My guess is it would be eaiser to sell blocks of programming rather than just plain weather. The shopping channels have went off the air for years. I think QVC used to show a fireplace with a burning log with Christmas music.. Now its mostly local choirs and employee bios.
I won't have any problems with TWC going off on Christmas. I would like to see a national scroll of warnings/advisories continuous and airport delay maps once in awhile.. There will be a lot of people traveling and many staying in Motel rooms..
