The Big Bang Theory S09E17 Still - H 2016

The end of the season is in sight, as evidenced by the growing same-day ratings fatigue of many broadcast series. (Cinco de Mayo may also be to blame, with adults 18-49 TV usage down 10 percent from the same night last week.)

The Big Bang Theory, perennial Thursday victor, took a steep spill to its lowest adults 18-49 since its first season. That score, a 2.9 rating among adults 18-49, still wiped the floor with everything else on broadcast — though it was off four-tenths of a point from the previous week.

CBS' subsequent series — comedies The Odd Couple, Mom and Two Broke Girls (all averaging a 1.6 rating in the key demo) and drama Rush Hour (0.9 adults) — held steady with last week.

Steady was also the case with ABC's block of Grey's Anatomy (2.0 adults), Scandal (1.5 adults) and The Catch (0.9 adults) and Fox's duo of Bones (0.9 adults) and American Grit (0.6 adults).

Over on NBC, Strong (0.6 adults), The Blacklist (1.2 adults) and Game of Silence (0.7 adults) also held. The CW aired steady episodes of Legends of Tomorrow (0.6 adults) and The 100 (0.4 adults).
