   FM radio had an effective stereo technology (almost?) from its   
   beginnings.  AM's version of stereo didn't arrive until the end of the   
   eighties, and seems to have been a failure.  When I was looking for a   
   car stereo in 2003, only the very expensive units seemed to have them,   
   while a friend's super-cheap car stereo in 1990 (Craig brand) had AM   
   stereo.   
      
   Without stereo, music is a hard sell.
