With few exceptions the corporate mainstream media operate within very narrow parameters. In one corner you have MSNBC’s Rachel Maddow and in the other you have Fox’s Sean Hannity. And they do present contrasting views but the boundaries of discussion are limited. Certain topics are taboo, such as U.S. imperialism or really existing capitalism, not the wonders of the free market propaganda we're bombarded with. Deep institutional structures are never the focus of attention. Here and there people make mistakes and are called out. And tactics and policies are criticized but the overall framework of power remains intact and unchallenged. The corporate mainstream media fulfills its role as a cover for a system that is clearly failing for the many but benefits the few. But there are alternatives to the BS.
