Fox News Channel, which continues to dominate the cable news ratings, has something to be concerned about in the year-end ratings, the Associated Press reports.

Fox was the only cable news network to finish the year with a loss of viewers, the story reports.

Fox News’ prime-time viewers dropped 8% in 2011, while CNN rose 17%, helped by a refreshed schedule, the story says. The midterm election in 2010 particularly appealed to Fox’s Republican-heavy viewership, the article notes.

Fox drew 1.87 million viewers on average in prime time during 2011, and Fox had all of the top 13 cable news programs on the air. Fox continued to beat the combined totals for its two main rivals, CNN and MSNBC, in both prime time and total day.

MSNBC, meanwhile, saw its prime-time audience rise 2%, showing that the network survived "the exit of its most popular prime time personality, Keith Olbermann, who defected to Current," the piece points out.

Nevertheless, Olbermann’s 8 p.m. time slot had an 11% decline, the story notes.

Fox saw its total-day viewership fall 5% in 2011.

CNN’s sister channel HLN posted a 20% increase over 2010, boosted in part by the Casey Anthony murder trial.
