My thinking is that by the time the 2010 challenge finally arrived everyone was bored to tears by the whole fiasco.
Now while the previous event gained more world wide media attention it didn't get a lot of television coverage did it ?
Certainly neither free to air nor cable/satellite picked up the rights in Australia.
I don't know about the rest of world.
One of the problems to be faced is that the Little America's Cup is now indistinguishable from the Big AC in everything except the size of the boats and the multi hull regatta that was held recently (I forget the name) also takes away from the AC.
Me, I reckon what fuels the AC is nationalism. This last schemozzle took that away. While everyone should have been cheering on the Swiss underdog v the might of the Evil Empire, Bertarelli managed to alienate almost the entire planet. What a nonsense.
