This Is Us fell to a series low among adults 18-49 Tuesday, although the NBC series was still the night's No. 1 show in the demo.

It was bit of a down night generally for ABC, CBS and NBC, all of whom slipped a little week to week. This Is Us posted a 1.8 rating in the 18-49 demo, its first time going under a 2.0. The Voice (1.4) tied its season low — set Monday — for NBC, and New Amsterdam held at 1.1.

The Conners (1.4), The Kids Are Alright (0.9) and Splitting Up Together (0.6) all recorded season lows on ABC, each losing a tenth of a point week to week. Black-ish fell two tenths to 0.8, also a season low, while The Rookie held at 0.7.

At CBS, NCIS lost two tenths to finish at 1.2, while FBI (1.0) and NCIS: New Orleans (0.8) each lost a tenth.

The Flash (0.6) and Black Lightning (0.3) held steady on The CW. Fox aired reruns of The Gifted and Lethal Weapon.

NBC averaged a 1.4 rating among adults 18-49 for the night, comfortably leading the 1.0 for second-place CBS. ABC came in third at 0.9, and The CW's 0.4 edged Fox's 0.3.
