AM radio is only available in the mornings. ;-)
AM = amplitude modulation
FM = frequency modulation
But that doesn't mean much to non-technical people, and there's a pile of
pros and cons for each.
In the real world the difference in AM and FM basically comes down the
frequency bands used by the stations. It has no bearing on what they
actually play, although many newer stations aimed the "younger generation"
that play mainly music mostly use the FM frequencies while the more
established stations for the "older listerners" are usually AM (or both AM
and FM in some cases).
