They say that an announcement for LWN's replacement is coming soon, so fingers crossed that Buzzr is it. I believe they are owned by Media General, but I don't know if that would make any difference as to whether or not they could get it. I'm not very knowledgeable in the workings of TV.
Dunno if it's nationally, but in my market, Live Well was replaced by the "Justice Network", which is more or less TruTV for the cord cutters. They show a lot of TruTV reality (and I use that term
very loosely) shows like
Bait Car and quite a few forensic investigation shows.
It doesn't look like the station group matters.
According to Wiki, only one Media General stations plans to replace LWN, WKRN in Nashville. WBAY in Green Bay planned on replacing it with Decades.
Right now, neither plan has gone through, if Wiki's to be trusted.
