Update: The visualization below has been updated to include the 2018 regular season. The AFC enjoyed a 34-30 edge in NFL interconference play this season.

There have been 49 regular seasons since the NFL merger in 1960. There have also been four Super Bowls before the merger, bringing the total years of interconference play to 53. The user can hover over any of the seasons or the row for Super Bowls to see which conference had a better record against the other.
