mainstream media

Mainstream media is the big, widely watched news stuff, like major TV, newspapers, and radio, that most people end up seeing or hearing about first. Online, people use it like a shortcut to mean, “the usual outlets,” sometimes even with a side-eye that says, “they are biased or out of touch.” Basically, it is the group chat version of TV news, except everyone pretends they are the only one reading the fine print.
