I assume it's the OTA channel in your market that carries Fox programming like American Idol, The Simpsons, etc.
You may not get it OTA if you have satellite or cable, but it's typically called "local" stations.
you mean like the alphabet networks?
I only watch them during Foot ball Season and once in awhile during baseball..
otherwise I don't tune in...too old for American Idol and the Simpson's is to simple for me...so I would rather grab my Kindle and a comfy seat in front of the fireplace...and gather my three fur babes around me...
A Soft Coated Wheaten terrier
A kennel kid
and mini Schnauzer..
all three spoiled..and loved unconditionally.
