Spring is not good for TV ratings.
Over on ABC, Grey's Anatomy (6.5 million/1.4 rating) fell three-tenths to its lowest ratings yet in the 18-49 demo.
Station 19 (5.2 million/0.9 rating) also took a hit with a weaker lead-in. Quantico (2.8 million/0.5 rating) returned after a year off the air, and it failed to get a boost despite some significant retooling.
CBS: The Big Bang Theory (11.5 million/1.9 rating) and Young Sheldon (11 million/1.7 rating) hit new series lows.
Mom (8.5 million/1.3 rating) lost a tenth while Life in Pieces (6.3 million/1.0 rating) and S.W.A.T. (5.3 million/0.8 rating) held steady.
The CW: Supernatural (1.5 million/0.4 rating) slipped, while Arrow (0.9 million/0.3 rating) held steady.
NBC: Superstore (2.9 million/0.7 rating), AP Bio (1.8 million/0.5 rating) and Chicago Fire (5.4 million/0.9 rating) were down, but Champions (1.5 million/0.4 rating) was stable.
