Ratings Roundup

RATINGS ROUNDUP: Madonna’s halftime show earned a 48.1/72 share, which was more than the game itself, up 1% over last year’s Black Eyed Peas performance. NBC’s heavily hyped The Voice, benefiting from an earlier start time—10:15 to 10:39 p.m. last year for Fox’s Glee--scored a 19.4/33 share, up 27% for the same Super Bowl follow-up from 2011, though below the last time a reality series debuted after the big game, CBS’ Undercover Boss (22.5/36 share). The Voice was up, of course, a whopping 159% from its season premiere last year, when it was a sleeper hit on NBC's summer schedule. (2/6p)
