Outside of Hong Kong, Singapore, the Vatican and other city states, the internet dot extension for everyone else is either .com or .country code (not to mention .edu or .org etc.).
This story is quite interesting though. ICANN, the people who regulate these sorts of things, gave authorization to allow .bzh and .paris for those in either Breton or Paris, respectively. While more extensions do lead to more confusion (and problems for marketers abound!), there is some sense to using more micro level geographic extensions. Expect a .nyc and .london soon!
