I've never seen anything on their TV's besides HGTV or some Blu-ray or other, usually a kids' movie.

Not one of the doctors I go to has FoX News on, but all of my doctors but one is a member of the University of South Florida Medical Group..

Thank goodness mine plays HGTV. My old doctor had a mix of FOX and CNN, so it depended on what day I showed up.

Where I am in WV, ALL waiting rooms with TVs have Fox on, although some places with more than one (McDonalds) may also have CNN or a sports channel on. I suspect it's the local area that drives the channel choice. Do waiting room TVs in Washington DC or Boston have Fox on? I doubt it.
