In the news link you posted, it says CNN is losing marketshare because it is the MOST OBJECTIVE and LEAST PARTISAN cable news network of the dominant American news networks. Very interesting because my perception is that CNN portrays itself as the unbiased counterpart of mainstream American media but simply packages news presentation in a less obnoxious way than say FOX News which portrays news in blatantly right-wing conservative fashion.CNN is doomed, however it isn't because most Americans wake up from the reality and stop watching CNN news. Instead they favor Faux News now, therefore the average IQ in American public is getting dumber and dumber.
It seems that CNN was doing really badly in 2009.
