An average of 108.41 million U.S. viewers watched the Baltimore Ravens defeat the San Francisco 49ers in Super bowl XLVII on Sunday, making it the country's third-most watched TV program, CBS said Monday afternoon.
That's down almost three million viewers from last year, when Super Bowl XLVI averaged 111.3 million viewers. Super Bowl XLV in 2012 averaged 111 million viewers.
CBS had said earlier on Monday that initial Nielsen measures of metered markets, a roundup of the most populous regions of the U.S., showed that the Super Bowl had earned an average overnight household rating of 48.1 and a share of 71 in metered markets -- enough to make it the highest-rated Super Bowl yet in metered markets. But this afternoon it said the household rating was 46.3 and the share was 71, making it "the second-highest-rated super Bowl in 27 years."
A ratings point represents one percent of the number of TV households. Share is the percentage of TV sets actually in use that are turned to a given program.
Topping 108 million viewers will still make the Super Bowl, as usual, the biggest TV event of the year. Average viewership on Sunday peaked at 113.92 million between 10:30 p.m. and 10:47 p.m., CBS said.
