Today is one of those days where the weirdest thoughts come up. I was wondering is there a difference between am radio and fm radio and if there is what is it? Why is fm more popular?
FM allows for more bandwidth (stereo), which results in better audio quality (AM is Mono).
FM also is more robust to noise and interference, which improves quality even further.

The only real difference is frequency. On a side note, AM signals don’t travel as far.
