have had smoother leadership transitions than "the tonight show" with its hosts. nbc had to shell out $45 million to get rid of conan o'brian and reinstall jay leno. then there was a battle between leno and david letterman. chronicled so memberorably in the late shift by bill carter who broke this latest scoop for the "new york times" and joins us now on the phone. bill, thanks so much for joining us. you know the story inside and out. why not make fallon go to los angele why move the show to new york? >> well, that really, jake, is the big news here. the idea that jimmy was getting the show was kind of out there because jay has got one contract that he's working on. he's 62 so there was, you know, an expectation he would be leaving soon if not this contract then maybe another year. so jimmy getting the show was kind of expected. what is really surprising is the move back to new york. though there are a lot of reasons for it i think they all feel the energy of new york helps fallon.
