Well, there's your answer. Tickets are too expensive in today's economy. The hour and forty-five minute medal sessions tickets range from about $80 to $700.
not really, they had a long time to sell those lower more expensive seats and to figure out what to do if they weren’t selling.
again, i don’t think the average UK citizen is interested in the sporting events even the most popular ones (swimming/gymnastics). Most of the stadium left after the opening ceremony show when the parade of nation’s started. It was pathetic and disrespectful.
