Perhaps we gave it a name now as in the past people wanted music as close to Live based on the recording quality then , since the reference was live un-amplified music for them and so it was for the designers. Being a relatively big market so many smart engineers got out of college to go into the audio business to develop cutting edge stuff in audio to do just that.
Just like in the past we had doctors..then we had specialisation into surgeons, then spine surgeons and now surgeons specializing only in C1-C4

.
I guess similarly before there was live music which was the test, then we started analysing and specialising it into different factors and now we have speakers with disappear the best, best soundstage, best bass, midrange kings, flat curve etc etc...
Maybe so have peoples tastes in music as well as we may want different things despite everyone claiming they want the best music the paths they choose can be different.
