TODAY | November 12, 2012
why they do it coming up: let's begin this half hour with the scandal that's shaken the bbc . michelle kosinski is in london with more on this. michelle, good morning to you.
>> reporter: good morning, matt. today the bbc is changing its management structure. two more top bosses have just resigned. the bbc , this bastion of journalistic excellence that's been an example for the rest of the world is going through a really bad time right now. part of its tin tellingity challenged. chaos, crisis, bloodbath and from rupert murdoch 's "the sun" bye-bye chump. even the bbc itself has been forced to report on its own failings. reporters grilling their director general .
>> people will have to answer for what they did, and if they got something wrong, that jobs will be at risk.
>> reporter: finally he resigned.
>> but the honorable thing to do is to step down.
>> the whole thing has been thoroughly traumatic. it really is one of the most serious crises the bbc has ever faced.
>> reporter: it started with jimmy shavelle, the wild eyed, wild-haired bbc star now deceased who police believe may be one of britain's worst sex offenders ever with possibly hundreds of victims over four decades. they say some abuse may have happened on bbc property. bbc was working on an investigative report on this but dropped it sparking allegations against the bbc of a cover-up. their competition ran a piece about savile and then they ran another story of a margaret thatcher era politician. the bbc didn't run that and then later realized it was the wrong man.
>> tonight this program apologizes, a key allegation in a report about child abuse was wrong.
>> reporter: now there's an internal investigation and current and past employees are being questioned over child abuse allegations. the former producer was arrested over the weekend, and the fact that bbc 's prior director mark thompson takes over today as chief of the "new york times" has led to questions there. what did he no and when did he know it calling him appearing willfully ignorant.
>> he first of all said he knew nothing about jimmy savile or any of it and later was told by bbc journalists and add mitt that had and it might be about child abuse and add mitt that had and further that than then he went and questioned senior bbc management to try to find out what had gone on.
>> reporter: thompson has declined our request for an interview but maintained he did not know the details of what the savile investigation was about and probably should have asked more questions. now, all of that and more under deep scrutiny. the head of the bbc 's governing trust said it might be time for a radical overall. britain grew up on the bbc . it's the state broadcaster , also the largest broadcaster here. its level of respect has been impeccable, but now shaken deeply. matt?
