I really can't fathom why it's believed there is an even greater audience for conservative blowhards on afternoon radio. Clearly many of the radio stations who carry O'Reilly didn't really think there was, as they demanded substantial "Talkola" payments to do so.
The same can be said for MSNBC - since choosing to go 100% Fox Lite their prime time ratings have dropped from a 1.5 to a .5 - they're barely on the meter anymore.
And, CNN continues to lose the war. Aside from Crossfire, they don't have a single liberal host, unless we define liberal as "not conservative." On the right we have Jack Cafferty, Judy Woodruff, Lou Dobbs, Paula Zahn, Wolf Blitzer, Kyra Phillips, Bill Schneider, Jonathan Karl, Candy Crowley...
