The new brand and focus seems rather more downscale and less curated than their current schedule... although I suppose one man's "Petticoat Junction" is another man's "Full House."
Overall, it's not going to have a huge impact on their schedule, since most of Decades was comedy anyway... but sadly, this does mean the end of nightly "Dick Cavett Show" reruns. (Just last night I caught part of a 1971 pre-bout showdown between Ali and Frazier, which was truly a glimpse at a bygone era.)
I believe the only dramas on their regular schedule were "Dark Shadows" and "The Millionaire," both buried in the 5 a.m. and 6 a.m. hours. But they did often feature dramas on their weekend binges - "77 Sunset Strip" this coming weekend (including the complete "noir" final season) and "The Mod Squad" the weekend after that, just before the rebranding begins. I wonder how often we'll see dramas like that on subchannels in the future.
