Imus still gets quite a few politicos, but, true, it ain't like it was.......I think FBN is a much better fit than RFD-TV, and, if Fox properties can allow Beck to do what he does on FNC, maybe they will let Imus fire his shots more freely...
What could make this work for Fox Business is that when Imus is on his game, he still can be one of the better interviewers out there.....one of the joys of the WFAN/MSNBC broadcasts was how Imus could get politicians, authors, and other soap-box jumpers to say things that other interviewers could only dream about. Combine that with some bone-crushing comedy/parody, and I can see this working.....Give him a better-known outlet, including more frequent appearances on Fox News, and I think this could be successful.
As for format breaking..I remind one and all that MSNBC {which still can't hold a candle to Fox's ratings} is "The Place For Politics...then runs the same 30-40 documentaries about murderers and child molesters most evenings and all weekend long.
Besides, who the hell is watching Fox Business now?
Oh, yeah....radio. Imus was able to overcome so many broadcast/tech obstacles between WFAN, national syndication, and MSNBC by pitching a bitch about it on-air. He still does.
