To the OP: Fox figure out something that the others haven't been able to copy: How to make news entertaining.
Nah, I'm not saying they make sh*t up (though I suppose they could and probably have, like many of the others), I'm saying that they deliver the news in an entertaining way, by people who don't have sticks shoved up their backsides.
Even Brit Hume has a sense of humor. Go figure! For some reason, people get tired of watching what might as well be a CGI animiation of a reporter, and like seeing real people for a change. Even Alan Colmes was entertaining (is he still on there?).
