Despite, or perhaps helped by, a 34-minute delay because of a power outage, the Baltimore Ravens’ victory over the San Francisco 49ers in Super Bowl XLVII set a ratings record, according to CBS’s preliminary numbers.

The game, which lasted over four hours, was watched in an average of 48.1 percent of households in the top 56 U.S. television markets, CBS said in a news release that cited early Nielsen data. The Super Bowl between the New York Giants and New England Patriots last year was seen in 47.8 percent of households in the big markets.

The previous best of 47.9 was set by the Giants-Denver Broncos 1987 title game and matched by the 2011 Super Bowl between the Green Bay Packers and Pittsburgh Steelers.

The rating, according to CBS, peaked at 52.9 between 10:30 p.m. and 10:45 p.m. as the Ravens were holding off the 49ers for the 34-31 victory.

The game also was the biggest social TV event ever, with, according to BluefinLabs30.6 million social comments, an increase of 12.5 million from 2012. Here again, Beyonce and the power outage have to have helped considerably.
