Crazy Noise on Fox

Ok, last week I posted about the annoying, cell phone-esque noise during the Emmy's.  Apparently, it wasn't just an Emmy's thing.  One of my other readers noticed it during an episode of Glee.  It's now going strong during Sunday football.  I read on facebook that tons of other people notice it, and that it was also noticed during other shows (Fringe was the one referenced).  It apparently isn't every Fox show, because it was absent during The X Factor.

Ok - two questions:

1)  What is it?

2)  It's all over facebook/twitter.   Mind you, there has to be some Fox employee somewhere watching the shows as they air, I am assuming.   Or, at the very least, there must be some PR person keeping a watch on social networks...my point being- it's been a week of this nonsense - FOX has to be aware of it at this point.  Why can't they make it go away?  Is it some bizarro glitch they can't fix?  Is it, as someone suggested, an attempt at a subliminal message?  Are they trying to force me to vote republican?  Will it work?

Ok, that was was more than two questions.  Sorry, my readers.  Your thoughts?
