Quick update to this post [1]. Sarah Palin’s Wednesday appearance on Sean Hannity’s show [1] was his second highest-rated this year, according to Nielsen Media Research. The Fox News host pulled in more than 4 million viewers, beating his top-rated colleague Bill O’Reilly (ouch [2]) and everyone else on cable for one night.

Hannity had roughly 4,200,000 viewers, according to Nielsen, including 1,149,000 viewers in the coveted 25-to-54-year-old demo. (On election night, Hannity’s show had 4,224,000 viewers.)

O’Reilly’s Wednesday show was watched by about 3,868,000, including 1,065,000 in the “demo.”

MSNBC’s Rachel Maddow, by comparison, had just 957,000 (273,000 A25-54) while CNN’s Larry King Live had just 835,000 (208,000).

Meanwhile, Palin’s appearance on Monday's “Oprah” [3] gave Winfrey her highest ratings in nearly two years [4].

The show drew an 8.7 household rating and 13 share [5] – the highest ratings for Oprah since she hosted the entire Osmond family on an episode in 2007, according to TV by the Numbers.
