BBC executive Danny Cohen is to be the corporation's next director of television.
Mr Cohen, who is currently the controller of BBC One, has been asked to take on the role by director-general Lord Hall as part of a shake-up in senior management roles. Last week former editor of The Times, James Harding, was named director of news.
Mr Cohen, who is not yet 40, has enjoyed a speedy rise in his career, moving from head of youth channel E4 to the controller of BBC3 in 2007.
He switched channels to BBC One in 2010, and has since overseen a string of hits, including Call The Midwife, Ripper Street and The Voice.
His new position, which comes with a salary of £327,800, will see him take charge of the four main BBC channels, along with BBC Films and the BBC archive.
Mr Cohen, who grew up in Edgware, was educated at Rosh Pinah primary school, City of London and then Oxford University. He now lives in Primrose Hill with his wife, economist Noreena Hertz.
He said it was an honour to be appointed as director. "Our ambition is to be the finest broadcaster and producer in the world and our values will be based on talent, creativity, storytelling and innovation."
Lord Hall, recently installed as the BBC's director-general, described Mr Cohen as the "driving force behind an extremely successful period in BBC One's history".
He added: "Key to his success has been an ability to provide viewers with a mixture of high quality programmes they enjoy whilst also introducing them to new subjects they might not have considered before."
Mr Cohen's new role will give him a say in the development of the BBC's digital content, something he has said he sees as likely to become more important in the future.
Speaking to the JC in 2009, he said: "The big question is over how much is going to be on telly and how much on the internet. Will TV and the internet essentially become just one screen in the same box? I think that that is where we will get to. There will still be a schedule but I think on-demand services will become more important."
