> ccTLDs reflect the ISO country codes of each country, and are intended for use by those countries, while gTLDs are arbitrary and reflect the fact that DNS was designed in the US. The ".gov" gTLD, for example, is for use by the US government, while the UK is stuck with ".gov.uk".

Fun fact, the UK's ISO country code is not actually "uk", but "gb". IIRC, ".uk" was grandfathered in (from JANET?) as an exception: ".gb" officially existed for a while in parallel, but no one ever used it and I think it's now defunct.
