It will be more difficult to receive some English broadcasts outside of these areas, but far from impossible. Some stations, such as BBC, Voice of Russia etc. broadcast English to just about everywhere in the world. Other stations broadcast the native language of their country in such a way, often to places where the audience for that language must be very small, but their government sees it as a priority. So don't be suprised to hear languages such as German in places like North America or even Africa. As for programming of international broadcasts, well it contains a very varied selection.
News is often the most favourite.
The news service can also alter depending on where you listen. In the developed world, the news broadcast will be a mix of international news and news from the broadcasting country. The mixture between the two can vary dramatically. In poorer countries, where information is rather scarce, there are also news broadcasts about the listener's area, such as Asia or Africa. Other popular genres of programming include music.
