This will really chap O'Reilly's hide

It's like a red hot falafel up the wazoo. From King One Eye in a Diary at Kos:

In the key demographic group of viewers aged 25-54, the Total Day ratings for MSNBC rose 47% while Fox declined -13%.

Fox's Prime Time erosion was even greater at -21%. In fact, in every hour in the daypart, from 3:00pm till midnight, Fox numbers were lower. This is a distinction that only Fox, of the five nets surveyed, was able to achieve.

The largest decline was suffered by Greta Van Susteran's On The Record (-22%), followed closely by O'Reilly (-21%). Hannity & What's His Name took the Bronze (-17%). Of the MSNBC programs opposite those losers, Olbermann's Countdown was the biggest gainer (55%), which I'm sure doesn't bother O'Reilly at all.
