting in for" on his driving licence. He's one of those people who crop up in radio a lot, with two first names and an ability to fill the unforgiving minute with just enough chat to take us up to the news, weather and travel. Adrian John. Paul Jordan. One of those.
It all makes for the most crushingly lightweight daytime Radio One schedule since Mike Smith and Gary Davies were alive.
