TV ratings for the NFL’s wild-card round increased 21% over last year despite most of the games not being in doubt going into the fourth quarter. The six games averaged 30.5 million viewers, making it the second-highest average for the postseason’s opening weekend over the past six seasons. CBS and Nickelodeon’s broadcast of San Francisco’s 23-17 victory over the Dallas Cowboys led the weekend, averaging 41.5 million viewers. The audience peaked at 50.2 million for the conclusion. It is the most-viewed game this season, surpassing the 40.8 million for the Thanksgiving Day game between the Cowboys and Las Vegas Raiders.
