You might think tourism would be the island nation of Tuvalu’s biggest source of revenue. Think again! It makes millions every year from its tv domain name! Money made from the domain revenues mean that Tuvalu was finally able to afford the $100,000 it cost to join the United Nations. The payment also increased the country’s gross domestic product by 50 per cent and allowed the government to put electricity on the outer islands and create scholarships for its citizens.
