Re: So THAT explains it!
I think the BBC got so fed up of the criticism that they got for doing a good job and dominating news, sport and weather that they just decided to give up. And then there was that whole "we've got loads of video, let's force it on people whether they want it or not" redesign.
Stupid ideas like introducing hot desking, moving to Salford and equal pay for the useless and the competent didn't help retain the good staff.
Most of the people who did the good work have gone now and headed over to News International.
