Fear of Fox: It’s true that broadcast networks always had concentrated star-making power. They could make you. But could they break you? The key to Fox’s “make or break” power on the right would seem to be the disappearance of non-TV ways to make a good living as a pundit.  It’s harder and harder to feed your family as a plain old mid-list book author, for example. Book sales and lecture fees increasingly hinge on TV exposure. (The New Yorker may also have star-making power — it’s the non-TV exception that proves the rule! You don’t see many trenchant critiques of David Remnick either.) [Response to @RD_Mullin]
