At 8 p.m., where Olbermann's Countdown was one of the network's most successful programs, ratings in the first few weeks with Lawrence O'Donnell dropped by about 22 percent versus Olbermann's performance in the fourth quarter of 2010. But O'Donnell's Last Word has regained some of that lost ground, ending February solidly in second place behind Fox News, with a loss among total viewers of just 2 percent versus Olbermann's last month in January.
