Obama's infomercial: A good call?

MSNBC's First Thoughts took a look at whether the campaigns money was well spent on Obama's 30 minute advertisement. They reported that almost 34 million people watched the ad. To put that in perspective, the NY Times reported Obama's 34 million viewers is more than the number of Americans that watched the World Series game that followed it, and also the finale of last season's American Idol. To break it down by networks that people tuned into for watching the ad: NBC had about 10 million, CBS had 8.6 million viewers, and FOX had 1 million viewers. From the numbers, it looks as though the Obama camp made a good decision on the ad buy.
