Fox News has been the #1 rated cable news network for over two decades. They've had more viewers than CNN and MSNBC for most of their existence. Calling them anything other than "mainstream" is just supporting their propaganda. They've always branded themselves as the scrappy outsider because it plays well with their audience, not because it reflects reality.

Yeah, but cable news only displaced local and broadcast TV news as the main news source after 9/11, and already by 2010 had itself been displaced by online media. There was only a very brief moment in history where "the #1 rated cable news network" was really an indicator of being a mainstream news source.
