If you think about it, the whole tribute thing has to be post radio/recording. Prior to that, the only time you would hear things played would be live so, to all intents and purposes, for most people, the first time you heard anything, particularly art music, may have been the last.
I think the originals thing was always one fo the defining characteristics of pop music post Beatles and became a badge of honour accordingly. Some have bought into that ethos, others haven't. It has never been an exclusive prerequisite of success in pop or rock, just an aspect of the content which some gravitate towards. No more definitive than guitar bands vs. synth bands. You either like them or you don't. For me, composing and listening to original music has been the main attraction; I don't even like Jazz standards really and regularly don't buy recordings of 'standards' albums by players I otherwise like. Horses for courses. If I hear a cover, I rarely (but not never) think 'Wow' and usually dismiss it as pointless. Not a universal truth, just my perspective on the thing..
