Why don't kids nowadays know about Jazz and classi

I speak to alot of younger people nowadays that have no clue about jazz and classical music. When I was a kid I knew most of the Jazz artists and I was only 14 years old.
That was back in 1974. Today the kids don't even know bands like Allman brothers and the Eagles. Some educators that I know say the kids today are much smarter than my generation. I find that hard to believe. I would love you're imput on this subject.
