Well aren't you special.
This might come as a surprise, but videos that include the original audio are also available. You should try looking into this "yootoob" thing.
ETA: So what's the point of even mentioning how you'd rather DIE than watch a video with the audio overdubbed? Besides, aren't you making a point about how you don't watch Fox? Watching vids counts as watching Fox. That's how people know what they say on Fox. They watch it.
Seriously, what exactly do you want to know? This question makes no sense.
ETA again: Oh, ok, that makes more sense. Yeah, I've never understood how it's possible that cable news is constantly struggling to fill up 24 hours each day, but they refuse to do so by going in-depth on anything. Sad to say, but the reason they don't is that their ratings would drop if they did.
News departments for TV and radio stations used to be considered loss-leaders, meaning that they wouldn't make enough money off of them to cover expenses. They did it anyway as a service to the community in exchange for being given a part of the radio spectrum for their broadcasts. Today, news is expected to make money, and that means keeping things light and entertaining and chasing down "hot" stories while ignoring important but boring stuff like figures and policy.
As far as I'm concerned TV news is on the same level as reality TV when it comes to being informative. It's only there to draw eyes to the Brawndo ads they run.
Sorry if I seemed a little too hostile. Fox Noize makes my blood boil. I don't have any better answer than, "well at least we have the internet." But TV news has become TV propaganda, and that's a problem for us whether we watch it or not.
