Ever wonder who the most loyal NFL fan bases are? A recent Nielsen Scarborough study might help reveal one factor in determining that. According to the study, the Green Bay Packers boast the country's most interested fans in terms of gametime viewership. 84 percent of adults in the Green Bay market have either attended, watched or listened to a Packers game in the last year. That's the greatest market share percentage in the league by a long shot, with New Orleans' viewership second at 78 percent. The Packers have been in the number one spot since 2011.

The Saints, Steelers and Broncos also dominate their markets - and have done so consistently - but the Seattle Seahawks' numbers are what truly grab attention.

Despite a magical Super Bowl run by the 2013 Seahawks, only 44 percent of that team's market either attended, watched or listened to Seahawks games last season. However, Forbes' Darren Heitner notes that the team increased its market attention by an incredible 27 percent, a jump that isn't made easily in the NFL.

That growth counts as the largest jump of any NFL team according to the Nielsen Scarborough analysis. The Seahawks’ success on the field is a large part of that surge; however, such growth is particularly noteworthy since NFL teams rarely rise up the rankings to such an extent, regardless of an increase in performance. NFL teams, by and large, tend to be pretty consistent in these rankings each survey.
