The revolution which CNN televised was Tiananmen. Just about everything since has been pretty much a production, Desert Shield and Desert Storm spectacularly so (e.g. very little in depth coverage of carnage on the Highway of Death, and lots of guncamera footage of smart bombs over Baghdad).

So is CNN, and it was pretty amazing in its day, which I remember. (The first gulf war.)
It's just neither is the place for revolutions.
If there's something after the Internet, that may possibly be subversive.
