Wired.co.uk published an article that included a map of the world ( courtesy of Nominet) which focused on domain extensions.
The story spent a lot of time on .TK the cctld of Tokelau being the largest spot on the map. With more than 31million regs it leads all extensions. Of course they are free.
From the article:
FreeDom makes money through adverts placed on lapsed .tk registrations, with a cut of this passed onto the people of Tokelau. In 2012 this cut accounted for one-sixth of its tiny $1.2m annual GDP.
More recently .ml (Mali), .cf (Central African Republic), .ga (Gabon) and .gq (Equatorial Guinea) have all opened themselves up to free registrations.
“Our visualisation of global internet use paints an interesting picture of the domain world,” said Nominet CEO Russell Haworth, adding that the high internet adoption rates in Europe gave it a much larger geographical size.
