Hence why I made the distinction of maturing technologies. There are still some countries that operate 2G GSM technology only.There is a big difference between Burkina Faso, which is not even a third world country, and a first world one like Chile. Or Albania and France. And so on.
Of course, streaming won't take off there anytime soon. But eventually? Yes.
Which is why I made it clear that each country is different. Adaptation will depend largely on the wireless solutions/infrastructure of each country. Of course, there will be other factors that will come into play (costs of WISP, streaming service accessibility, technology affordability, etc.), But at the end of the day, infrastructure will be main barrier.So don't use foreign situations as an analysis point for U.S. radio.
Terrestrial radio will survive longer in other parts of the the world (maybe even for several decades). But it is not mortal. It will die as well once connectivity becomes more affordable in third world countries and the commercial viability of terrestrial radio is severely weakened.
