so Supernatural was #1 in repeats last week and even beat some new episodes in ratings
Shark Tank still ends up as the top show of the night in the 18-49 demo, and in total viewers. Not sure if that will continue, but it’s doing fine.
Hmm, yep. ANTM’s sinking now that it’s getting into the season, proper. Still not doing any worse in the demo than Nikita in the same slot last spring, though.

I’m not surprised. There have been weeks this summer when Supernatural won the whole week, even over original programming.
