Why does AM radio still exist?

AM radio never seems to be a strong, crisp or loud as FM. Why does it still exist?

Because people listen to it.  Typically, AM radio is not used to broadcast high quality audio but instead used for voice... talk, news, etc.  Government rules regarding bandwidth use and broadcasting requirements make it fiscally advantageous for certain types of broadcast outlets to use AM instead of FM or something else.

Also, there is a nearly universal installed base of receivers in use.  Replacing them would be very costly for everyone.

Bottom line:  AM fills a need, and until that stops happening, it is not likely to go away.
