The 2014 version of the St. Petersburg Bowl at the Tropicana Field was called the Bitcoin St. Petersburg Bowl. You could not use Bitcoin to pay for tickets, concessions, souvenirs, parking or anything else at the game nor were North Carolina State and UCF paid their $500,000 fees in the equivalent Bitcoin amount. Fully understanding that the sponsorship was purchased in the name of getting publicity, I still have to say that the game was on TV in a bar some friends and I were drinking at and we made a seemingly endless number of dumb jokes and comments about people at the game attempting to buy stuff with Bitcoin only to be told to get lost by confused stadium workers.
During the Super Bowl in January, a number of area strip clubs got equipped to accept Bitcoin. The strippers had QR codes on their arms that could be scanned and there were Bitcoin ATMs on site. That's when I knew it was starting to take off. New tech always starts with naked chicks.
It definitely says something about the rise of Bitcoin and possibly also about the demographic of Bitcoin adoptees.
