This is the first full week of 2009 ratings and there was no special programming to exclude so all the averages this week are based on five nights of programming.
This week at 8PM, HLN comes out on top in the Adults 25 - 54 ratings demographic. FOX actually had the highest demo three out of the five nights, but when the week was averaged HLN just came out ahead.
FOX gets the week at 9PM, but they shared the top spot this week with CNN on Tuesday night and MSNBC on Thursday and Friday.
During the 10PM hour, CNN was the clear leader having the highest demographic four out of five nights.
When I first started looking at the ratings FOX would frequently have the top demographic rating during any of the prime time hours. Now, FOX still has more prime time wins, but it is not by much: FOX won 6 hours of prime time this week; CNN 5 hours; MSNBC: 2; HLN: 2.
