The University of Minnesota made news in 2012 when the school announced it would sell beer and wine at its new stadium. The experiment has gone so well (reported profits of $200,000 from 2012-13), the Gophers expanded stadium alcohol sales in 2014.
Since there are no reports of somebody dying from stadium-sold alcohol poisoning, that's not a bad bit of business for a school that averages ~45,000 people at its football games.
So, it's of no surprise that Ohio State — a school that knows a thing or two about business — hasn't yet killed the idea of selling booze in the Horseshoe.
