Ratings: ‘Young Rock’ Enters the Ring to 5 Million-Plus Viewers
Kenan Thompson’s “Kenan” premiere draws more than 4 million

NBC’s “Young Rock” just got some pretty grown-up Nielsen numbers from its series premiere.
Dwayne “The Rock” Johnson’s sitcom topped 5 million total viewers on Tuesday. Immediately following, Kenan Thompson’s “Kenan” debuted to more than 4 million viewers. “This Is Us” at 9 didn’t disappoint either.
NBC finished first in the key ratings demo last night, but finished second in total viewers to a trio of CBS reruns.
