The way to prevent that problem is to have several networks

available as I do.

I watch ABC, NBC, CBS, PBS. For cables, FOX, CNN, MSNBC, CBS and Bloomberg. Depending on the news and topic, I tend to watch more on one channel than others.

This way will help filter out "incorrectness". Among them FOX rates #1 in my view so far.

About CCTV, it is hardly called news orgranization. It is propaganda agency.
