Desperate Housewives Into Space

Well, it can be the only explanation really. The following appeared on the BBC website today:

Hit US comedy series Desperate Housewives is named the best-selling TV drama, being seen in 203 countries - wrestling the record from Baywatch.

Which is in stark comparison to the Wikipedia entry for the number of countries in the world:

193 states with general international recognition:
192 member states of the United Nations (UN).
1 state with general international recognition but not UN membership, governed by the Holy See (a UN permanent observer): Vatican City.

Admittedly Wikipedia acknowledges 244 'entities' but some of them are of the likes of 'Christmas Island' and the 'Cook Islands'.

So who is right and who is wrong? If you care and know, please let me know!
