Below are four maps showing which team in each of this weekend's games has more Facebook fans in every county in America.

They're not hugely surprisingā€”each matchup features a team with historic success and the accompanying national popularity (Saints, Patriots, 49ers, Broncos) facing a team whose appeal is more regional (Seahawks, Colts, Panthers, Chargers). It is interesting to see where the borderlines are drawn, and these mapsā€”unlike previous onesā€”contain color gradations based on the percentage of supporters.

Be sure to expand each image.
