Thanks for the lessons, but I think most of the people on this site are already aware of the history and genesis of jazz music. The question is why is it so unpopular? No pun intended 
The answer is complicated, much more than a "dumbing down," a term I dislike because it always makes the person using it, regardless of who they are, sound like a supercilious elitist. Who am I, and I myself have been guilty in the past, to look down with condescension on people who don't share my love for jazz? I personally love classical music, but I dislike opera. I appreciate the talent and artistry involved, but I just can't take the voices. So, to opera lovers, I guess I've been dumbed down. The reality is that jazz and opera are both esoteric art forms that have relativly small fan bases and it isn't an intellectual faux pas to prefer one over the other. Does the same line of logic apply to rock, rap and country?
