The new owners also own the America One network, which seems to consist mostly of LPTV's. I'm thinking we may see 55 clear a lot of that programming.
KTBU had a hopeful start in 1998 with reruns and syndicated fare 16 hours/day, while infomercials took up the remaining eight hours. Those numbers are reversed now, so any change will probably be a positive one, though I doubt we'll see any major impact on ratings.
KTBU could still be headed for a duopoly with either KPRC/KHOU/KTRK if and when the new owners decide to bail.
