update: now confirmed. And this explanation via an AP story is…something (emphasis mine):
Nielsen explained the discrepancy of more than 3 million viewers by saying a more complete check of their records revealed additional viewership on some digital tier networks. The company hadn’t been aware that they were showing the game.
we hear from a reliable source or two that after additional counting Sunday night’s Super Bowl featuring an awesome contest where the Pittsburgh Steelers ultimately defeated the Arizona Cardinals is now the most-watched Super Bowl ever, eclipsing even last year’s game which averaged 97.448 million, with a 98.7 million average.
Previously it had been reported that Sunday night’s game averaged 95.4 million, which would’ve made it the second most-watched Super Bowl of all time.
We still haven’t seen the data, but if true, we will see it in any number of ways including an “Super Bowl XLIII Second Most Watched Super Bowl Ever” press release from NBC.
Here is the updated press release via NBC (nice headline!):
