For further comparison, the current #1 is Super Bowl XLIX from 2015, which had 115.2 million pairs of eyes glued to the screen for the Patriots victory over the Seahawks.
After the final tallies were figured out, the NFL announced over 118 million people watched Lady Gaga’s performance when it aired on Fox.
More people watched Lady Gaga, though.
So if it was a standalone piece of TV programming, it would have been the most watched TV broadcast ever, but as it stands, it’s just part of the overall Super Bowl telecast, which reached an average of around 111.3 million viewers on February 5.
