FM radio (at near 100MHz carrier) is pretty much local (the visible horizon is almost the limit). It is up to local authorities to allow FM analog broadcasting in the 88-108MHz band and up to local businesses to find a viable business model, no space technology needed. A few kW transmitter is damn cheap and works flawlessly.
My country (Bulgaria), while not really 3rd world, delayed its transition to digital radio for a variety of reasons, to the point it became pointless - both established FM radio stations and startups emerged online, mobile Internet connection is acceptably cheap and everyone has it on their phone. The transition to digital radio is expensive and no one sees any point for paying it up.
That's why we still listen to analog FM radio - including 2 government-controlled and quite a few private stations.
If one wants to establish a new station, they can get an FM frequency pretty cheap. And no one bothers anymore.
In short, FM radio is alive and kicking without any rocket science involved.
What about the analog TV? Well, we somehow succeeded in the transition from analog to digital TV. The TV band is already re-occupied by the digital broadcast. You are not allowed to broadcast analog TV anymore - no matter if you do that from a satellite.
And even if we talk about a country where digital TV is not on the table, your potential auditory will need to find analog-TV receivers.
And the usual kind of sat-tv is pretty much popular exactly in the developing countries. So no business model either.
MW and SW: they don't really play well with space.
First, one needs pretty much large antennas for them (not suitable for a satellite). How about 50m for a simple dipole?
And second, the same ionosphere that makes possible MW/SW reception over the horizon will make a Sat MW/SW quite a challenge.
A quick walk over the MW/SW band reveals a great deal of stations from all over the world alive and transmitting. These are alive as well and the space offers no possible improvement.
The peculiarities of the MW/SW bands makes them safe against any attempt of digitalization.
