The Super Bowl this year drew in 123.4 million viewers this year, making it the most viewed programs since the moon landing. (The last time the 2 played in a Super Bowl in February 2020, the game had 102.1 million viewers.)
For further reference, last year’s Super Bowl - which also featured the same Chiefs team playing an even larger media/metro market team in Philadelphia - only saw 115.1 million viewers, a number only slightly up from the prior years’ 112.3 million viewers (LA Rams vs Bengals).
