Boring fact for anyone who missed the joke earlier.
Third World was used during the Cold War to define nations that didn't fall into an ally of NATO nations or the countries that made up the Warsaw Pact. In fact, most Third World nations were often former colonies of the other powers, and while in recent years has become a byword for developing nations, the truth is that the concept has become long dated, as it described a global political situation that no longer exists.
Surprisingly, European Third World nations include Austria, Switzerland, Finland, Sweden and Ireland, all of which have become economically successful and prosperous in the 30+ years since the fall of the Soviet Union.
