Probably so. In many parts of the world, the population is too scattered
to be effectively served by AM and FM, and too poor to afford the
internet or satellite. The reason the BBC keeps broadcasting English to
the Caribbean is because it's less expensive than establishing FM relays
in all the former British colonies scattered across the sea. It also has
the side effect of getting a couple hundred listeners in the southern
US. In the future, there will be less English on SW because most
countries that speak English are advanced enough to not need SW.
