Visa, The Only Card Accepted There

I love Visa's "Go World" Olympic Campaign. It celebrates inspiring moments in Olympic's history, not just victories, as seen by this Derek Redmond Ad (who popped his hamstring in the race):



Also be sure to check out Kip Keino's victory on the Visa site, which was the marked as the beginning of Kenyans being awesome runners.

However, it sucks to me that they have monopolized the credit card industry (though I know it's common practice to do so; does anyone accept Discover anymore?) for the games. Nothing would suck more than waiting in line with your American Express and being denied awesome Olympic swag.
