Classical music is perceived by most people as snooty and elitist, something that cannot be understood without being initiated into it, like a private club. How did this come about?
In the context of Jazz it's laughable to suggest classical musicians have some superiority complex. [cf David Horne for example, you'll find the forum on google, and / or search usenet where's there's a plethora of people who, well go and see...]
At least the classical musicians superiority, as far as musicianship goes is logical....some of those Jazz guys often play Yamahas and digital pianos!

All music is as "dead" [or not] as classical.
The idea that any other genre is, via record executives or TV, about the music is a fallacy.
Besides, you can't make music "accessible" any more than you can make any other subject, e.g astro-physics, maths or computing accessible.
You can fool a few people into believing wiggling a mouse makes them computer literate though, but do you think Bill Gates made computing accessible? No. cf Knuth.
I don't see music being any different - anything I know about music, performance, theory and so on, isn't because I have a shelf of CDs or an internet connection or 40 channels of music on my TV.
The TV people trying to make it accessible here are people like Classical FM TV. Their team of highly paid chimps decided that to make it popular they wouldn't have classical music on it.
Instead they have the Browns [playing lord of the dance on 5 pianos, that's like a 3rd of a note each] and Maksim [playing with his genitals I think] and some school choir singing coldplay songs. Then a pile of dire italian arias.
Coldplay - that's a load of minor chord arpeggios played on the piano and a guy singing nasally over them about how miserable everything is. They are huge, think about it. If that's big, classical can't die. Indeed it sounds like a heavy sinus cold would just increase album sales.
They have the cheek to put in 5 minute adverts with a narrative something like "people said classical music was dead....they said we wouldn't get any viewers....over 3 million people watched our channel.." and such cobblers as that.
The imaginative scheduling for a genre as rich and diverse as Classical is basically 3 programmes "Morning" "Afternoon" and "Evening"..perhaps there's 4, one called "Night" too, so you can always tune into the stuff you like, err not.
Yet we have threads in here exchanging little clips of performances. People doing their own thing, concert pianists and so on - and that's just one instrument.
A complete halfwit could make a better classical music channel than they do, so you wonder who they have doing it.
In that small sense perhaps I agree with you. Classical music has a lot of halfwits that can't play and on the face of it have nothing at all to do with classical music, except perhaps some uni course. Complete buffoons [we've at least one here who I shan't name] if that's the kind of classical music person you're talking about that is ruining it / killing it or whatever, I'd probably agree, I bet there's a bunch in every TV station.
e.g Whoever decides every year to ignore every classical music event around the world, every video release, archive footage, new musicians, old musicians and so on and instead show the £$"£ing proms for example. Especially the last night.
e.g Who decides to dress up kids like that? I see people playing and they are wearing whatever clothes they usually wear [jeans or whatever] Then you see a comp or recital and they are dressed like something out of Oxfam shop, something that was removed from a dead body in the 1930s. Is that the musicians or some other hanger on as above that decides that's what pianists should wear?
