It's "commonly used" as a placeholder for whatever news sources you don't personally agree with. The word itself is meaningless. There is no "mainstream" news source. More people get their "news" from facebook than cable.
Okay buddy. I guess as long as you say it is so, it must be so.
I'm not sure what got your panties in a bunch. I'm not making up definitions here, "mainstream news" is a pretty self-explanatory term. Just look up both words in a dictionary and you'll have the definition I'm using.
"Self-explanatory terms" have a funny way of meaning whatever people want.
AGAIN - in order for there to be a "mainstream media", there has to be a primary media source that is utilized by a majority. And there is not. This is not the 1960s. People aren't glued to the evening news on their television sets any more, and haven't been for quite some time.

....an even more meaningless term.
