It's anecdotal but as a kid we had japanese anime on tv. There was a surprising amount of quality (considering the tech used for production). And some animes like saint seiya, have .. to my half educated ears.. world class OST [0]. Others like Space Adventure Cobra also featured very fancy jazz funk. It's somehow unbelievable that at the time, companies would allocate money for such features. Maybe it was the spirit of the era.. a kind of spiritual drive in the air (new technology, promises of the post war future, rising tv market) making people doing their best.

And I can't help thinking that this energy is gone. It's done, known, technology made everything available so there's no real drive needed to try setting up a show and broadcasting (an few iphones could do).
