NFL Attendance Numbers Dropping, Football Losing Popularity? Fan's Take (Yahoo! Contributor Network)

In recent days there's been some attention paid to the fact that NFL attendance numbers are the lowest they've been since the league expanded to 32 teams in 2002. That year, 16,883,310 attended a total of 256 games. In 2011, 16,562,706 fans attended the same number of games. Average attendance at each game was 64,698 which is the lowest average since 2002. Are we seeing real evidence that the NFL has peaked in popularity, or are there other reasons for why these numbers have dropped?
