Olympic Tournament 2008 in Beijing is the only one exception.
*Arenas were filled but many tickets were for free and almost no fans from other countries.
All these tournaments had a common thing - many empty seats during matches of non-host nations.
Bad ticket sales policy?
FIVB/CEV/national federation did not promote the sport in a right way?
Maybe volleyball is just boring to watch and need new rules?
