Got a cool new tool at work. One of the things I can see are overall ratings.
For Feb. 2011, GSN had an 0.19 full day rating, putting it 39th among all cable channels. The prime time rating was .24, putting it 41th. These are both improvements over the year prior (.16 and .18 respectively). This puts them roughly in the same neighborhood as The Weather Channel, Travel Channel and ESPN2.
The Hub was .04 all day, .05 primetime, putting it in the mid 70s. Comparable networks ratings-wise include Centric and ESPNews.
