The history of how performing arts came into existance is simple that everyone wanted ways to enjoy viz. Dance, music, drama etc to rejoice. It depended on their liking and sensibility for a particular form of performing arts. Since music karnatic/hindustani is classical and required certain chaste approach, it couldnt attract masses to it but was limited to certain sections of society, as per the then rulers' liking. We read in history that during certain rulers' time, there was development in Art and music and some tried to destabilise etc. So it doesnt seem like some section tried to restrict it but more or less it is liking. Its a fact that most of us prefers cinema/TVshow to a music concert, as later required some sensibility that might be genetic!!!
