Why Don Imus won't rescue Fox Business

It looks like Don Imus really is headed for Fox Business Network. The crag-faced radio host is parting ways with RFD-TV, the small cable network that has simulcast his show for nearly two years, in what appears to be a precursor to a move to Fox Business, with whom he's reported to be in advanced negotiations.

But will Imus's arrival be a good or bad thing for Fox? That's a complicated question. As I've written, Imus is likely to bring a substantial part of his large following with him to Fox Business. And given FBN's infinitesimal viewership to date, it won't take much of a boost to move the needle.
