via press release:
SUPER BOWL XLVIII AUDIENCE NOW 112.2 MILLION; RATING 46.7
Earlier today Nielsen issued FINAL Live + Same Day national ratings for Super Bowl XLVIII and both the household rating and average audience figures have risen compared to the time zone adjusted fast nationals released yesterday.
The average audience for the game has increased to 112.2 million viewers, up from 111.5 million reported yesterday, which was already record-breaking. The household rating for Super Bowl XLVIII now stands at 46.7, up from a 46.4 based on fast nationals issued Monday. Super Bowl XLVIII now ranks alone as seventh highest rated Super Bowl ever; at 46.4 it had been tied for seventh best. The 69 share reported yesterday is unchanged.
It's not uncommon for the final national figures to deviate from the fast national by roughly 1%. In most cases, the difference is insignificant, but with an audience the size of the Super Bowl, the adjustment can result ratings and audience being altered.
