I stopped listening to Steve Wright five years ago, I just got sick of his shallow, banal, patronising drivel that I presume was inspired by the american radio style. Pity he didn't go over there and stay.
That said I have realised over recent years that my listening habits are changing in similar fashion to my mother who for many years listened to the "light" programme but then as she got older listened less and less.
The BBC like most commercial stations seems to be attuning its programmes to younger tastes so it seems likely I shall stop listening when radio goes digital. I'm rather sad about this but that's life it would seem.
