It wasn't just CNN's presidential debate that had trouble drawing viewers last night.

The Big Bang Theory hit a season low on Thursday, with a 3.5 rating among adults 18-49, down three-tenths of a point from its last original episode. But the comedy still managed to lead the night, as per usual. The rest of CBS’ lineup — including Mom (1.8 adults), 2 Broke Girls (1.7 adults) and Elementary (1.1 adults) — was even with last week, with the exception of Life in Pieces (2.1 adults), which was up three-tenths.

The CW, meanwhile, saw season lows for both Legends of Tomorrow (0.7 adults) and The 100 (0.4 adults). The same was true for ABC’s Scandal, which dipped down to a 1.6 rating. Shonda Rhimes’ other two dramas, Grey’s Anatomy (2.1 adults) and How to Get Away With Murder (1.4 adults), remained even with last week.

On NBC, Shades of Blue (1.0 adults) and You, Me and the Apocalypse (0.6 adults) were both steady on either side of a Law & Order: SVU repeat.

American Idol was off three-tenths of a point in the key demo, averaging a 1.8 among adults 18-49 and 7.6 million viewers on Fox. The two-hour reality staple wasn’t enough to pull the network into first place, as CBS inched past it to win the night with a 1.9 rating and an average of 8.23 million viewers.
