Why do Fox News reporters never have the Fox logo on their microphones when reporting on location?

Question

Do they not want people at the scene to know they're from Fox to avoid ridicule and interruption on camera?

Answer 1

Because "Fox News" isn't really news, just lots of opinionated commentary.

Answer 2

because it's on their jackets or name tag.

Answer 3

I never noticed that before.  

Answer 4

Because there is no reason to advertise..either you watch FoxNews or you don't. Most of the reporters are known by their face anyway.
