CBS’ Sunday night telecast of Super Bowl XLVII scored the highest-ever overnight rating in the game’s long history with an average of 48.1, according to preliminary Nielsen data, despite a blackout at the New Orleans Superdome that delayed the action for almost 34 minutes.

CBS Sports said the game, a thriller in which the Baltimore Ravens held on to defeat the San Francisco 49ers 34-31, had a peak rating of 52.9 and a 75 share of the audience between 10:30 and 10:45 Eastern time.

In achieving the new record, the Super Bowl XLVII broadcast topped Super Bowl XLV’s 47.9 rating and  71 overnight share two years ago on Fox, a 31-25 win for the Green Bay Packers over the Pittsburgh Steelers.

In third place: Super Bowl XXI (CBS), the New York Giants 39-20 victory over John Elway and the Denver Broncos, which generated a 47.9 rating and 68 share.

The 56 markets where Nielsen uses people meters to monitor what viewers are watching cover all of the largest U.S. markets and many medium-sized areas.

Full results from the ratings service’s 210 markets will be available later on Monday.
