PBS turned to social media last week to promote its airing of "Downton Abbey" against the Super Bowl. The public broadcasting service asked on social media sites whether people wanted to watch drama or the game, and an estimated 6.8 million people watched "Downton Abbey" on Sunday. While that's down from the season average of 8.6 million, it was 200,000 more people than the British drama had going against the Super Bowl last year.
Fox said that 25.8 million people stuck around after the game to watch the comedy "New Girl" with Prince as guest. The Golden Globe-winning comedy "Brooklyn Nine-Nine," which followed "New Girl," had 14.8 million viewers.
