Some interesting history in this article but I'll highlight this portion:
The streak did come close to ending during the 2015 season. NU development officer Jack Pierce told The Associated Press last month he had to call up friends of the program days before three games and ask them to buy up tickets returned by the opponent.
That could happen more frequently unless they find a solution to an attendance issue thats become a nationwide problem.
CBS reported that average attendance nationally has declined every year since 2008. 2015 only saw a decrease less than 1 percent, but in 2014, it was 4 percent. And 2015s average attendance figure was the lowest recorded since 2000.
The Big Ten has seen a decline as well. The 2015 average of 65,998 was down from 66,939 in 2014 and 70,431 in 2013.
Nebraska has mostly avoided a significant decline in attendance. The Huskers have never finished outside the top 20 nationally dating back to 2003, and stadium expansions in 2006 and 2013 boosted numbers the following year.
But 2015 attendance was down. The Huskers average last season (89,998) was lower than the two previous years 91,249 in 2014 and 90,933 in 2013. The cost of tickets combined with the quality and availability of television broadcasts has encouraged fans to stay home.
