She will replace Andy Harries,who yesterday revealedhe is transitioning to Executive Chairman.

We were all kept in the dark.

She has been unofficially acting up in recent weeks after Moore injured herself on holiday.

Charlotte Moore has done more for the BBC and the TV industry than almost anyone will ever realize.

Those endless problems will soon be a thing of the past for Moore.

Jobs like this dont come around very often.

Moore earned 468,000 ($590,000) last year.

And would Netflix mount a rearguard action to keep its prized executive?

Cant see her doing that, was the verdict of one well-connected television executive.

Its arguably a much better fit for Zai than his current role, noted this source.

Nevertheless, it would still be surprising if Bennett was to move so early in his BBC Studios tenure.

Lack of drama experience would be the main factor counting against Phillips.

The more pertinent question is: is the job big enough for Hunt?

Sources say she will be among the favorites when the same vacancies open up again.

In the meantime, Hunt can point to Apple success stories includingSlow HorsesandBad Sisters.

Does he have the appetite for another major role?

People have their doubts.

And perhaps more to the point, is he the right fit for the BBC?

His hit list includesAll Creatures Great and SmallandMichael Palin in North Korea.

As with Moore, he was originally a docs commissioner and would be an experienced hand.

He is thought, however, to be happy at Banijay, with no plans to move.

He is also no stranger to the BBC having editedNewsnightin a past life.

OutsidersOther names are circulating the rumor mill this afternoon.

CouldLiam Keelanfollow up running Disneys EMEA content with a tilt at Moores role?

He is well-liked and has vast experience working for the BBC.

Mystery CandidateIf the BBC casts its net wide, would it look to America for a big-hitter?

There may well be a dark horse not among todays speculation.
