Niue, a pacific island nation just east of Tonga, holds a little over 2000 people. According to the CIA world factbook, an important source of revenue for Niue is "the sale of postage stamps to foreign collectors."

Niue has only one ISP, but gets its own ccTLD, ".nu".
Glenn Fleishman has made a really neat-looking book searching site that, while hosted in what seems to be Seattle, has a .nu TLD in "an attempt to show how smarter systems combined with cleaner URLs can create shortcuts around roadblocks." (Much like this site, except for the shortcut-around-roadblocks part.)
