I think FN's problems with programming when they decided to add Cooking Channel. So now, Cooking Channel has a lot of cooking shows and FN is supposed to be about Food, not cooking. However, not all carriers offer Cooking Channel with Food Network. Also, Cooking Channel seems to have a lot of reruns of older FN shows, shows from other countries and a few US based shows (i.e. Kelsey's essentials, etc)
FN is always a 'go to' station for me when I can't find anything else to watch on tv. For whatever reasons, I 'forget' that cooking channel is an option, too. I guess none of the new shows are consistently appealing. On CC, I usually end up watching reruns of Good Eats.
My favorites are Giada and Ina and their new episodes are usually on Saturday AM's. I don't care for Pioneer Women or Trisha's kitchen.... so, none of their newer hosts have caught on for me.
