The NBC-only broadcast of Steelers-Chiefs, the first-ever Sunday NFL Playoff game to kick off after 8 p.m. ET, averaged 37.1 million viewers – ranking as the most-watched primetime game ever in the NFL’s Divisional and Wild Card Playoff rounds. TV viewership for Steelers-Chiefs peaked at 39.1 million from 9-9:30 p.m. ET.

Sunday's viewership topped by 8% the prior primetime NFL Wild Card/Divisional Playoff record set three years ago by NBC’s Saints-Eagles NFC Wild Card telecast (34.4 million viewers on Jan. 4, 2014) and was 10% higher than NBC’s primetime Saturday Divisional Playoff game last year (33.7 million for Packers-Cardinals).

The start time was moved due to an ice storm in Kansas City.
