BBC audience under 30 has slumped over the last few years with most younger folk opting for social media, news feeds, Netflix, Sky and other on demand channels.
The BBC is left with older audiences brought up on a diet of limited channels, quality drama, factual, and authorative news. Older viewers outnumber young by a factor of 2:1.
BBC are not stupid - they know that their older audience will diminish over time as the grim reaper does his work.
In an effort reverse decline, they have made the decision to "revitalise" their output - cue the young, culturally diverse, gender equalised, virtuous etc. I'm not convinced it is working - but perhaps their efforts will bear fruit over the next few of years.
It is evident part of their older audience feel alienated and uninterested. They are becoming more tech savvy and changing behaviours to mirror the early adopter younger audience.
In a media market place with several dozen of broadcasters (good and poor) all trying to secure an audience, the BBC has no chance of dominating the airwaves as they once did. It needs to specialise in that at which it excels and drop the rest.
