My alma mater, CNN, kicked some butt yesterday in its cable coverage of all things inaugural.
Here's the quick data: Nielsen's Fast National data.
11am-2pmET: Total Viewers: CNN - 6,941,000
FNC - 4,438,000 MSNBC - 2,571,000
25-54 demo: CNN - 2,811,000 FNC - 1,379,000 MSNBC - 924,000
One other impressive note. YouTube's top rated video yesterday was the twenty minute clip from CSPAN of the swearing in and inaugural speech. More than 2 million views yesterday beating the nearest competitor which had 350,000+ views.
